Hello,
I am getting this fault code consistently and its bringing on limp mode
The code does not reappear if it is cleared whilst on throttle and kept accelerating; however on deceleration, when nearly at idle the fault code reappears. When sitting at idle, a little blip (only a couple of hundred rpm) will bring on the fault code as the revs settle again.
I have checked the DV which appears to be functioning properly.
I have a catch can installed so no PCV system and very few under-intake manifold vac pipes to check, although the ones that are there have been checked.
All the hoses around the N75 have been checked.
A different N75 has been tried.
All main boost hoses to/from intercoolers have been checked.
The throttle body gasket has been replaced.
When running with the MAF unplugged the fault code does not appear.
When running with the MAP unplugged the fault code does not appear (although a load of others do!)
The car IS making requested boost, and flowing over 220g/s on a stage 1 map boosting 22psi max.
My suspicion is that the MAF reading it too high and the MAF is goosed!
Does anyone have any other suggestions as to what the cause may be?
Cheers
