2011 N55 335i, I replaced my starter a couple days ago and when I was done it threw 4 codes. The only thing I found wrong with the car is that the charge pipe is super loose on the throttle body, I plan to replace it soon but I feel like just that wouldn’t throw all the codes. Car symptoms are little/no boost, huge loss of power, turbo blow off sounds weird, and bad idle which could all be because of the charge pipe but I’m still concerned, especially since all these codes seem electrical. Could this all be from the charge pipe? I’m still pretty new to beamers this is the most I’ve had to take apart on it yet so any help is appreciated. Thanks! Codes: P0238: Turbo boost sensor A circuit high P00BD: Mass or volume air flow A circuit range/performance - air flow too high P007B: Charge air cooler temp sensor circuit range/performance bank 1 5DF4: wiring supply voltage <9 volts
