iTrader: ( 0) You shouldnt be crashing HPFP on pump gas with only 17-18 psi of boost. The fact that the car stalled afterwards as well is another clue it was more than just the HPFP not being able to keep up with your boost level / fuel demand. You either have a LPFP issue (most likely) or a HPFP issue (less likely since its mechanical).Very typical. The PVC vales are integrated into the VC and if they go bad they cause excess crankcase vacuum. This in turn draws air in past your main seals and makes a squealing sound. To test for a bad VC, remove the engine cover, remove the hard plastic cap over the vac nipple (right next to the electrical hazard sticker), using a tissue see Nickory Discussion starter. 2 posts · Joined 2013. #1 · Jan 2, 2013. I bought my BMW 2013 328i YESTERDAY (New Years Day) with 10 miles on it. I drove it 34 miles to work this morning. I drove it (almost) home ~33 miles this evening. On the way home, while in Eco mode, I started getting yellow "Drivetrain Malfunction: Drive Moderately" alerts.
Adaptive M suspension problem. Hello, I have BMW 4 F36 with adaptive M suspension. Last week I was at my dealership performing regular oil change in my car and they also updated software with the new version. After this update my car is firmer and actually there is basically only slight difference between Comfort and Sport suspension settings.
