The fuel injection system on my Jetta tdi went bad. The car had 35,000 miles on it which was 5,000 past warrenty. Volkswagen agreed to pay part of the repair, but the cost to me was still over $600. 00. The glow plugs and harness to the glow plugs have also been replaced after warrenty. I have never had so many expensive repairs on a "new" car before. Now the brake switch needs replaced because the brake lights would not come on. Replacement switch has part no. Vwn 1j0945511d.
