Hey guys relatively new to cars and bimmers in general and had some questions about some codes. Lately my car has been shutting off randomly not super often but every once in a while. At times the power will feel normal but other times i have to push the throttle all the way down to get to 4k rpms. The service engine light and half check engine light come and go usually after i turn off the car for a bit. Thought it was a vaccum line issue so i replaced one and I dont hear air leaking anymore but still has some of the same problems.

Codes:
- DME active codes -
2774 - Air volume, plausibility: Air volume too high.
2BC1 - Mixture control: Fuel-air mixture too rich.
2C01 - High pressure fuel, plausibility Pressure too low.
375C - DME, protection against tampering: Program or data manipulation detected.
387F - Power management: Standby current violation.

- DME shadow (inactive) codes -
2BDE Fuel high pressure on enabling of injection: pressure too low

Mods installed:
Catless dp
stage 1 tune
bms intake
vrsf chargepipe

Car-2011 335i n55

Any help helps!

I think the HPFP is on the way out. I had codes 2C01 and 2BDE on my N55, which were resolved after replacing that part. I also replaced the high pressure fuel sensor.
