Understanding what’s included in changing timing belts of any car can help one better understand what should be included in this service.

Pat Goss reviewed timing belts on in a current episode of Motorweek, and although the reference is not TDI specific, the . Due to improving the timing belts, the life of a belt is much longer, but what other replacement parts need to be considered?

For many small diesel owners, the timing belt change can be the single most costly service they encounter, and it can quickly increase the cost of ownership.

If you are an ambitious weekend mechanic and have access to special VW oriented tools, the extensive repair can be done at home. You might want to observe someone else doing a timing belt change first, either in person or on video since the service is relatively extensive.
