RS6 Transmission Nightmare: Grinding Gears & Limp Mode

Having worked on a similar issue with my 2015 RS7, I can share my experience as someone with some hands-on repair knowledge. The symptoms you describe match exactly what I encountered, transmission fault warnings, rough shifting, and that concerning grinding noise. Initially, I also thought it was a transmission sensor issue, but it turned out the transmission oil level was critically low, triggering the pressure switch warnings. The workshop found that low oil pressure was causing the transmission to protect itself by going into limp mode. The fix involved: Complete transmission oil level check, Replacement of transmission oil, Clearing fault codes, Test drive to confirm proper shifting Total cost was 365 Euro, including parts and labor. The repair resolved all symptoms completely. Before jumping to sensor replacement, it would be helpful to know: Current mileage on your RS6? When was the last transmission service performed? Are you noticing any oil spots under the car? Does the grinding noise happen at specific speeds? This could help determine if you are facing the same root cause or if there might be other issues at play.

I had 42255 KM on the clock when this happened. The transmission sensor replacement did fix all my problems. The pressure switch was faulty and caused incorrect readings, making the transmission control unit act up. A professional mechanic replaced the transmission oil pressure sensor for 425 Euro including labor. No transmission issues since the repair. Would recommend others faced with similar symptoms to have their pressure sensor checked first before assuming worst-case scenarios. The diagnostic showed a clear correlation between the sensor malfunction and the transmission problems experienced. Got it fixed during my last annual service and glad I acted quickly before any major damage occurred.

Glad to hear the pressure sensor replacement resolved your transmission issues. My experience with my RS7 taught me these transmission fault warnings can be nerve-wracking, but often have straightforward solutions. Since fixing my initial oil pressure problems, I did a few preventive steps to avoid future transmission issues: Regular transmission fluid checks, Monitoring for any unusual shifting behavior, Keeping an eye on sensor-related fault codes The sensor fault diagnosis in your case matches what many owners experience, faulty readings from a bad pressure sensor causing the transmission control unit to act erratically. The 425 Euro repair cost seems in line with typical sensor replacement pricing. Quick action definitely helps prevent more serious transmission damage. These modern gearboxes are quite good at protecting themselves when they detect pressure irregularities, which is why they go into limp mode. For documentation purposes, can you share if the grinding noise completely disappeared after the sensor replacement? This info could help others troubleshoot similar symptoms.

Thanks for the update regarding the pressure sensor replacement. The 425 Euro repair cost was definitely worth avoiding potential transmission damage. My oil pressure sensor started showing similar symptoms at around 40000 KM, so the timing matches up. The grinding noise disappeared completely after the repair. The transmission sensor replacement fixed all symptoms, no more limp mode, rough shifting, or warning lights. The pressure switch was definitely the root cause, sending incorrect readings to the transmission control unit. Worth noting for others that while my annual service was due anyway, I scheduled an urgent appointment when these symptoms appeared. Acting quickly likely prevented more expensive transmission repairs down the line. Regular maintenance and prompt attention to warning lights really does make a difference in these cars. The diagnostic data clearly showed the sensor fault was causing the transmission issues. Having the repair done professionally with proper diagnostic equipment was key to identifying and fixing the exact problem.
