Sudden Fault codes; Engine, Gearbox and ABS

[SilverS8]

Good evening.

Was just out for a quick drive and on a on-ramp i decided since its Friday, i'll let the S get some exersize.. Flat out on 1st in manuel, hit the rev limiter and auto shifted to 2nd and then when revving just past 6000 rpm there was a clear brief misfire but it kept pulling to the end.
Eased off and there we had ABS and Traction control (the A with a ring around it) light permanent on.
Car runs perfect, no hesitation or anything, idles smoothly.

Connected Vag-Com and got these 3 fault codes

Neither of the 3 codes above is possible to delete, shows right back up when deleted directly in the module.

I tried ENGINE-Measuring Block 32 : all 4 fields display 0 and do not change while driving.
I tried ENGINE Measuring Block 2: The G/S is a steady 0,56 at idle. I took it for a spin while logging and from what i can read out off the excel sheet it never reaches above 0,72 even at WOT and going all the way to the redline.

I have seen several threads in here with somewhat the same problems, but most of them also have problems with fuel banks/lambdas etc etc.


All suggestions appreciated.

Cheers.
