So, I recently purchased a very well cared for 2001 Jetta GLX VR6 with 137,000 miles. The previous and only other owner had been very good about the service, but never had the timing chain replaced.
According to VW you never need to replace the timing chain, but I have read elsewhere that you should replace it and the tensioners after 105k miles. It runs like a dream, smooth and quiet. The mechanic that inspected it said there was no problems. But after reading some of the horror stories of chain failures I'm getting a little nervous. Should I have the chain tensioners replaced on this vehicle or wait until I hear noise?
