Audi VW Timing Chain Tensioner - Genuine VW Audi 077109087P

Product Information

An Engine Timing Chain Tensioner preloads the timing chain to prevent slack in the timing chain system. Too much chain slack will result in derailment of the timing chain which could cause engine failure. Engine timing chain tensioners are typically oil fed so it is vital to verify you have adequate oil volume and pressure when troubleshooting the timing chain tensioner. Common failure systems include chain rattle or slap on startup, or camshaft/crankshaft correlation fault codes.

• Rattling or Clanking Noise: One of the most common symptoms of a failing timing chain tensioner is a noticeable rattling, clanking, or ticking noise, especially on startup. This is because the tensioner may no longer be maintaining proper tension on the chain, causing it to become loose and hit surrounding components.
• Check Engine Light: A failing tensioner can cause timing issues that may trigger the vehicle’s check engine light. Common faults codes will correlate to a camshaft/ crankshaft fault as these sensors will detect that the timing is off.
• Valvetrain or piston damage: As the timing being off significantly enough in an interference engine can cause the valvetrain to come into contact with the piston surface
