I know it sounds strange, but lately while driving in S5 with traction control fully on, as I downshift into 2nd gear and accellerate WOT, I feel as if I'm not going anywhere. It feels like my clutch is slipping and I do not hear any tirespin at all, but the traction control icon is blinking during that whole moment of "slippage". When I arrived home, the car definitely had a faint burnt clutch smell & no burnt rubber smell. Has this ever happend to any of you before?
