Timing Chain Tensioner Repair Kit — VAG 1.8 / 2.4 / 2.7 / 2.8 / 4.2L | OEM 058109217B / 078109087C
Restore Correct Timing Chain Tension on Your Audi or VW — Rebuild the Tensioner.
A worn or leaking timing chain tensioner on VAG 1.8, 2.4, 2.7, 2.8, and 4.2L engines allows timing chain slack — causing rattling on cold start, timing drift, and potential engine damage. This repair kit rebuilds the tensioner with new seals and internal components, restoring correct chain tension.
Why Rebuild the Tensioner
- Eliminates Cold-Start Rattle: Correct tensioner oil pressure eliminates timing chain slack on cold start.
- Prevents Timing Drift: Proper chain tension maintains accurate camshaft timing.
- Major Savings: New VAG timing chain tensioners cost $80–$200. This rebuild kit costs $14.
