Left head light burned out and blew a fuse. This caused the left tail light to burn out. The problem was a wire that became exposed and grounded out. The wiring harness is attached to the head light fixture. In order to properly correct this problem, the head light fixture should be replaced. This cost is about $350... to change a head light bulb!!! Bad engineering and weak product quality. This problem occured at about 120,000 miles. The more I research these VW's, the more I find that at about 100,000 miles these cars should be dumped. Do not depend on their reliability after 100,000. My Gulf TDI was purchsed new, all maintenance was performed timely and all repair parts and labor were competed by certified VW mechanics.
I had to replace the harness for the light bulb. Bulb still worked but harness would only work if pressure was applied.
wiring was crumbled near harness. during installation of new bulbs circuit shorted out. having to replace harness - substantial expense.
Right head light burned out on low beam the second time.
When replacing the bulb most of the insulation on the wireing crumbled and fell off.
Exposing much of the wires inside the houseing.
I change the light bulbs 2 or 3 times more often then on any other I own or owed before.
