Fault Code 120308 BOOST PRESSURE CONTROL, PLAUSIBILITY: PRESSURE TOO LOF

[Jeyz_640GC]

Hi my 2015 640I Xdrive is been Mis-firing when I accelerate. I took it to my local BMW dealer and they showed the fault Code 120308. BOOST PRESSURE CONTROL, PLAUSIBILITY: PRESSURE TOO LOW. Has anyone experienced this problem? I have an appointment with BMW next week. Just Wondering what to expect. Also, The fault code occurred about 1200 miles ago...i Took a country trip and felt was driving rough...but I thought it just needed a tuneup! 😳

You can google the code and read about it. You may have a cracked or loose charge pipe.
