Audi TT Engine Mount Vibration Fix & Cost Guide

Had similar issues with a 2015 Audi S3. The symptoms match what could be failing motor mounts, but in my case, it turned out more complex. The engine mount bracket showed severe wear, which allowed excessive movement and led to disconnected wiring harness plugs. The transmission mount was also affected due to the extra stress from the failing engine mount. A complete inspection revealed the mounting bracket needed replacement along with both the engine mount and transmission mount. The mount failure caused the wiring connection issues, triggering error codes and rough idling. This is a serious repair job requiring specialized tools and proper torque specifications. The motor mount system on these engines needs all components working together, when one fails, it typically affects the others. Worth checking all mounting points and electrical connections before replacing parts. Would suggest getting a thorough diagnosis at a shop familiar with VAG engines, focusing on: All engine mount connection points, Wiring harness integrity near the mount areas, Transmission mount condition, Bracket alignment and wear patterns The repair took several hours but resolved all vibration issues and error codes completely.

Thanks for sharing your experience. Your case sounds very similar to what I went through. I had a 2012 TT that developed the exact same symptoms. My initial rubber mount replacement turned into a bigger job when they discovered the mounting bracket had also cracked, likely from the prolonged stress of the failed mount. Just wondering, do you remember roughly what the total repair cost was in your case? And have you experienced any related issues since the fix? My repair was about 6 months ago and everything has been smooth, but I keep checking for any signs of mount wear since the first failure caught me off guard.

The total job came to 95 Euro for fixing the cable and plug connection issue. Much cheaper than initially expected, since the defective engine mount was covered under an extended component warranty. The vibration issues completely disappeared after addressing the wiring harness problems. No related problems in the 8 months since the repair. The mount failure symptoms never returned once the electrical connections were properly secured. Regular checks show the rubber mount and transmission mount are holding up well with no unusual wear patterns. A proper diagnosis really made the difference here, what initially seemed like a complete mount system failure turned out to be primarily an electrical issue causing similar symptoms. The idle is now perfectly smooth with no error codes. Make sure to have the mounting points inspected during regular service intervals though. Early detection of any rubber mount deterioration can prevent more extensive transmission mount damage down the line.

I finally took the car to a certified shop last week and got everything sorted. What started as a suspected mount issue ended up being more complex. The technician found both the engine mount and mounting bracket needed replacement due to excessive wear. Total repair cost came to 780 Euro including parts and labor. The shop did a thorough job documenting the failed mount components and showed me how the original rubber mount had completely separated, causing strain on other parts. The repair took about 5 hours since they had to remove several components to access the damaged areas. Driving home felt like a completely different car, no more vibrations, smooth idle, and all error codes cleared. The motor mount replacement made such a difference that I regret not addressing it sooner. Been driving for a week now without any issues, and the engine feels properly secured for the first time in months. Next service I will definitely have them check all mounting points as preventive maintenance. Learned my lesson about ignoring early warning signs of mount failure.
