VW 2.0 TDI timing belt: CRITICAL service. Belt drives water pump, oil pump, injection pump. Failure = bent valves = engine rebuild. Interval: 40,000 miles or 4 years (do NOT trust VW 100k recommendation — oil contamination degrades belt faster). Always replace: belt, tensioner, idler, water pump. Do not reuse old hardware. This is a known weakness of TDI engines. Budget $500-800 for proper service.
