X5M e70 engine malfunction reduce power

[x5mkal]

Hi guys

I was running low on fuel and had the engine malfunction come on, had it checked by my friends snap on diagnostic and it through loads of fault codes, help needed as don't no where to start I've been told
It's hpfp

Thanks

Could be a single injector, plug or coil pack would be my guess as it doesn't say multi-cylinder issues.  Worth checking the fuel filter too in case it needs replacement and is crudded up?

Thanks for the reply

Have you tired clearing the codes and seeing if they come back in the first instance?

[x5mkal]

Yes cleared all codes, but 2B2A still showing also I've just noticed my engine fan is running countisouly on start up, checked the AC and its switched off

Thanks
Kal

your code reader says 2b2a is fuel pressure related?
Shouldnt that be Idling speed control valve initialisation?
I think your issue may be linked to throttle actuators?

Got it booked with the dealers, time for a big bill

I had some minor parking damage repaired to my F10 M5 and whilst it didn't have much fuel in when I dropped it off it had bugger all in when I picked it up  >:D

I ran out of fuel ¾'s mike from the Coachworks which didn't go down very well!

Cut a long story short the car took half an hour to get going again and threw up exactly the same faults as you have however once it had a good flow of fuel it was all back to normal. I think at one point I was deep in the brown smelly stuff but it seemed to sort itself out.

Has the car run since you filled it up?

Hi

Yes the car starts and drive but has no power, think the fuel pump or hpfp needs doing

All fixed guys by myself, hpfp bank 1 replaced running like new again
