Thread: D2, V8 non starting event with odd error codes and IACV replacement or repair.

It seems to have a cycle.

Trips into failure. Gets a P01668 code for alarm which seems to set off a can bus fault x 2 that appear under gearbox which is why it flashes the lights (turns out there are 18 documented events that can cause M&S lights. How many more unknown) Clear these and the alarm, then access the BCU (which shuts down the hazard lights and really upsets people when you're stopped first position in a turning lane, they pull up and then the hazards come back on) and disable the alarm and immobiliser. Try starting which will throw another alarm code since it sees the alarm but can't do anything with it. Then re-enble and it may start.

I don't know if it's the messing round and clearing faults or it take long enough to do that, that it cools down enough to make the CKP work again.

Well there's your problem.






I'd hazard to guess that the numpties that fitted the auto under insurance stuffed it. They said that the stack height of the flex plate and spacers was out, and when checked with Ashcroft there is a difference between the pump height on the 4HP24 V 22 so I had one of the spacers surface ground. I thought that they'd been conscientious and measured stuff but clearly they fitted it and it made a noise and decided it needed fixing. How it's worked and run to date (almost 2 years) is beyond me but it is a bosch part. If it was lucas...
