I having been having the "charge pressure control - negative deviation, intermittent" fault for so long now.
Symptoms: Poor, rough acceleration. Can bearly accelerate to 3000 rpms without going to limp mode.
Attempted Cure: Changed 3 MAFs, 2 MAPs, 2 N75, complete pipework from turbo to IM including a new intercooler, stripped out and cleaned turbo. Cleaned out IM.
I did get some improvement following the pipework change but nothing compared to how it used to be. I used to have a lot of Black smoke before the pipe change. That is gone now, so I know there is no leak. I even had compressed air pumped into the pipework to look for leaks so I am sure I dont have air leaks.
Can any one point me in the right direction before I go mad. I miss my old baby
