Hey, I just bought a 2013 335i e92 n55 from Copart recently and I just ran the DME codes on it and i got these ones, please let me know if I should be concerned or just delete them, also lmk if there's anything I need to fix

- DME active codes

2774 - Air volume, plausibility: Air volume too high.
2BCO - Mixture control: Fuel-air mixture too lean.
2BEB - Mixture control: Fuel-air mixture too rich,
large deviation.
387C - Power management: Battery, total discharge.
3887 - Vehicle voltage, working area: Voltage too low.
38AC - Intelligent battery sensor (IBS): Wake-up line,
short circuit to ground.

- DME shadow (inactive) codes

2904 - Charge-air temperature sensor: Multiple fault.
2908 - Charge-air temperature sensor: Multiple fault.
29E - Charge-air temperature sensor, electrical:
Short circuit to B+.
2¢42 - Mixture control: Multiple fault.
2CF5 - Oxygen sensor after catalytic converter: Signal
fixed at rich.
2D45 - Valvetronic, adjustment range: Stop not
taught in due to ambient conditions.
321C- Fuel tank ventilation system and purge air
system, minor leak: Leakage greater than 1.0 mm.
378F - BSD, message; electric coolant pump: Missing.

Erase and see what comes back. Might have a bad/dying battery or alt, or damaged wiring/part for IBS/BSD wiring, from the looks of some of the codes, but depends what comes back.

These are the ones that came up after I cleared it, anything I need to replace or be worried?

- DME active codes

None

- DME shadow (inactive) codes

2904-Charge-air temperature sensor: Multiple fault.
2908 - Charge-air temperature sensor: Multiple fault.
29E0 - Charge-air temperature sensor, electrical:
Short circuit to Bt.
2CF5 - Oxygen sensor after catalytic converter: Signal
fixed at rich.
321C - Fuel tank ventilation system and purge air
system, minor leak: Leakage greater than 1.0 mm.
378F - BSD, message; electric coolant pump: Missing.

I'd just start googling the codes and see what most people had issues with when they had those, and also check the wiring for those sensors to make sure damage isn't causing the codes. Looks like possibly need new o2 sensor and tmap sensor, but you'll want to do some troubleshooting to be certain.
