Hey guys. I have a 2012 550i with full exhaust (vacuum lines are plugged) and JB4 Beta. When doing high speed pulls, I get a Drivetrain malfunction code: “Charge pressure control: Plausibility, pressure too low” on both banks. This code does not throw the car into limp mode and often goes away without me even restarting the car. I’ve heard multiple reasons if could be happening and want to see if anyone has any idea.
Things I’ve heard:

Plugged exhaust vacuum lines are leaking.
Charge Pressure sensors need to be changed
MAF’s need to be changed
Wastegate Actuators need to be changed
Kinked wastegate Hoses need to be unkinked

Does anyone have any form of information on how I can tackle this issue? Thank you so much.

Have you tried putting the vacuum lines back on the exhaust baffle? I doubt they are the cause though

I haven’t because I removed the tips for aftermarket ones :/. I have them plugged with a screw and secured with a zip tie
