Thinking about Buying a Used Porsche Boxster?

Thinking about Buying a Used Porsche BoxsterAre you thinking about buying a used Porsche Boxster? At Shaus Motorsports in Aurora, we like the Boxster, because in all its generations, it has enough talent for the serious drivers and enough style for the Sunday fun crowd. Here are a few notes if you’re thinking of adding one. Boxsters can be quite affordable which makes them appealing. Here are a few things to keep in mind when you consider buying one.

First Generation (1996-2004)

There is a lot to appreciate about the first generation of Boxsters. It was a runaway success for Porsche. It had the style that Porsches were known for while keeping its racing engine and excellent handling. Though some Porsche enthusiasts of the time may not have viewed it favorably, the first generation Boxster was a big success.

If you are thinking of buying a first generation Boxster, check for oil leaks because the rear main seal is known to fail. Though the seal is inexpensive, the labor to get to it can be a bit pricey. Keep in mind too that the early first-generation engines had intermediate shaft issues, specifically the dual-row bearing. If and when it fails, the engine will need a rebuild, which is not a cheap endeavor.

Other areas to check include the main oil seal, the clutch and bearing, the cylinder heads, ignition, and water pump. While that may sound like too much, there is a high probability that a previous owner has already addressed many of these issues, so don’t let the list deter you.

Second Generation (2005-2011)

If you’re thinking about buying a used Porsche Boxster, the second-generation model was considered evolutionary. These Boxsters had both increased horsepower and torque. They also included better technology, greater efficiency, and direct fuel injection.

Many of the first generation engine issues were solved so potential buyers need to check the usual suspects: accident repairs, uneven tire wear, and service history. The only issue that sticks out for the second generation is the suspension springs. A broken suspension spring should be pretty easy to notice—one corner of the car will be lower during the test drive or you will hear a noticeable noise.

Pre-purchase Inspection

Like many other cars, a comprehensive pre-purchase inspection is a worthwhile investment. Be sure that the inspection includes a laser wheel alignment check, which will potentially show you if the car has been in an accident and whether the repair was up to standard.

Be sure that the Boxster includes the windbreak between the headrests, the roll bar inserts, both sets of keys, and manuals. These items can be easily overlooked and are expensive to replace. Ensure the fabric roof works properly and is in good condition. Don’t skimp on doing your homework. There are a number of Boxsters on the used-car market and you want to make a wise choice.

Are you thinking about buying a used Porsche Boxster? We can perform a pre-purchase inspection or look over the one you already own, here at Shaus Motorsport in Aurora. We can help you figure out if the Boxster is in need of some work or if it is ready for you to enjoy out on the road.

BMW is Working on Autonomous Cars

BMW is Working on Autonomous CarsAt Shaus Motorsport in Aurora, we’ve been keeping up on the news that BMW is working on autonomous cars. As you may know, BMW is making big waves in the car world with their 2017 5 Series because it makes a significant advance towards driverless vehicles. Though there are enthusiastic supporters of these cars, some BMW drivers are not keen on giving up control behind the wheel. After all, these vehicles are exhilarating to drive which is why people buy them.

Now that BMW is working on autonomous cars, we’re getting more details and seeing a number of benefits that might sway the skeptics. Take a look.


The biggest advancement is the Car-to-X-app. Why? Because many proponents of autonomous driving believe that cars need to communicate with each other in order for driverless cars to work safely and accurately. The Car-to-X-app allows the 5 Series to share its information with other BMWs. It is the culmination of the work of the 5G Automotive Association which includes BMW and other car manufacturers as well some of the leading telecommunication companies.

Remote Control Parking

One of the fun features of the 2017 5 Series is that you can park your car much like you would park a remote control toy car from your childhood. This will help when a driver needs to fit into those spaces that just won’t let you open up the driver doors. Just step out of the car, guide it in, and when you need to leave, use the Remote Control Parking feature to guide the car back out again.

Semi-Autonomous Driving

The semi-autonomous system is supposed to help avoid accidents. This system warns the driver of a potential on-coming collision so that they have an opportunity to maneuver away. Additionally, the system will pre-condition your brake system, as well as steer and accelerate up to 130 mph. The system is also designed to help avoid speeding tickets by automatically adjusting the speed to a max of 9 mph above the determined speed limit.

