Just rolled over 105,000K miles in my 2010 TT Quattro. Just flushed the DSG fluid and changed the filter. Everything felt fine for about 3 weeks, until tonight. pulled out of a side street and got it up to redline but it wouldn't shift into 2nd. Kind of went tap tap on the red line then eventually shifted. I don't think it slammed into gear or anything. After that I slowed down and it sounded like I was dragging over something in low RPM. After getting out, I didn't see anything underneath the car and started moving again, only to hear the dragging clicking grinding noise again. I pull over into a side lot and drive it straight and reverse. While in sitting still in park, nuetral, drive or reverse, no noises. while driving in reverse or forward in first gear, I hear the noise the whole time. Its a rotational click feeling/noise. If I am going like 10 MPH while gasing it, I feel the click/ small grind. As soon as I left off the gas, while still rolling, the noise goes away and doesn't come back until hitting the gas a little bit more.
Check out the video link below of my driving in reverse at low RPM in first gear. Ignore the sound at the beginning of some car driving by.
I am afraid to drive it now and will probably get AAA to take it to Audi tomorrow.
PS: I don't have the skid plate on right now because I just did the flush, so it isn't that. I smelled something funny going on while doing the video as well.
