This is my second Jetta TDI. The first was a 2001 and am now driving - working on my 2006 Jetta TDI. I have experienced a power window cable failure on the 2001 and replacement of the engine temperature sender on the 2001. Now I am replacing the cam, lifter caps, cam bearings and seal, the timing belt, water pump, and pulleys on a 2006. I have found that the 2006 is fairly easy to work on and pretty basic as far as these issues are concerned. I found Aaron at Boraparts.com an online parts supplier is excellent to work with and I feel the prices are reasonable. There service is exceptional and would recommend them to a friend.
