Good To Know

Q: Should the tensioner be replaced with every timing belt job? A: Most manufacturers recommend replacing the tensioner damper alongside the belt to avoid repeat labor. A worn damper can cause belt slack or noise even with a fresh belt.

Q: Does this fit every VW or Audi engine? A: No, fitment depends on the engine code and part number stamped on the original unit. Confirm your engine uses 078109479E before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
