Everything looks OK. Scaned the trouble codes:
4732 - Fuel Pump
P3045 00 [101] - Electronics Defective
4735 - Fuel Pump
P3044 00 [100] - Short Circuit
2838 - Fuel Rail/System Pressure
P0087 00 [100] - Too Low
Only thing left is fuel pump control module. I think I will order one and see.
Anyone has any other ideas?




Yeah that's interesting for sure. I would check that plug and the cables that connect to the HPFP. I would also check the injectors. But yeah it's a pickle for sure.

Bonne Chance mon amie. Let me know what happens, I'm really curious.

I replaced fuel pump control module 2 days ago and since then car is going OK.
