Hi,
i have a 2001 Passat 1.8T 20v Sport & have had the P1128 fault code for quite a while. I tried various fixes; every pipe linked to 'bank 1' has been checked / replaced but it doesn't seem to get rid of the fault code.
I've recently discovered it could be a faulty MAF sensor but wanted to check that the symptoms are consistent with this kind of fault.
Initially there were no symptoms when the light first came on but gradually the car has been idling poorly, misfiring, very jumpy whilst the engine is cold & there is a distinct loss of power even when the engine has been going for hours - even on motorways. The car also failed it's MOT due to high emissions.
Could all of this be due to the MAF sensor or are there other things I should be checking?
Any feedback would be much appreciated.
Many thanks
