Re: Motor Control System Failure (oh no not again!!)
Chris, I have exactly the same prob at startup, I have had the codes read 2 or 3 times, clearing them each time, and 6 codes will appear every time, ranging from maf, to overboost, to heater plate (glowplugs?) 1 unknown, even once had cruise failure - yes the ecu may support it, but there is no wiring in place for this year car.
I have tried various maf's, no joy, the boost (map) sensor is a couple of thousand miles old, (that said, the problems started since changing that)
the overboost / vnt module I shall repalce as preventative maintenance - just in case - as its 170k old - failing that, I may go back to the old map sensor to see if it makes any odds.
I have even put back in the standard 140bhp map to see if the tuning was at fault, but it still happens with the snail pace map in the ecu!
