Hi there, I have a 2004 2.0tdi a3 and after the turbo started wining I had it on a diagnostic machine. It came up with an overboost condition (obviously the turbo) and the egr valve malfunctioning. I know the overboost could be many things, including the dreaded sticking vains in the turbo itself, but does the fact that I also have an egr issue suggest it could just be blocked causing the turbo to overboost and is simply In need of a good clean?
Cheers in advance for your responses guys, this is my first post and I would really appreciate your views. Luke.
