Here’s a look at some of our electronic services:

Cloning of Used Control Units

When Needed

The control unit is essentially the vehicle’s computer, responsible for managing various functions, from engine operation to the air conditioning system. When your German car’s control unit starts to fail, it can lead to a range of issues, impacting both performance and safety.

Purchasing a new control unit, especially for German vehicles, can be incredibly expensive, and sometimes, there might be availability issues due to model discontinuation or supply chain problems. That’s where cloning comes into play.

Cloning means we take a used control unit from a similar vehicle and program it with your car’s specific data and configurations. This process ensures that the replacement will work seamlessly with your car’s system, just like the original.
Cloning is also about reliability and maintaining the high quality of service we stand for. We make sure that your German vehicle continues to run smoothly, with all systems operational, while extending the life of your car.

Resetting BMW

Footwell Modules

The footwell module, commonly referred to as the FRM in your BMW, is a vital component that controls the lighting, window, and door functions. Just like any sophisticated piece of technology, sometimes it needs a reset.

Why would we reset your BMW’s FRM? It could be due to a minor glitch after a battery drain or replacement, or it may stem from software updates. Resetting the FRM is like giving your vehicle’s electrical system a fresh start. It ensures that all the settings are correctly aligned with your car’s operational blueprint, maintaining the luxury and functionality you expect from a BMW.

Module and Control

Unit Repair

The instrument cluster is your dashboard, the direct line of communication between your car and you. It displays vital information like speed, fuel level, and engine warnings. If there’s an issue here, it could lead to misreadings or a complete blackout of crucial data. Repairing the instrument cluster ensures you’re always accurately informed about your car’s status.


The Engine Control Unit is the brain of your car. It oversees engine performance, ensuring optimal fuel efficiency and emissions control. A malfunctioning ECU can lead to decreased performance, increased emissions, or even engine failure. Timely repairs prevent these issues, keeping your car running smoothly.


The ABS control unit manages the anti-lock braking system, a key safety feature, especially in slippery conditions. If this unit fails, you might lose crucial braking capabilities when you need them most. Repairing this unit ensures your safety on the road.

Additionally, various sensors throughout your vehicle, like oxygen sensors or temperature sensors, play a vital role. They feed information to the ECU to manage engine performance, emissions, and more. Faulty sensors can lead to incorrect data being fed to the ECU, resulting in poor performance or even damage.

CIS Injection

Component Repair

CIS, or Continuous Injection System, is a type of fuel injection commonly found in vintage and classic German cars. It regulates the flow of fuel to the engine, ensuring that your vehicle runs smoothly and efficiently. Over time, components in the CIS system can wear out or become clogged, which can lead to a range of issues like poor idling, stalling, or even reduced fuel efficiency.

Repairing the CIS injection components is crucial because it helps to maintain the optimal performance of your vehicle. When these components are not functioning properly, your car might not run as smoothly, it could use more fuel than necessary, and in some cases, it might not run at all. By addressing these problems early, we can help prevent more significant issues down the line, ensuring that your vehicle remains reliable and enjoyable to drive.
At Hans Wittler’s Automotive, we specialize in the intricacies of German-engineered systems, and we understand the importance of precise fuel delivery. We take great care to diagnose and repair any issues with the CIS injection system, using our expertise to ensure that every component works as intended. This not only keeps your vehicle performing at its best but also aligns with our goal of reducing the overall cost of vehicle ownership through preventative maintenance.

Maintaining your CIS injection system isn’t just about immediate benefits; it’s also an investment in the longevity and reliability of your classic German car. We’re here to provide you with high-quality work and exceptional service, just as we have been doing since 1975.

Mileage Correction On

Used Instrument Clusters

Your vehicle’s instrument cluster is the panel in front of the driver that displays important information, including the odometer reading, which shows how many miles your car has traveled. 

When the instrument cluster is damaged or malfunctioning, we may replace it with a used cluster as a cost-effective solution. However, the replacement cluster will often display the mileage from its original vehicle, not yours.

Here’s where mileage correction comes in. It’s important for the odometer reading to reflect the true mileage of your vehicle for a number of reasons. 

Firstly, accuracy in your car’s mileage is essential for understanding its wear and tear, helping us make informed decisions about maintenance and preventative care. Secondly, it ensures that you have a reliable record for resale value, as potential buyers will want to know the actual mileage. Lastly, it’s a legal requirement; the displayed mileage must be correct to avoid fraud.
