We are loyal VW owners. We are on our 5th VW, a 2005 Golf TDI. After on 10,000 miles we had carbon build up on the fuel injector which was not covered by the 4 year / 50,000 mile warranty. The repair cost about $1,000. VW blamed the problem on WA & OR not having fuel standards. When asked if the vehicle was garaged in any other state would the warranty cover the repair - VW's answer was "no." VW's quality has gone down in the over the years and unfortunately this will be our last VW since the company will not stand behind their product.
The best feature of this vehicle is its 47 MPG fuel economy.
Tell your customers they have to put in a fuel injection cleaner regularly to reduce carbon build up.
