Check your fuel pressure.
I have fuel pumps if you need. They are under rear seat. |

Dealership changed my fuel pump last year and error gone. No issues since then. Dont waste your time on sensors / regulators, etc. It is the fuel pump. |
Thanks for the info im going to take it to the dealer next week, can i still drive the car there?

Yes you can, fuel pump goes into "safe mode" and pumps constant higher fuel pressure. I drove and raced my car for over a year before getting the pump changed. Worst case is your car runs too rich.
I have a 2009 E63 with a fault code P2540 that comes and goes , the car has 2 fuel pumps under the seat, how do I know which one needs to be changed, or which one to order online , websites says primary fuel pump and secondary fuel pump. also does this affects the 0 to 60 performance, because the best that could get was 5.2 sec Thanks a lot for your help. |
