I suspect my pcv needs replacing due to slight rough idle and misfires. Plugs are brand new NGKs. Coils are also realtively new and the misfires don't follow the coils as I swap them between cylinders.
The question is, do I need to have the ECU flashed after replacing the old part?
I have read that due to part revisions, this may be the case.
Original part number is 06H 103 495AE
Replacement part is 06H 103 495AH
I'm doing the work myself so hoping I don't need to have it reflashed by the dealer.
