had my audi about 1 and half years now and its starting to get to me, since my warrenty ran out i have had nothing but problems with it, it started lagging and went into limp mode and found out that my oil tandum pump had failed, which i got replace and drain whole fuel system, but still im getting problems.
When starting it up it is very lumpy from cold but if started up once warm is nice and smooth. also while on idle it doesnt seem to idle at once place instead it pulses slightly, which also seem to be when its cold. my car is a 170 2.0 tdi a4 b7.
if anyone could help me to try correct these problem would be fantastic or have experience them same issue and managed to sort them would help loads thankyou
