Hello. At the 3.0 TDI 240 hp GP2 Bj 2009 the cylinder head gasket is defective. Water in the cylinders. What do you have to plan for changing costs? Does the engine have to go out? Does 200 Tkm. Should you have other work on the engine in the train? Can someone recommend a capable workshop in the vicinity of Frankfurt am Main? Or just to Rapacho?
