Pretty familiar with these 35Ds having owned two of them. I had the intank fuel pump replaced under warranty in my 2010, but was not the case for my 2012. I kept receiving alerts in iDrive of a fuel pump issue. Car was still driveable with no issue, and alarm would go away after a few minutes. Got a few codes, namely EKP engine failure for the fuel pump, but also two other codes: 4BDC and 4BDA (both I think are HPFP related)
Per recommendation of BMW SA, advised replacing the intank fuel pump and fuel control module. Because of my work schedule and their lack of openings for service, I had my Indy replace the parts this week. Reprogrammed the car and everything checks out. However, both 4BDA and 4BDC are still present and cannot be cleared. Is this a HPFP issue or something else?
