Unexpected PAS disconnexion ?

Recommended Posts

Hello

After having disconnected battery for a night to change the Air Filter and the MAF for new; it was impossible to have engine restarted but a quick engine-running during 3/4 seconds and looking as lack of gas.

I suspect having PAS disconnected as if the car would have been stolen;

Impossible to restart correctly

Any idea to recover the situation or have I to go Porsche dealer ?

Thanks for help

If the engine cranks, I don't think your problem will be the PAS immobiliser. If the immobiliser is active it would inhibit the starter motor. I think I would try to check if the fuel pump is running.

thanks Richard I will recheck

but

- at durametric I have an error code on PAS 8004 Supply voltage clamp 50 sc + and 8005 supply voltage clamp) 5 cs+. This is the reason of my suspiscion

- and the engine runned 3/4s not only once but at each starter demand; If the pump failed, I think I could not have these repeated engine starts.

You will probably get those error codes because the battery was disconnected. You should clear the faults and see if they come back. Like I said, if the engine cranks, I don't think it can be the immobiliser.

Right Richard

After erasing faults and recheking all potentail air leaks in MAF, Throttle and IPD mounts, it became perfect

Thanks for the help