Driver Assistance Plus Package

All the new capabilities are part of the 5 Series Driver Assistance Plus Package. Basically, BMW took the Active Driver Assistant and put it together with the Driver Assistance Plus II to create the Driver Assistance Plus Package. In addition to all the features we already listed, this package will perform lane changes, keep the vehicle in its own lane, and avoid obstacles. It also assists with navigation. All these features make the 2017 BMW 5 Series a very exciting step forward in driverless cars.

Ultimately, driverless cars are something to be excited about and it is wrapped up in a classy car that offers a great deal more in terms of technology. Now that BMW is working on autonomous cars, we plan to keep an even closer eye on their next step too—we certainly want to see what will be next.

If You Drive a German Car, You Need a Higher Octane

If You Drive a German Car, You Need a Higher OctaneAt Shaus Motorsport in Aurora, we caution our customers that if you drive a German car, you need a higher octane. This is not just a guideline or suggestion, but it really is the way your high-end engine is designed to run. If you ignore this rule, you run the risk of expensive damage to your engine and your bank account.

Premium Octane is a Necessity

Why does your German car need a 91 or higher octane? Simply put, German vehicles are built for high performance and use a higher horse power than your average engine. German engines are considered to be high compression engines. These engines, when running on lower octane fuels, produce uncontrolled combustion called a ping or a knock. Over time, knocking can cause serious damage to your engine. The higher the octane of your fuel, the better the fuel’s ability to resist knocking.

Saving Money in the Short Term can Cost

High-octane fuel can be pricey, particularly in summer when fuel prices rise. It can be quite tempting to reach for lower octane fuel to save money. Initially, you will not notice much difference. It may even seem like your engine is adjusting to the lower octane fuel. In reality, your vehicle engine is suffering a slow and steady beating.

Understanding Octane

It is important to understand exactly what the higher octane does. Higher octane does not have more energy capacity than regular fuel. It has a much higher resistance to knock. Knowing this advantage, German car manufacturers design engines with maximized performance, using the higher octane as protection from the premature fuel combustion (also known as pinging or knocking) that comes with maximized performance. The engines can pull out more power from the gasoline and still remain protected. The maximized engines require the premium octane because they were built knowing the higher octane would protect the engine.

Knock Sensors

If you have a newer German car, you may be thinking that you can simply rely on your knock sensor while using a lower octane and all will be well. The knock sensor does help. If the sensor detects knocking, it detunes your German car engine until the knocking ceases. This protects your engine to some extent. Your engine has still taken a beating until the sensor has completed the level of detuning needed. Once the detuning has occurred, your car’s fuel mileage will take a nosedive and your engine performance will suffer as well. In essence, this will negate any savings you may have obtained at the pump.

Ultimately, if you drive a German car, you need a higher octane. Saving a few cents at the pump can cost thousands in engine repair. Avoid the long term cost by using the correct octane for your German car. If your Audi, Porsche, Volkswagen, or BMW needs some TLC or has developed a knocking issue, contact us at Shaus Motorsport and we will take good care of your vehicle.

Are You Using Your Car AC Correctly?

Are You Using Your Car AC CorrectlyAre you using your car AC correctly? With the high heat of summer, Shaus Motorsport in Aurora helps a number of BMW, Volkswagen, Audi, and Porsche owners with their car air conditioning issues. Fixing these issues can be pricey so if you take good care of your AC, you often can avoid a costly repair while easing the strain on your engine and increasing your overall fuel efficiency.

Check out the following guidelines to ensure that the efficiency of your AC is maximized while conserving fuel and saving your engine on your BMW, Volkswagen, Audi, or Porsche.

Take Advantage of Shade

On hot and sunny days, park your vehicle in the shade. This will keep the inside of your car cooler. The cooler your car is when you start driving it again, the easier it will be to make the internal temperature more comfortable at a faster pace. All of this eases the strain on your AC.

Roll Down Your Windows

Take advantage of the sunny day by rolling all your windows down and letting the wind blow through your hair and your car. The internal temps of your car can get much hotter than it is outside. Letting the hot air out before running the air conditioner will help cool the inside of your car faster.

Use a Low Setting to Start

Cranking your air conditioner right away is a good way to wear out your air conditioner faster while straining your engine, and lowering your fuel mileage. Start your air conditioner on low and allow it to run on low for a while before blasting it on a hot day.


