We’ll discuss the benefits of performing this reset and explain what a TCM is in this comprehensive guide.
This article will provide you with the knowledge and steps you need to reset the transmission control module on your Audi A1, A3, A5, A6, A7, A8, Q3, or Q5.
TCM stands for Transmission Control Module
My experience with Audis for many years has taught me that many Audi owners experience transmission problems such as jerking, stuttering, or delayed gear changes.
When things go wrong with your car, you may feel frustrated and believe that expensive repairs are needed.
The transmission control module, also known as the gearbox computer, can affect your Audi’s performance in many cases by resetting it.
Among the most crucial components of your Audi’s gearbox system, the Transmission Control Module (TCM), is the transmission control module. In addition to monitoring and controlling the transmission’s operating parameters, it is also responsible for:
- Gear shifts
- Shift timing
- Shift quality
- Clutch engagement in torque converters
- Adaptive shifting
TCMs receive information from various sensors throughout the vehicle, including throttle position sensors, engine speed sensors, and vehicle speed sensors.
On the basis of driving conditions and driver input, the system selects the optimal gears and shift points.
What are the benefits of resetting your Audi’s TCM?
When your Audi’s TCM accumulates data, it can lead to problems with transmission or performance.
When you reset the TCM, you’re going to get smoother, more responsive gear changes, because any stored error codes get cleared out.
Here are some symptoms that might indicate you need to reset your Audi’s TCM:
- During gear changes, the vehicle jerks or stutters
- Engagement of the gears is delayed
- Shifts that are hard or rough
- Slipping of the transmission
- Fault-safe or limp mode
TCM Reset Methods for Audis
Resetting the transmission control module of your Audi can be achieved in three ways:
- Method 1: Manually reset the device by pressing the gas pedal

Method 2: Using an OBD Scanner
The following steps can help you reset Audi’s TCM with the help of an OBD scanner:
- Located under the dashboard on the driver’s side is a diagnostic port that you can connect the OBD scanner to.
- The ignition should be turned on
- You can find this menu on your scanner by going to Transmission Control Unit
- You can reset or relearn by selecting the “Reset” or “Relearn” option

Method 3: Battery Disconnect Method
This method resets all Audi control modules, including the TCM, by disconnecting the battery. This reset can be performed by following these steps:
- Consult your owner’s manual if you need help finding your vehicle’s battery.
- By using a wrench, you should be able to remove the negative terminal of the battery
- To ensure that the system is fully discharged, wait 15-30 minutes
