• Reasons Behind Control Module Failure in Audi

    Audi Control Module

    All cars that are manufactured and engineered these days include control modules, which is really just a fancy word for on-board computer. Most vehicles, including Audi vehicles, utilize various control modules, including these particular types of modules that perform specified functions for your Audi:

    • Electronic
    • Transmission
    • Brake
    • Powertrain
    • Central timing
    • Body
    • Suspension

    All of these control modules work together to create a cohesive, well-functioning vehicle where every system and component is regulated and analyzed routinely and systematically. One of the primary, and most important, control modules in your Audi is the powertrain control module (PCM), which is commonly referred to as the engine control unit.

    Since Audi vehicles are designed with luxury and performance in mind, control modules – especially the PCM – play an integral role in the vehicle’s longevity, consistency, and reliability. If any of the aforementioned control modules fail, you’ll begin noticing complications with your Audi’s performance, usually immediately. In this article, we’ll discuss why control modules are so important and what you should be aware of should they fail or malfunction.

    Why are Control Modules so Important?

    Your powertrain control module is what keeps all of the various components working in harmony together. Equipped with sensors, fuses, and electrical connections such as wiring, all of the car’s control modules communicate to provide the car with accurate information, which helps it adjust to various driving conditions and the driver’s individual driving habits. Acceleration, braking, steering, and fuel consumption are just a few facets that are regulated by control modules. The powertrain control module is what helps to alert the driver if any of these systems or components aren’t working properly through the dashboard warning lights.

    Possible Causes of Control Module Failure

    The variety of control modules in your Audi work because they are powered with electrical current; if one fails, it’s likely due to one of the following power issues:

    • Not enough power supply or voltage is being directed to the module
    • Too much voltage is being directed to the module
    • Disintegrated connections between modules
    • Failing sensors
    • Especially high engine temperatures
    • Exposure to water or too much moisture
    • Extreme engine conditions such as intense vibration

    Now that you know generally what can cause control module failure, it is important to take steps to proactively protect your various control modules from experiencing failure or malfunction – this will ensure your vehicle’s reliability, longevity, and performance, but most importantly, will keep your hard-earned money in your pocket instead of being spent on unnecessary repairs.

    Signs that May Indicate Control Module Failure

    One way to prevent issues from arising with your PCM or other control modules is to be aware of any changes in your vehicle’s performance. These are some of the most common alerts of control module failure.

    • Fuel efficiency changes
    • Uneven or difficult acceleration
    • Hiccups in engine timing
    • Misfiring or stalling
    • Dashboard warnings illuminated (especially the check-engine light)

    While these are common signs of control module failure, especially the PCM, these symptoms can also occur as a result of an issue with another system or component in your Audi. Therefore, it is important to follow up with any changes in your Audi’s behavior quickly in order to rule-out other potential causes of the concerning symptoms.

    What to Know About Your Audi

    Audi vehicles can be prone to control module failure due to electrical connection deterioration. It is important to follow through with the following maintenance tips to ensure your Audi continues to function well over time:

    • Have wiring harnesses checked out routinely
    • Inspect fuses regularly
    • Follow your Audi’s individual maintenance plan recommended by the manufacturer (you can find this information in your owner’s manual)
