Hi, hope someone can point me in the right direction. I have an '02 C5 and about a week ago I felt the car wasn't running right, I could feel vibrations coming up through the clutch when maneuvring in 1st or 2nd gear and a slight drop in power, so I thought maybe I needed a fuel filter. I was out last night and again this morning in it, and when I was trying to get up to speed when I dropped the foot the engine revved out fine and as soon as I heard the turbo kicking in I had total power loss, it was like the clutch was depressed halfway or something. I can gradually, slowly, build up speed ok, it's only if I drop the boot, move up through the revs and hit the turbo quickly (not horsing it but not old lady style either) away that I lose power. Anyone got any ideas? I just want to get a figure in my head before I go to the mechanics as I don't want to get my pants pulled down. Only spent 500 quid on it about 3 months ago.
