I was wondering if anyone could shed light on a problem i've got with my A6. It's a 2005 3.0 TDi Qauttro. This morning I drove through a large puddle ever since i'm getting a slight judder at around 1800rpm. It currently has the infamous injector problem white smoke and poor idle which is being resolved next week compliments of Audi Could this be something related to the injector problem (getting worse) or something completely different such as auto gearbox or egr valve ?? Just preparing to have to part money now if it is something more sinister.
Thanks in advance for any help.
