Common Problems This Part Can Help Address

  • Timing belt slack caused by a worn hydraulic tensioner
  • Belt tracking issues from incorrect pulley alignment
  • Noisy operation from a worn or contaminated bearing
  • Premature timing belt wear related to inconsistent tension
  • Heat- and vibration-related tensioner fatigue in high-mileage engines

Installation Notes and Tips

Verify engine code and existing tensioner style before installation. This part is specified for hydraulic tensioner applications with a roller, so confirm the mounting points and belt path match the original setup on your Audi A4, Audi A4 Quattro, or Volkswagen Passat. Inspect the timing belt, roller, and related wear components during service to maintain correct belt tension and alignment.
