My mate had one just last week!
He took his VW Golf GTI into a VW dealer to investigate a strange knocking noise from the engine bay.
VW told him it was coming from under the engine - maybe something loose etc, so they would have to remove the entire engine to investigate and repair. He was told that it would be at least a full day's work, and he was looking at approx £1500 for the entire job!
Yes - £1500!!! This is a VW main dealer!
My mate took the car away. He had a guy at his work look at it.
You wont believe this...........
It turned out it was the ENGINE COVER slightly loose, and rattling!! As soon as you held the engine cover down a little from one side, and gave it some rev's etc, the car made no rattling noise any more!!
He took the car back to the same VW dealer. They replaced the engine cover free of charge in the end!
He's going to write in to complain about this - as he's had numerous bad times with this dealer (he bought the car from them brand new originally as well).
He stated on their survey that he would not recommend them to others, and the dealer had the nerve to ring him back a few days later asking if he wuld ammend his survey to say he would recommend them, as it looks bad on the dealership otherwise!!!!!
I must admit - VW make great cars, but their aftercare service is absolute pants!
