Hi could someone please help me out please.
Couple of weeks ago the coil light on my van started to flash and went into limp mode, stopped for 10 mins and re-started all seemed fine until a week later and the same fault appeared again this time with the engine management as well as the coil light.
Seems to be in limp mode all the time now no boost at all, the large pipe coming from the inter cooler to the throttle body doesn't swell during revs i can depressed the pipe with little force and it remains depressed all the time.
I've change the G31 Sensor and N75 boost pressure valve no improvement.

Thank you kev

Piper1, noted you changed the sensors but would need a wire diag to validate circuits. One noted implausible and the other open.

Would be looking at ground and reference voltage on those sensors. May be new but is there a transfer of information?

Hi Larry thank you for the reply.
Where would i be able to obtain a wire diag for my vehicle, is this a repair that would need to be carried out be a auto electrician.
Cheers kev
