Error Codes P01C8, P0174, P0171
Good ole Drivetrain malfunction, pulled the codes P01C8, P0174, and P0171. Engine bank 1 and 2 too lean, fuel pressure low.
Just crossed 40k miles, thinking it could be the HPFP? Run Techron every 3k miles, since i just crossed 40k miles about to change coils and plugs.

Classic BMW replaced bank 2 HPFP with associated seals/gaskets. Car runs great, semi annoyed they just didn't replace bank 1 HPFP while they were there but still have 2.5 years of warranty coverage left.
