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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
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.
- 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.
- 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.
