Hello all,

I have a 2015 328i with JB4 and a stage 2+ tune. Upgraded Cold air intake, BOV, ******* DP (no 02 sensors), flow master 10 muffler.

As of late my car has been going into a limp mode after just regular driving. I feel a hard shake, then get a drivetrain malfunction error and the car won’t accelerate. When I turn it off and turn it back on, everything is ok. After looking into it, I’ve replaced the HPFP and LPFP (Bosch) to no avail. It still happens. So I started to log and I’ve noticed the numbers for My LPFP have been in the low 30s. It’ll get up to 70 at times but will drop back into the 30s. I’ve read that it should be between 50-70. I also get a rough idle and hard shifting in between gears. Has anyone else had this problem? Is it common? Would it be in my best interest to upgrade to stage 2 LPFP? Could it be a problem with injectors? Should I scrap the car! Lol. Please someone help me out!

The engine code I’m getting is 1F0525
