057109510A 95510551000 Engine Timing Chain Tensioner for Audi Q7

Engine Timing Chain Tensioner for Audi Q7 (057109510A / 95510551000)

1. Part Numbers: This timing chain tensioner features OEM part numbers 057109510A and 95510551000, ensuring precise compatibility with Audi Q7 models. These codes validate its authenticity and guarantee a factory-spec fit for optimal engine timing performance.
2. Vehicle Compatibility: Specifically engineered for:
   • Audi Q7 (4L): 2006–2015
     Suits 3.0L TDI (CRCA, CASA), 4.2L FSI (BFM), and 4.2L TDI (CASA) engines. Verify your vehicle’s engine code (e.g., CRCA for 3.0L TDI) and production year for exact fitment.
3. Function and Quality: The timing chain tensioner maintains optimal tension on the timing chain to prevent slack, noise, or misalignment, which can cause engine damage. Constructed with a high-strength aluminum body, hardened steel piston, and integrated hydraulic damper, it withstands high engine pressures (up to 10 bar) and temperatures (up to 130°C). The design includes a self-locking ratchet mechanism and wear-resistant plastic guide to minimize chain wear. Replace during timing chain service to ensure factory-spec performance and prevent premature tensioner failure, critical for interference engine designs. Direct replacement for worn components to restore engine reliability.
