So my car has the engine check light on, and threw 2 codes and I could not find what it means: P3090, P142E. Anyone experienced or have a clue what those codes are? Any help will be appreciated, Thanks.

From 1addicts:

"Fault codes
Hi there

Can anyone advise me what may cause the following codes on my 135i:

29F2 Fuel high-pressure system, fuel pressure
Lower rail-pressure threshold value undershot
SAE diagnostic trouble code: P3090
Rail pressure 4075.553 mbar

29DC Cylinder injection cutout
Pressure too low in high-pressure system
SAE diagnostic trouble code P142E
Last at engine temperature 72 C

She is idling rough, doesn't boost at all, struggles to rev past 1500rpm. Only 2,100km on the clock and less than 2 months old."

From the responses, it sounds like a failing hpfp.

I got the same 2 codes when my HPFP began failing. Take it straight in for a diagnosis/replacement, its only a matter of time before it stalls in the middle of traffic and/or won't start and/or goes into limp mode.

Thank you for everyones response, yeah going to take it in on Friday. BMW needs to do something about this fuel pump issue, like have one that works right!

Did it end up being the hpfp?
