Couldnt get rid of the fault.
Replaced fuel breather valve, since its a cheap part to try, but it didnt help.
Finally i went back to the dude that fixed my stage 2 software, we removed the software, updated/downgraded whatever u wanna call it, the ECU/DME.
The problem now seems to be gone.

Which software?
