VW & Audi DSG Gearbox ECU

VW Audi mechatronic DSG fault

VW and Audi DSG Gearbox ECU problem (Mechatronic Control Module Fault)


Malfunction of the 6-speed DSG transmission ECU is very common across all Audi and Volkswagen vehicles with this Mechatronic gearbox.

Failure usually begins intermittently with the P R N D S lights flashing and the gearbox dropping into neutral (N) position, worryingly this also happens whilst driving. When parked the gearbox may fail to select forward or reverse gears leaving the vehicle stranded with no way to move it until the vehicle has cooled down.


These faults will always become more permanent with time. When presented with a failure of the 6-speed DSG Mechatronic you may think to replace the part with an expensive new unit from manufacturer as your only option. However, the common faults with these units are inherent and have not been worked-out at manufacturer level. Meaning that short 1-year warranty you get with new will not be sufficient to cover the impending malfunction.

We offer a better solution: we test and rebuild your own unit, keeping all original programming, and work-out the faults present since manufacture level. This will be completed in 2-3 working days and our Lifetime warranty will provide peace of mind, though we expect the rebuilt unit not to fail anyway.



Common Failure symptoms:

  • PRNDS flashing
  • Loss of forward and reverse gears
  • Dropping out of gear while driving
  • No communication to the gearbox ECU


Common fault codes:

  • P0751 17135 – Shift Solenoid 1 (N88) Short To Ground

Test and rebuild:

Our purpose-built Hardware In-the-Loop testing rigs allows us to test these Mechatronic transmission ECUs under real-world load and driving conditions and identify all faults within the unit. Once the DSG transmission ECU has been rebuilt we test these again to ensure that it meets OEM operating standards and that no faults remain. Constant in-house development means that all our testing procedures are as extensive and encompassing as possible.



During testing and rebuild we retain all original programming which means that once the unit is returned it is plug and play.



Our test and rebuild work is world renowned and is used by franchise dealerships and specialists across the globe. Our work defect rate is lower than 0.49% on all our rebuilds, so you can be assured of our very high standard of work.

Hello. I am wondering how much on average you charge to rebuild a dsg gearbox Mechatronics. It is from a 2006 Volkswagen Jetta tdi 1.9. If Id chose to have you test the Mechatronics how much would the test be and if it is bad is that included in the whole price of the rebuild or will there be a separate charge for the text and rebuild?