Re-circulating your air will help lighten the load on your vehicle’s air conditioning. When you don’t re-circulate, your air conditioner has to work extra to keep you cool. This increases the wear and tear and affects your car’s engine and mileage.

Turn Your AC Off First

When you arrive at your destination, turn your air conditioner off and leave your fan running at medium speed before turning off your car. By doing this, you will help keep your evaporator dry.

Fuel Efficiency

Using your air conditioner lowers the fuel efficiency of your vehicle. The higher you are running the air conditioner, the lower your fuel mileage will be. If you want to save fuel, limit your air conditioner use, lower the level of your air conditioner, and follow our other tips as well.

Get Your AC Serviced Annually

Having your air conditioner checked over regularly will help ensure that it works well on the hottest days of the year. Be sure that your refrigerant levels are checked as well because this is not always included in standard service checks. Use an auto center you trust to service your BMW, Volkswagen, Audi, or Porsche, like Shaus Motorsport in Aurora.

Are you using your car AC correctly? Using the above tips will help you save your AC and your car. If you have a BMW, Audi, Porsche, or Volkswagen AC issue, call us at Shaus Motorsport in Aurora to get your AC working properly.

Getting More Mileage Out of Your BMW

Getting More Mileage Out of Your BMWAt Shaus Motorsport in Aurora, we want to help you with getting more mileage out of your BMW. These vehicles have some of the best performance engines in the world, but it is easy enough to skip some simple steps and not get the most out of your BMW engine. Here are some tips to extend the life of your BMW engine and increase its overall performance.


One of the simplest steps is also the one that often gets skipped. Change your engine oil and engine oil filter regularly. For older engines, changing every 5,000 miles is an excellent schedule to keep. Newer models that use a full synthetic oil can go 7,000 miles between engine oil services. If you are not sure about the oil your engine requires, check your owner’s manual or visit us at Shaus Motorsport in Aurora. If you have an M-Series engine, it is important to only use single weight oil. Do not use variable weight oil as a substitute.

Oil Filter

When it comes to getting more mileage out of your BMW, your vehicle’s oil is crucial. It is important to know that not all oil filters are created equally. A lot of fast lube shops use cheaper paper oil filters. These types of filters can have issues with air restriction and frequent clogging. These cheap filters should be avoided to extend the mileage on your BMW engine.

Pay Attention to Your Cooling System

Make sure that your engine has the coolant it needs and that it has enough of it. Getting more mileage out of your BMW requires proper care and attention to such an important but easily overlooked part of your high-performance vehicle. 

Use a Specialty Shop

Shops that cater to higher end cars and engines, such as Shaus Motorsport in Aurora, are your best bet in keeping you satisfied and your engine running in top shape for a long time. A trained BMW specialist has a much deeper level of understanding and a visual inspection of your engine will give them the opportunity to catch issues early, long before the issue becomes a costly repair or leaves you in a tough spot with a car that won’t start.

Pay Attention to Your Check Engine Light

Though there are many, many reasons that your check engine light comes on while driving, do not be the driver who ignores it. There are three main reasons that prompt the light to come on: fuel distribution and flow, air distribution and flow, and spark delivery to the combustion chamber. Some reasons can be quite simple like your gas cap isn’t sealing properly, but some can be an indicator of a much more serious problem. Ignoring the light can cause your engine serious damage and can put a serious dent in your wallet.

At Shaus Motorsport in Aurora, we want you to know whether you are getting more miles out of your BMW. These simple steps are a good start to extending the life of your engine. If you want more help and tips to keep your engine in top shape, contact us a Shaus Motorsport in Aurora.

Tips for Proper Audi Maintenance

Tips for Proper Audi MaintenanceToday, our experts at Shaus Motorsport in Aurora want to provide you with helpful tips for proper Audi maintenance. Although much of what keeps your Audi running smooth has to do with the design and build of this great car, proper care and maintenance are required to keep it in tip-top shape so you can enjoy all the features it has to offer.

It Starts with the Engine

If you want to make sure that you don’t have any timing belt issues, have the necessary parts changed while the belt in your Audi is serviced. This makes it easier because the components are already being accessed, making them readily available. The items that you may want to consider replacing include o-rings, seals, the snub mount, and the Loctite thread locking components.

Another helpful item to check off your list is to determine if your water pump may be leaking. The easiest way to do this is to remove the splash pan. You will notice a coolant trail between the lowest spot on the engine and the pump if the water pump is leaking.

