hi all newbie here. i have just got a 99 a6 tdi sport quattro saloon auto. love the car but i got it as a trade sale knowing it had probs so it was cheap. just a few probs that id like hepl on if any has any ideas. first it wont seem to rev above 3k just losses all power, not sure if this all the time as ive not driven much. seems ok at light throttle and will go above the speed limit im sure! also when pulling up and at tick over i get oil smoke,not every time but a fair bit then doesnt do it again for some time(turbo seals?) and has anybody suffered from prop/diff vibration at around 80? doesnt feel like wheel balace to me. just a few things to think about! thanks all!
