Hi Matt,

I should have something, I'm away for a couple of days but give me a shout if you still need it later in the week. I'm back at work Thursday.

Thanks Mark. Not having live data for the ABS on this car it's back to the good old fashion ways

I'm down your way next week and could bring a PST with me if it would help?

PST?

The car is not in the workshop at the moment and he doesn't live very close. I'm trying to gather information at the moment to make diagnosis easier and stop him having a 100mile round trip.

I have a feeling that its got something to do with the MAF fault that is being triggered with the ECU. Apparently they are prone for ABS/PSM faults with this PCM fault code. I have seen live data from the PCM and the MAF looks a little low to me but not a million miles away. The MAF has been replace by someone else with a genuine part and its was date code on it for the end of last year. I have smoked the inlet system and that all looked good but on full boost this will hit 0.8bar and my smoke machine is never going to be able to recreate that.

Porsche System Tester.

They made a PST then a PST2 and after that they called the Tool a PIWIS

I see I don't know much about Porsche diagnostic stuff pre PWIS. Just a wiring diagram for now should do it. I can get fault codes just no live data.