Brake Maintenance

One of our most important tips for proper Audi maintenance is to make sure you’re brakes are road ready. Brake fluids need to be changed every 3 years or 30,000 miles, whichever time frame occurs first. If you want to save yourself money, hassle, and time, change the fluids at the same time you are having the brake pads or rotor replaced.

Heed the Audi brake pad warning light. It will indicate that the front rotors and/or brakes should be replaced. The warning light illuminates when this maintenance needs to happen in the next 3,000 miles. There is no sensor for the rear brakes, but if you feel a vibration while braking or hear a metal on metal sound when using the brake, then the rear brakes are in need of repair.

Suspension and Steering

If you want to determine whether your wheel bearing is in need of replacement, listen for a change in the humming pitch while your Audi is running at different speeds. If you hear a low humming when driving between 25-35 mph which shifts to a higher pitch when traveling faster, then your wheel bearing may need to be replaced. The faster the speed, the higher the pitch.

If you are experiencing handling issues, you will want to check your ball joints. They may need to be replaced immediately. The ball joints should be checked yearly regardless of how your Audi is handling. Changing your power steering fluid every 30,000 miles, particularly in hot climates, will help prevent hydraulic issues and potential damage to the components.

Driveline and Transmission

If you experience difficulty shifting, have the transmission fluid and filter replaced. This may resolve the issue. Transmission fluid should be replaced every 30,000-60,000 miles. Instead of replacing the entire drive shaft as part of your maintenance routine or if you are experiencing issues, you may be able to have only the outer CV joints replaced. The inner CV joints typically don’t wear very much.

Now that you have some great tips for proper Audi maintenance, be sure to contact us at Shaus Motorsport in Aurora for your next maintenance or repair service. We would be happy to help you keep your Audi running smoothly.

Common Problems if You Own a Porsche

Common Problems if You Own a PorscheTo help you be a better Porsche owner, here is a list of common problems if you own a Porsche from the experts Shaus Motorsport in Aurora. Because we specialize in servicing elite brands like Porsche and BMW, we know how important it is for an owner of such refined machinery to be familiar with their vehicles, both the good and the not so good. Luckily, if you experience any of these issues, you can certainly bring your vehicle to the shop for VIP repairs.

Burning Oil/Oil Leaks

On Porsche vehicles oil leaks can stem from a number of common sources. Valve cover gaskets are common sources, as are spark plug seals. The most frequent sources is also the most potentially destructive one: the rear main seal. In the center of the engine trans area a leaking main seal will be apparent. If a leak is occurring there, it will destroy the clutch in a manual vehicle very quickly.

Vehicles that are often stored away, such as Porsches will develop the leak during storage or during the initial start-up following a storage period. The heat of driving maintains the efficiency of the seal and in some instances, the leak will slow but still can do major damage. The downside is that the transmission must be removed to replace the seal when you bring your Porsche in for repair. It’s a tricky task.

No or Low Battery Power

When a car, like a Porsche, is not driven as much as it could be, no or low battery power can become an issue. Vehicles continue to use some battery power during storage and some, such as the Porsche, use more than expected. Losing battery power completely can cause additional annoyance and headaches because it resets multiple systems. You can avoid this issue by using a battery maintainer any time you will not be driving the car for two or more weeks.

Check Engine Light

There can be a number of different reasons that the check engine light goes on in a Porsche. One of the most commons issues for a 6-cylinder is a problem in the MAF and O2 systems. Often the front O2 sensors fail and will cause the MAF to endeavor to compensate for the failure. Frequently, only the O2 sensors will be replaced but within a couple hundred miles or so, the check engine light will be back on. The reason will be that the MAF is now failing as well. We, at Shaus Motorsports, will generally recommend replacing both the O2 sensors and the MAF at the same time to avoid this issue.

Heavy Clutch Pedal on Your Turbo 911

In 911 Turbo Porsches, the clutch pedal can become heavy. If this is the case, it is likely that the cause may be the pressure accumulator. This device is designed to maintain the necessary hydraulic pressure to operate the clutch after the engine stops. Often, the device will not function prior to startup because it is leaking pressure back into the system. If the accumulator has failed, the slave cylinder is also frequently harmed and may also need to be replaced. If the slave cylinder is fine, expect that its lifespan has probably been shortened by this problem.

