Stuck in limp mode help!

[mediaone1]

Car has been running and sounding great then out of no where DriveTrain Malfunction error no hard pulls just started the car then a few minutes later after driving not even a mile the car 428i 2016 went into to LIMP MODE here are the codes:

• 102002 Air Mass too low
• 121533 boost pressure - atomospheric pressure, comparison boost pressure too low
• 120408 charge pressure control, shutdown: pressure build-locked
• 121531 boost pressure, operating range: pressure too low
• 118402 mixture control: mixture too rich, e fl large deviation
• 102A01 air mass meter, signal: electrical fault

I am thinking it can be a bad MAF sensor hopefully or Charge pipe failure. I took a look at the charge pipe from eyes view looks to be intact along with everything else. But I'm stuck in this limp mode not being able to drive past 20 MPH unless going down hill. Car still sounds good, no hard idle, starts fine. What should I be looking for?

You're in the wrong forum - try the F3x forum in the 328/428 N20 engine section.

With pressure too low and air mass too low etc.. sounds like a massive leak going on!
