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.

  1. Use Shaun Motorsport as a resource

Our technicians are here to answer your questions and give you advice about your German-manufactured vehicle. We’ve given you the first 10 things you should know about German auto repair but we have lots of other suggestions. If you have a BMW, Volkswagen, Audi, or Porsche bring it to our expert technicians at Shaus Motorsport in Aurora. We can give your German car the specialized maintenance and repairs that it needs.

Why VW Diesel Buyback Pays Owners to Keep Their Cars for Two More Years

Why VW Diesel Buyback Pays Owners to Keep Their Cars for Two More YearsAt Shaus Motorsport in Aurora, we are Denver’s German auto repair professionals. There’s been some confusion lately regarding the VW emissions problem, so we want to explain why the VW diesel buyback pays owners to keep their cars for two more years.

Volkswagen plans to make buyback offers later this year. The buybacks will be available to more than 450,000 owners of Volkswagen and Audi sedans, wagons, and hatchbacks with 2.0-liter TDI diesel engines. This is for model years 2009 through 2015.

Many owners plan to take the buyout, but financially, it might be better to wait until the last possible moment to accept the buyback.

So when Volkswagen rolls out its anticipated offer to either correct the TDI emissions problem or buy back the car, many people already know what they want to do. Many plan to take the buyback as soon as they can. But all TDI owners should consider an interesting financial component in Volkswagen’s settlement with the EPA, CARB, and class-action attorneys.

Under the settlement, Volkswagen must buy or fix the affected TDIs by the end of 2018. According to a Green Car Reports article, this gives owners a two-year window of opportunity to end up with more money out of the deal. 

Here’s how it works.

At year-end 2016, let’s say a 2012 TDI has accumulated 110,000 miles and a 2015 TDI has 30,000 miles. Under the settlement agreement, Volkswagen would buy back the 2012 TDI for a total of $18,287 and the 2015 TDI for $22,776.

But what would it look like for a buyback two years later at the end of 2018?

At that time the 2012 TDIs odometer has 154,000 miles and the 2015 shows 74,000 miles. At the end of 2018, Volkswagen would then buy back the 2012 for $17,417 and the 2015 for $21,636.

Although the 2018 buyback would pay $870 less for the 2012 TDI and $1,140 less for the 2015 TDI than the 2016 buyback, they would each be two years older and have 44,000 more miles on the cars.

Green Car Reports estimates that the cost of waiting two years to take the buyout would be $36.25 a month for the 2012, and $47.50 a month for the 2015.

This means it would benefit the owners to hold on to and drive their TDIs until the last possible moment and then take the buyback, because the buyback amount is frozen at the car’s clean trade-in value as of September 2015. It does not decrease with either time or miles unless mileage exceeds 12,500 per year.

Yes, you will still have to pay the interest, insurance, maintenance, and fuel, but you would have to pay those on a replacement vehicle, too.

This explains why the VW diesel buyback pays owners to keep their cars for two more years. As Denver’s German auto repair professionals, Shaus Motorsport in Aurora will not only provide professional repairs and maintenance but all the important news you need to know about your German vehicles. We’ll let you know if we hear any further updates about the VW buyback. Stay tuned.
