[Update from BHM......................................................................

Connected the laptop and no faults recorded.

Compared live readings with another GDI and all looked the same.

Tried your ecu on another GDI, and it ran fine so discounted ecu.

Uploaded all the info to the factory who wouldn`t look any further until the earth behind the brake servo was relocated on chassis. Made no difference.

Factory suggested trying the throttle body so changed that, and throttle pedal, but no change.

Tested the airflow meter from another GDI, (even though readings look good) and it now starts like a normal GDI.

Might put it through an MOT tomorrow with the donor airflow meter.


This is me now.......So, no faults recorded. So even with OBD access I would have been screwed at home. It doesn't really explain what's been going on with the MAF. I've cleaned it a couple of times since the first problem, but it never made any difference, so it was never high on my list. I suppose the learning point here is to start with the easy changes.