Recognizing some of the common problems if you own a Porsche will allow you to spot them earlier and in some cases prevent them. If you end up experiencing one of the above issues or if you have a different problem with your Porsche, contact us at Shaus Motorsport in Aurora and we can get your Porsche issue fixed quickly and to our high standards.

What Goes Into Rebuilding a Turbocharger?

What Goes Into Rebuilding a TurbochargerAt Shaus Motorsports in Aurora our customers often want to know more about what goes into rebuilding a turbocharger and why they should consider having their turbocharger rebuilt rather than simply buying a new one. Today, we’ll cover the information you need to know to better understand more about turbochargers, rebuilding them, and why you might want to consider having this done by our trained experts.

The General Process

First and foremost, rebuilding a turbocharger helps us understand why your turbo failed and this is an important piece of knowledge. When we take a turbocharger apart, we find out a number details about the general condition of the parts, the appearance, as well as the wear on various internal components. We also learn about your driving habits, how well the oil you use is really functioning for your vehicle, and how your maintenance schedule is working or not working for your turbocharger.

One of the details that pleases people the most, is that a rebuild will save you a great deal of money. The average rebuild can cost around less than half of what a new turbocharger might cost. The extra savings is usually well worth the added time that a rebuild can take. Although, at Shaus Motorsports in Aurora, we can often rebuild your turbocharger in a day if we have all the parts available. Give us a call if you’re interested, and we’ll get you all the details.

What happens during a turbocharger rebuild?

  1. First, the turbo is taken apart and thoroughly inspected. New seals, gaskets, and bearings are usually part of putting the turbocharger back together.
  2. Clearances, including bearing and seal journals, housing bores, wheel dimensions, collars, seals, and bearings, are all usually measured.
  3. A careful balancing procedure, including checking, correcting, and rechecking is performed to rectify imbalances that inevitably occur when the new thrust collar assembly is installed.
  4. All the parts are very thoroughly cleaned. Every tiny detail matters in a precision device like a turbocharger. Small amounts of dirt or carbon, even a speck, can cause quick and severe damage, which will reduce the life of your rebuilt turbo.
  5. Every bolthole, fitting, thread, and gasket surface is carefully inspected to ensure it is in proper working order. Any damaged hardware is replaced and all fittings are sealed to ensure your turbocharger will be trouble free upon installation.


Some shops will rebuild your turbo and install it. At Shaus Motorsports in Aurora, we also accept shipped turbos for rebuild, and upon completion, we will mail it back to you or you can pick it up at our shop. Hopefully, this overview of a turbocharger rebuild helps you better understand what goes into rebuilding a turbocharger and why having one rebuilt is probably the best option available. The precision and care put into a rebuild can give you the same results as a new turbocharger for a better price. And in the end, we may have recommendations to further extend the life of your turbocharger to keep both you and your vehicle happy.

When It Comes to the New BMW 5 Series, It’s All in the Details

When It Comes to the New BMW 5 Series, It’s All in the DetailsBMW repair is a specialty at Shaus Motorsport in Aurora, so we know when it comes to the new BMW 5 Series, it’s all in the details. It’s currently BMW’s second best-selling model, right after the 3 Series. This is impressive since passenger cars compose only 39 percent of the market last year, which was actually down from 43 percent in 2015 and 52 percent in 2012.

According to a Good Car Bad Car article, the BMW 5 Series comes in at number 52 in the 2016 year end rankings of all cars.

We can understand why so many people like them. According to a BMW article, the Series 5 is built with lightweight high-strength magnesium, aluminum, and steel, and can go from 0-60 in 4.7 seconds in the 540i xDrive Sedan. It has maximum stability, higher efficiency, and improved handling. The improved chassis optimizes the weight distribution. Improvements to the steering give you precise feedback.

The 5 Series is the seventh-generation version of this six-cylinder 335-horsepower sedan, codenamed G30, and has withstood the test of time.

The Technology

According to a Bloomberg review, BMW a German luxury vehicle manufacturer has proven to offer superior chassis, suspension, and handling. The BMW article describes the available Adaptive Mode intuitively adjusts to your driving style and the road conditions. It can anticipate curves, crossroads, and street types.

This year’s BMW 5 Series offers a surround view system with 3D view exterior cameras. The system uses four cameras that work together to create three-dimensional views of the space surrounding the vehicle. Standard versions of the 5 Series start near $56,000 but with upgrades go up t $82,000 or more. The BMW article says the Active Lane Keeping Assistant uses camera sensors to detect lane markings and keep your vehicle in the lane’s center.

