No start, Multiple Errors, No OBD conn.
Hello friends,
Looking for some help here as my frustration grows. This is a 2016 328i GT N26. The car has been sitting for about 14 months now due to throwing a rod. I have started it and moved it several times throughout the year, but the other day after I moved it, I went back about 2 hours later to move it back, and it wouldn’t start. No crank, no solenoid click, no relay click, nothing. At the same time the drive errors included Spolier malfunction, drivetrain malfunction (which I’ve had since the rod problem,) brake system malfunction, fuel system malfunction, and to top it all off, I can’t get my OBD tool to connect. Also, it sounds like the fuel pump runs continuously when the car is on ACC. The OBD port has power, and I can connect to the reader, but the reader does not connect to the ecu using even the most basic types. I have been charging the battery for about 24 hours now because I couldn’t even keep the dash displays to stay lit up when clicking the ignition button other than the fuel pump starts running. Without access to my scan tool via OBD2, I am not sure whether I start. |

The car has been sitting for some time, and although I keep charging the battery, every morning it’s at 11.1 volts, so I’m going to start with that. Gonna order one tomorrow.
I checked the DME connections and they all seem good. |

So, replaced the battery, double checked to make sure it was good. Still having the same issue.
No connectivity to the OBD port Drivetrain malfunction Spoiler malfunction Brake system malfunction Fuel system malfunction Gauge cluster goes on and off randomly The P on the shifter flickers Fuel pump runs non stop Everything else as far as accessories work as expected. Checked all the connections I could find. Not sure what’s next? Fuses? |

The braided ground that goes from the engine to the chassis is falling apart and rusted. I jumped the block straight to the battery and all the issues went away. Thanks for the help! |
