Hello everyone,
It seems highly unusual for the high pressure fuel pump to go bad on these N20's, yet somehow I think I've done it.
The car is a 2013 328i w/ xDrive, 86k miles on it. Driven pretty lightly, lots of freeway miles and 85% in Eco Pro. I did put on a BM3 stage 1 tune in September.
I had some oil dripping onto my downpipe and smoking up the cabin. General recommendation was to replace the valve cover, as they get old and tend to crack. Upon putting everything back in place, the car is not running well and throwing a low-pressure code: 11A002 - high-pressure fuel, plausibility: pressure too low (& 11AC02 - cold start version).
It bogs down before climbing when pushing the pedal quickly. It also won't idle below 1k rpm with the engine code. Clearing works for a few seconds until they come back up.
I monitored with the BM3 diagnostics and saw the LPFP is holding constant at 84 psi. HPFP ranged between 115-150 psi, target was between 1100-2800 psi.
I've taken the pump off and inspected it. Nothing
seems broken. Is there a way to test these? Feeling very stumped at this point. Thanks in advance.
