2021 VW Tiguan R-Line United 🇩🇪
Came in with a major engine oil leak after the customer heard a loud pop while driving. Inspection revealed a cracked oil pan and multiple oil leaks.
After diagnosis, excessive crankcase pressure from a failed PCV valve was found to be the root cause, contributing to the cracked oil pan and upper timing cover leak.
Re-sealed the affected areas, replaced the failed PCV system, and upgraded to a reinforced aluminum oil pan to help prevent future failures.
✅ Leak repaired
✅ Root cause addressed
✅ Upgraded oil pan
