Sure Track Real Fix: PCV Valve Victory!
The customer reported that the check engine light was on in their 2020 Skoda Kodiaq 1.5l petrol. A scan tool revealed a fault code indicating an intake air system leak. Using a smoke machine to test the intake system, no smoke was detected from the positive crankcase ventilation (PCV) valve. However, further tests showed that the PCV valve was leaking as it failed to retain vacuum. To resolve the issue, the PCV valve was replaced, and after clearing the codes and conducting a road test, the vehicle operated properly with no illuminated check engine light or fault codes.
