No test on MAF
No test on MAF its not in limp mode . its drives good but just not that 1.8t boost it shoul have. dv replace . n75 working I bypassed N249 which many people do to see if its that valve
so your saying that it does not have a check engine light on ?
check to make sure that the hoses to the turbo condenser are tight and not leaking
check the turbo wastegate, it will not throw a code
what engine in the car
1.8t no leaks
then you must test the turbo wastegate. remove the hose from the wastegate and blow shop air into ot and see if it works.
