I am fresh in the forum and I am looking for a qualified workshop in the Ruhr area for my 4D2 3.3 TDI BJ 2001.
Unfortunately, the great friendly in Essen has not really convinced me so far, and on the left Lower Rhine it has had its difficulties.

Are there any experiences / recommendations on your part, who is still familiar with this model? At the moment, cooling water losses (two or three hoses in the engine compartment have already been changed), I have now had a fresh water running over my shoes in the interior on the driver's side and the heating is no longer ... VAGCOM does not output any error code for this.

I hope to draw from your great experience and I am grateful for every answer,
Best regards, Hans-Peter
