2002 Jetta tdi wagon; I have had 6 glow plugs replaced then told that the check engine light was for a bad glow plug harness. Dealer in buffalo told me that the oem harness was made from inferior materials and many fail, but no recall has been issued; now faced with $150 parts and labor to replace this defective harness.

I have a 2002 Jetta gls tdi. I am constantly replacing glow plugs. Have a coolant temp code reading for quite some time and also fuel injection pump, which is probably what is causing glow plugs to go bad.

I own a 2002 VW Jetta tdi (diesel). At 49,500 miles, the engine stopped running. The problem was a clogged fuel intake system. The car is still under warranty. I was told that the warranty does not cover this problem, as it is a maintenance issue. I called the VW headquarters, and they explained that this problem should not occur if scheduled maintenance was performed. I have done all of the scheduled maintenance, at a great expense. Finally, VW has agreed to pay half of the $520 bill to clean the fuel intake. After doing web research, this seems to be a problem facing many VW tdi owners. Because VW told me this problem should not occur with routine maintenance, I believe that VW is not honoring the warranty by paying the entire expense.
