The 01M transmission, a popular automatic transmission used in various Volkswagen Audi Group (VAG) vehicles, is known for its smooth shifting and reliability. However, like any other complex automotive system, it can sometimes require a reset. This is where VCDS (Vag-Com Diagnostic System), a powerful diagnostic software, comes in. This article will delve into the process of performing an 01M transmission reset using VCDS.
Understanding the 01M Transmission Reset
A transmission reset using VCDS involves clearing the transmission control module’s (TCM) adaptive memory. This memory stores driving style data and adapts the transmission’s shift patterns accordingly. Over time, this data can accumulate, leading to less-than-ideal shifting behavior. Resetting the TCM erases this data, forcing the transmission to relearn your driving style and potentially resolve minor shifting issues.
When is an 01M Reset Necessary?
Several scenarios might call for an 01M transmission reset:
- Rough Shifting: If you experience jerky or delayed shifts, especially after replacing transmission fluid or components, a reset might smooth things out.
- Fault Codes: After addressing a transmission-related fault code, a reset is often necessary to clear the code from the TCM’s memory.
- Software Updates: Following a TCM software update, a reset ensures the transmission operates correctly with the new software.
VCDS Software Interface
Performing an 01M Transmission Reset Using VCDS
Before you begin, ensure you have a genuine VCDS interface and the latest version of the software installed on your computer.
Step-by-Step Guide:
- Connect VCDS: Connect the VCDS interface to your vehicle’s OBD-II port and your computer.
- Turn On Ignition: Turn the ignition on, but do not start the engine.
- Launch VCDS: Open the VCDS software on your computer.
- Select Control Module: Select “Select Control Module” from the main menu.
- Choose Transmission: Navigate to “02 – Auto Trans” or “01 – Engine,” depending on your vehicle model.
- Basic Settings: Go to “Basic Settings – 04.”
- Select Reset: Depending on your specific model, you’ll find an option like “Reset Transmission Adaptation” or “Adapt Throttle Position.” Select the appropriate option.
- Follow On-Screen Instructions: Follow the prompts provided by VCDS. This usually involves cycling the ignition or pressing the accelerator pedal at certain points.
- Complete Reset: Once the process is complete, VCDS will confirm the reset.
- Clear Fault Codes (If Any): After the reset, check for any remaining fault codes and clear them if necessary.

Note: The exact steps and menu options might slightly vary depending on your vehicle’s model year and specific TCM. Always refer to your vehicle’s service manual or the Ross-Tech wiki (VCDS manufacturer) for precise instructions.
Important Notes and Considerations
- Battery Voltage: Ensure your vehicle’s battery is fully charged before starting the reset procedure to avoid interruptions.
- Professional Help: If you are uncomfortable performing this procedure yourself, it’s always best to consult a qualified automotive technician specializing in VAG vehicles.
Frequently Asked Questions
Q: Will a reset fix all my transmission problems?
A: While a reset can resolve some issues, it’s not a guaranteed fix for all transmission problems. Serious mechanical or electrical faults will require professional diagnosis and repair.
Q: How often should I reset my 01M transmission?
A: It’s not necessary to reset your transmission regularly. Only perform a reset if you experience shifting problems or after addressing transmission-related repairs or software updates.
Q: Can I use any OBD-II scanner for this reset?
A: No, a generic OBD-II scanner cannot perform this specific reset. You need a dedicated diagnostic tool like VCDS, specifically designed for VAG vehicles.
Mechanic Working on Car Transmission
“The 01M transmission is a robust system, but like any technology, it benefits from a periodic ‘refresh.’ Performing a reset with VCDS is a relatively straightforward procedure that can often restore smooth shifting and clear up minor glitches,” says Mark Williams, a veteran automotive electronics specialist and author of “The Automotive Technician’s Guide to Electronics and Control Systems.”
Conclusion
An 01M transmission reset using VCDS is a valuable tool for addressing various shifting issues and ensuring optimal transmission performance in VAG vehicles. By following the steps outlined in this guide and taking necessary precautions, you can perform this procedure yourself. However, if you encounter persistent issues or are uncertain about any aspect of the process, seeking assistance from experienced professionals like those at Cardiagtech is always recommended.
