VW Polo DSG Transmission Failure: Control Module Alert

Had almost identical transmission problems with my 2011 VW Golf DSG. After multiple electronic issues and transmission problems, the diagnostic confirmed a defective control unit. The symptoms matched yours exactly, rough shifting, grinding noises, and the automatic gearbox went into limp mode. The automotive ECU was throwing similar error codes related to the transmission control module. With some experience working on VWs, I first tried basic troubleshooting but quickly realized this was beyond DIY repair territory. Took it to a transmission repair specialist who confirmed the control unit failure. The entire repair including parts and labor came to 1000€. The fix involved replacing the DSG control module and recalibrating the transmission settings. After the repair, the transmission shifted perfectly again and all error codes cleared. To better assist with your specific case, could you share: Current mileage on your Polo, When the symptoms first appeared, Whether the transmission fluid was ever changed, Any previous transmission repairs, Complete error codes from your diagnostic scan This information would help determine if your issue is identical to what I experienced with my Golf.

Just had my 139284km service done last month, but this appears to be a valid transmission diagnosis based on those symptoms. Our DSG issues sound identical. The repair cost paid for the control module replacement plus recalibration seems reasonable at 1000€. The transmission problems started showing right after a cold start, getting progressively worse over 2 weeks. No prior transmission repairs were done except regular DSG fluid changes at recommended intervals. The car computer shows error code P0722 which confirms the transmission control module failure. I will contact a transmission specialist for a proper assessment since DIY repair is not recommended for DSG control units. Thanks for detailed info about your experience.

Good to hear back about your Polo's situation. The P0722 error code on your transmission diagnosis matches exactly what I saw on my Golf before the repair. The fact that your symptoms appeared gradually after cold starts is also consistent with my experience of transmission control unit failure. The regular DSG fluid maintenance you did likely helped prevent more extensive transmission problems. My repair specialist mentioned that proper fluid changes are crucial for these automatic gearbox systems, though they cannot prevent electronic issues in the control module itself. Since replacing my transmission control unit, I have put another 50000km on the car without any recurring transmission problems. The automotive ECU has remained clear of error codes, and the DSG shifts as smoothly as new. Just make sure your transmission specialist has experience specifically with VW DSG units. They will need proper diagnostic equipment to properly recalibrate the new control module after installation. While 1000€ might seem steep, it is much cheaper than replacing the entire transmission. Let us know how the repair goes. A properly diagnosed and fixed DSG control unit should resolve all your current shifting and performance issues.

Thanks for the detailed feedback about your Golf DSG repair experience. Based on your successful fix, I feel more confident proceeding with the transmission control module replacement on my Polo. My transmission specialist confirmed they regularly work on VW DSG units and have the proper diagnostic tools for recalibration. They quoted around 1100€ for parts and labor, which aligns with what you paid. I scheduled the repair for next week since the transmission problems are getting worse. The grinding sounds during shifting are concerning, and I want to prevent any additional damage to the automatic gearbox components. Really appreciate you sharing the long-term outcome, 50000km of trouble-free operation after fixing the control module is reassuring. Will update once my repair is complete, but your experience suggests this should resolve all my current DSG issues and error codes.
