VW and Audi DSG Gearbox ECU problem (Mechatronic Control Module Fault) This is a very common problem for all Volkswagen and Audi vehicles fitted with the DSG (Mechatronic) 6-speed gearbox system. VW had a lot of bad press back then around DSG and few other incidents, and increased the transmission warranty to 5 years. It may or may not apply to your specific vehicle though – depending on the exact year, and when they started and stopped the offer. DSG: if you like to find out how the DSG gearbox works please click the video beside. Explanation and advantage of the feature will be shown in the video.To. DCT transmissions have been used on vehicles sold by Volkswagen, Audi, SEAT, Skoda and Bugatti, mostly marketed using the term Direct-Shift Gearbox (except for Audi, which has also used the term S-Tronic). Usage in high performance cars began in 2005 with the 7-speed DCT used in the Bugatti Veyron.

Special Procedures
Defined Test Drive
Suggested test drive after replacing the mechatronic or successful basic setting.
Prerequisites:
- Fluid Temperature 30...100 °C (86...210 °F), see Measuring Blocks, Group 019.
- Do Not use Cruise Control.
Drive in Tiptronic Mode from stand still up to 6th Gear.
While doing that make sure to drive in Gears 3 or 5 for approx. 5 minutes and also in 4 or 6 for approx. 5 minutes.
The engine speed window for all gears is 1200 - 3500 RPM (for clutch calibration).
Perform one sharp braking followed by a full throttle acceleration (oil return check) while in Drive, Not Tiptronic Mode.
Evaluate creep and starting-off points.
Check for leaks.
NOTE: If the test drive cannot be performed in the recommended way or the necessary time, any remaining adaptations will be performed automatically during normal driving.
Special Notes
- Some modules do not require the use if the [ON/OFF/Next] button. If an Error is displayed after clicking the button, or the Basic Settings status does not switch to On, let the selected group and procedure finish on its own.
- It is normal for the transmission to make noise while the tolerances are adapting. Do not exit or abort the Basic Settings sequence prematurely if you hear clacking noises.
- Customers with TDI's have reported that an RPM range of 2000-2500 rpm is sufficient.
Replacement
Replacement Mechatronic units should be ordered by VIN based on PR Codes to confirm vehicle compatibility.
