N55 Sudden Codes P1290 P0100 P15DF

Hey Forum,

2014 F30 335i 6MT MPPK and Dinantronics, 93k miles

Had this car for about 2 years and haven't had any problems.

Pulled into a gas station last week and when I came back and started the car it was running very rough, then shut off completely. Error codes, limp mode, etc.

Shutoff and restarted multiple times. Car cranked for a while and wouldn't start. Let it sit for a few minutes, started again. No problems, but CEL on.

I got the car home and ran the codes from OBD.

P1290 P0100 P15DF are permanent codes.

P0300 pending. All cylinders besides 3 have misfire codes pending. Also have P12B9 pending.

I searched around on the forum a bit and I'm thinking that it could be the HPFP. However I found some info that suggested it could be related to the Dinantronics tuner or the MAF.

I think I'll start by replacing the HPFP but any suggestions would be greatly appreciated.

Thanks!

If you are still having this issue you may want to return the car to stock tune and scan the codes again. I have an F36 N55 and was getting a few valvetronic codes that appeared out of no where. The car just started running very rough with no power. I was tuned with BM3 stage 1 when I read the codes. It was suggested to flash back to stock and then rescan the codes. I flashed back to stock and found a misfire in cylinder 6. Swapped the coil pack to cylinder 1 and the code followed. I replaced the coil pack with a delphi coil (which is what I have installed) and the issue was resolved. Coil pack was $30 on amazon and shipped in 2 days.
