  • VANOS Failure
    • Description/Symptoms: Loss of power, rough idle, engine stalling, and diagnostic trouble codes (DTCs) related to VANOS (Variable Nockenwellen Steuerung - variable camshaft timing). The seals within the VANOS unit degrade over time, causing improper oil pressure regulation and timing issues.
    • Solution: Replace the VANOS seals with updated Viton seals. Some owners opt to replace the entire VANOS unit.
    • Estimated Cost to Fix: $200 - $800+, depending on DIY vs. professional repair and if only seals are replaced or the entire unit.
    • Recalls: None Found
