I have trawled though the forum, and found so many variants of this issue, so I thought it best to describe mine.
I have a 2004 A4 1.8T Avant CVT ltd ed. I have an annoying light car judder/shake when I am cruising or lightly accelerating around 1500-2500rpm (approx 50-70mph). it happens up and down the range. it doesn't happen if i accelerate/brake heavily.
My clutch has been overhauled and uprated to 7 plate c/w ecu replacement in August 2012 by a local auto specialist. Around the same time I had the cam belt/long life service. Recently changed the MAF, replaced the oil breather pipes and n.r.valve (clogged pipes), rocker cover gasket and new platinum sparks. I have stupidly replaced the coil packs with second hand ones, but still no change. My handheld does not show any fault codes (admittedly, not a VAGCom)
I am not expecting a exact answer, but some guidance to possible solutions.
I'm really losing confidence in the car....and ran out of funds!
Any suggestions would be highly appreciated!
