I'm getting ready to take on the task of changing timeing belt on 2004 jetta tdi. Any advice would be greatly appreciated. I have 204,000 miles on jetta. I had dealer change timeing belt 1st 100,000. If I inspect belt and it looks good with no cracks and signs of wear should I still replace? The dealer said when they replaced it at 100,000 it looked brand new. I put alot of highway milage the vehicle.