The Bloomberg review says the cameras in the 5 Series are better thought-out in how they show the car and its surroundings. The screens are clearer. The angles of the camera shots are better and built with the driver in mind. The technology is displayed on a new, 10.3-inch display touchscreen that syncs with features that you can control with buttons on the steering wheel and center console. It’s also sensitive to voice commands and hand gestures, and even the top of the iDrive knob, which has a touchpad on it. According to BMW, the Series 5 is the first BMW’s to have iDrive 6.0, which feeds you live content and understands natural speech patterns to answer your commands. It has Optional Gesture Control, which allows you to use simple hand gestures to control navigation, communication, and entertainment. This lets you stay focused on driving.

The 540i comes with adaptive LED headlights and LED fog lights, with chrome-lined exterior trim.

The Bloomberg review points out, “This is perhaps the best setup in the game, not because it’s revolutionary, but because it executes the little things well. (It’s the system BMW’s Rolls-Royce subsidiary also uses.) BMW excels at painstaking attention to details that add up making this sedan striking in a sea of ho-hum contenders.”

The Design

Let’s take a look at the design of the 5 Series. According to the Bloomberg review, “the crenellations on the hood are slightly pinched compared with previous models, making it look just a bit leaner; the way the body is made of high-strength steel, magnesium, and aluminum, which means it’s lighter and stronger than products made from mere aluminum and steel.” 

The car’s remote key fob is large but it can park the car into a spot remotely while the driver stands outside the car. This comes in handy when you have to park in tight spaces in garages or on city streets. It costs $750 and is offered just in the 5 Series cars.

More details include a new design this year which is an etch along the lower part of the sides. The Bloomberg review notices, “the door height and handles are positioned and weighted for perfect entry.”

The adaptive larger LED lights complement slightly larger kidney grilles that have automatic shutters for the first time, helping move air around the car for improved aerodynamics and therefore, improved efficiency. The Bloomberg review concludes, “the 5 Series as a whole, with its structured body and bulging hood, is the more chiseled option in the segment.”

The Interior

The details of the interior should be mentioned. The 540i has an improved soft-close automatic doors. The Dakota leather trim is richer and softer. The rear-view mirror gently auto-dims when the car turns off. BMW describes the 5 Series exterior as sporty and the interior as elegant with Ambience Lighting and available premium Nappa Leather.

The new, optional, ergonomic seat can inflate to change from bucket-style racing seats to comfortable loungers. One option is 40/20/40 split-down rear seats and load-through capability to the trunk. The rear of the 540i is roomy and seats three adults.

The Bloomberg review says, the full-color, heads-up display is clearer and 75 percent larger than in previous generations. The controls on the center console, rest squarely around the center dial, which is big, easy to use, and clearly labeled. The 540i comes with rain-sensing wipers and a two-way glass moonroof. Connected to the cloud, BMW reports the Intelligent Voice Control gets smarter the more you use it by continually analyzing speech patterns for improved quality and reliability.

Drive: Every Little Improvement Helps

The Bloomberg review describes driving the 540i, saying it “provides a lesson in proper German engineering. As it picks up from the lower of its eight gears to topping out in sport mode, the balance of the car’s lighter weight (BMW claims to have shaved 137 pounds from previous models) and renewed connection on its now-standard run-flat tires harmonize beautifully, better than in previous years. Why? We now have an upgraded dynamic handling package and an M Sport package ($2,600) that is lowered. We also have a newly stiffened suspension; adaptive drive mode, which automatically adjusts the electric power steering and automatic transmission to your driving style and road conditions; and optional integral active steering, which combines rear-wheel steering with variable-ratio steering up front. That means the steering becomes quicker the more you wind the wheel, even as it remains consistent in velocity. This all makes for a more predictable car. Predictable, yes. But not boring.”

It’s easy to see why BMW has been making the popular 5 Series since 1972 because when it comes to the new BMW 5 Series, it’s all in the details. BMW repairs and maintenance is one of our specialties, so for all of your BMW repairs and maintenance, bring your vehicle into our BMW auto experts at Shaus Motorsport in Aurora.

