New Owner M4 problems..?¿

[ALCOBENDAS]

Hello from Spain, I already bought my M4 in Germany, it has come with some bugs that after deleting them are still present to see if you can help me. It has no license plates so I have not used it yet just start it in the garage. Bring this accessory connected to the obd2 .. Thank you

What modifications came with the car?
The 180101 is a low-side O2 sensor error possibly from hi-flow or catless DPs. Maybe someone did a quickie DP install and twisted/ruined a wire?

Do you have an aftermarket exhaust and the valve plugs are disconnected? I see a can flap module box in your pix.

The car, it is supposed to be all stock ... I know it was originally fitted with an M-performance exhaust ... I don't know if they ever installed a downpipe ... but right now it is not installed

The module box you know how it works .. is it automatic when connecting to obd or is it configured with some oem buttons in the car?

Thanks

The box seems to be an aftermarket controller to open/close the valves at will

If you're having error codes then ignore the add-on flap controller for now. Get the OEM flap actuators plugged back in.

If you still have the 180101 error then check your O2 sensor next on your OEM cat downpipes. Maybe twisted/broken/shorted sensor wires causing other faults.
