I have a P08 2 days ago....
Same trouble like yours..

The symptom...
Solid cel , no code
Fuel pump sometimes no prime
Fuel pump sometime prime non stop.

Caps all changed
Ic17 changed
Qm3 measured as good

I suspect trouble from Hic1 because previously owner claim the ecu has Cel9 error code.

Anyone with experience and solution?

Thanks... Hope to cure this.....