10 Things You Should Know About German Auto Repair

10 Things You Should Know About German Auto RepairIf you have a German-made vehicle, Shaus Motorsport in Aurora is here to share 10 things you should know about German auto repair and of course, why it’s important to only bring your car to our German car experts. We believe that customers need to see what goes into maintaining, repairing, and even upgrading their BMW, Volkswagen, Audi or Porsche. Because German cars are our only focus, we are uniquely poised to share our passion with you by providing both the information you need to know and the specialized services required for your German vehicle.

Now, here are 10 things you should know about German auto repair and why you need a shop that specializes in German-made cars for auto repair and maintenance.

  1. Special skill and experience

German manufactured vehicles are not like other cars. They are engineered for performance. To maintain and repair them takes special tools and expensive diagnostic equipment which are specific to your make, model, and brand. Most car repair shops do not have the expertise to properly service your German performance vehicle. They won’t be able to diagnose your car’s problems accurately and offer the correct repair. But Shaus Motorsport specializes in these cars and we can get you in and out with the right repairs and maintenance.

  1. Complex electronics and computers

German cars have very complex electronics and computers, with many having 30 or more on-board computers and control modules. Some models even have almost 90 electronic control units. The braking systems, steering, transmission, throttle, and engine management are all interconnected in your vehicle. These modules need to be checked and updated from time to time as suggested by the manufacturer service bulletins. To fix these highly sophisticated cars it takes very specialize diagnostic equipment and not too many shops have that capability.

  1. Clean drains

Some German-made vehicles have sunroofs with a series of drains running from the sunroof through the vehicle body and out underneath the car. You need to clean the drains because if they get clogged, they will back up and possibly flood the interior of your car. If it floods, besides the mess, the sensitive electronics under your seats could be damaged and that could lead to more expensive repairs.

  1. German-made parts

When your car needs parts you want to make sure you get original manufacturer parts. Not every shop has access to those and very few have them available. You need experts like our technicians at Shaus Motorsport who know what works the best for your vehicle and how to get the correct parts, whether for repairs or performance upgrades

  1. A spare key

We recommend you get a spare key for your German-made car because when an electronic key stops working, it leaves the vehicle immobilized. The price of another key is well worth the security of knowing you will not be stranded with a car that you can’t drive. This is particularly true for later model BMW, Volkswagen, Audi, and Porsche because they have security chips that connect the key to the car. So when you key dies your vehicle will not be able to move.

  1. Scheduled maintenance

BMW, Volkswagen, Audi, and Porsche vehicles are programmed to let you know when services need to be done, like an oil change, air filters, brake fluid, and brake pads, among others.

But to read service codes and reset them after the service is done takes specialized factory diagnostic equipment.

Our technicians at Shaus Motorsport know the special requirements for German-made cars, like the recommendation to change the oil every 5,000 miles for turbo and supercharged engines like the 1.8T, 2.0T in VW and Audi and every 7,500 for all other late models.

Other than vehicles with mechanical lifter designs, like the BMW M-series which requires 60-weight oil, and TDI diesel engines, Mobil 1 0W/40 engine oil is best for most German-manufactured makes and later models.

We know that TDI diesel engines require specific engine oil that should not be mixed and older models that use mineral based oil should not use full synthetic oil. We always follow the manufacturer recommendation for oil viscosity.

  1. Tires  

Several German-made vehicles like BMW, Volkswagen, Audi, and Porsche all use limited slip differentials. If you drive an Audi A6 Quattro or a Porsche 4S, your tires need to be matched in circumference. A  2/32 inch (2 cm) tread depth difference between tires on the same axle can create rotational speed variances that will cause trouble with the car’s drive train management systems.  

You should never use mismatched tires on the same axle and on the 4-wheel drive systems such as the Audi Quattro. All four must be circumference matched within 2/32 inch (2cm). Remember tire wear will affect the circumference of a tire, so they should be of the same age. So that means tires on the same axle should be replaced at the same time and in the case of the Quattro systems, that means all four tires should be replaced together.

  1. Air filter

Shaus technicians recommend replacing your cabin micro air filter every 40,000 miles as the manufacturer suggests. Some people overlook the cabin air filter but it is important because in addition to keeping the air clean to breathe, sometimes a filter that is not working can cause the blower motor to work overtime and damage the motor and the blow motor resistor.

  1. Brake fluid

Your German-manufactured vehicle’s brake fluid attracts moisture, so you need to change your vehicle’s brake fluid at least every two years. Many late model German vehicles will give you a service code reminder.
