I tested the car again, runing good now and no more leaks just the VVT gasket. But i don't have VCDS at the moment to check the fuel trims.Yes, the 1.8T is susceptible for boost leaks with the elaborate PCV system
I will clear codes and check for misfires and also the fuel trims, will post the results here.
Questions:
Because i can't find the PCV hose, can i do it with 2 hose connectors and silicone hose?
Can the VVT gasket be changed without taking apart the camshafts?
