Hi all, the following code keeps coming back on my mk5 gti.
P2279 - Intake air system leak
Car seems to be driving fine, boosts normal and mpg is ok.
I did the dipstick test and it definitely doesn’t sound right
Does this point to Pcv valve?
Pcv was changed approx 30k miles ago and diverter valve 40k miles ago.
Any further tests I can do to single out the issue or should I take it to the garage for a smoke test?
Thanks
