Hi all, I bought a 2006 2.0 tdi 140bhp s-line and when it's just idling say when I stop at traffic lights or when I start the car it kinda wobbles but when I'm driving its perfect and full of power. I cleaned the egr valve and cleaned the throttle body and they were bad dirty and are spotless now and I took the fan belt off to see if it was the air con compressor but no. I don't think it's an injector because it is so easy on diesel. I'm stumped? Any help would be great!
