Hello. I bought this car it had 27,000 miles, now I'm at 75,000. Just had it in for an oil change and was told that it is leaking oil in the back of the engine and that this is a common problem with this motor. This is from the VW dealer. I have done all regular maintenance since I have owned the car and I'm now concerned about the reliability of this car. The dealer is stating that this costs around $4000 to fix. Has anyone else experience this issue?
