03E109507P 03E109507B Timing Chain Tensioner for SEAT Leon SKODA Octavia VW Golf

Timing Chain Tensioner for SEAT/Skoda/VW (03E109507P / 03E109507B)

1. Part Numbers: This timing chain tensioner features OEM part numbers 03E109507P and 03E109507B, ensuring precise compatibility with VAG group vehicles. These codes validate its authenticity and guarantee a factory-spec fit for optimal engine timing performance.
2. Vehicle Compatibility: Specifically engineered for:
   • SEAT: Leon (5F), Ibiza (6J), Ateca (5N)
   • Skoda: Octavia (5E), Superb (3V), Kamiq (NW)
   • Volkswagen: Golf (Mk7), Polo (6C), Tiguan (5N)
     Suits 1.4L TSI (EA211), 1.5L TSI (EA211 Evo), and 2.0L TDI (EA288) engines. Verify your engine code (e.g., CCTA, CRHC, DMB) 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 8 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, which is critical for interference engine designs.
