       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 chassis type for exact fitment.
3. Function and Quality: The timing chain guide maintains proper alignment of the timing chain, reducing wear and preventing slack that can cause engine misfires or damage. Constructed from high-strength composite material with glass fiber reinforcement, it withstands high temperatures (up to 130°C) and dynamic chain tension (up to 800N). The guide features a self-lubricating nylon surface and integrated metal inserts for durability, while its precision-molded design ensures seamless OEM integration. Replace worn guides during timing chain service to address common wear issues (e.g., plastic degradation, rail deformation) and restore factory-level timing precision.
