Have a problem with my Golf GTD 2.0 135 KW Bj. 2016 Auto has run 65,000 KM and plays with the cooling all at once crazy, water loss! Diagnosis with VW head seal defect, estimate including new additional coolant pump (water pump?) 4500 € !!!!!!!!!! I thought hit me Then it is not yet excluded that the head got what and needs to be revised which drives the price even higher !! Research on the Internet for repair, so in this case for the first time only the gasket change resulted in completely different prices! Another VW specialist company demands for the gasket change 2.200 € A free specialized company 1.200 € !! How can it come to such price differences I ask myself, rip off ? But now comes actually the most important question: Can a same engine 2.0 GTD 135 KW from an accident car Golf 7 GTD , only oil tank damaged , mileage 37,000 KM with warranty for 1800 € get only the engine is year of construction 2018, which is not close So is one of the last from the series of seven Then came the model 8 question to a connoisseur, is the engine of 2016 identical to that of 2018 as a compatible ? Thanks for professional answer Bernd
