6 speed on the A8 4.2 TDI. I gave the car some abuse today on the way home. Nothing major, just a spirited drive home. Few roundabouts so some kickdowns and full throttle shifts. Had the car in S on the box. Got home and jesus did it stink like clutch. Should i be worried?? Box is always silky smooth and you cant ever feel it change up / down unless its cold.
