I'd recommend unplugging the module for 10 minutes and see if that helps.

If you look into the 'hole' where the module is, towards the front of the car is the 'system' cable for the module. You will see a white lever on the multi-plug. You need to press in the locking catch on the back of the plug and then swing the lever inwards towards you - this will disconnect the multi-plug.

Leave it out for 10 mins then re-insert, locking it in by swinging the white locking lever the opposite way until the plug seats.

May fix it - may not. You may also want to delete the pairing from the BMW module - set up pairing on the car by pressing the pairing button until it says 'Pairing', then press and hold the pairing button for >10 seconds until you hear three beeps. Should say Pairing Deleted or something similar.

If you have Assist though, it's a different module and I don't know if the connector is the same.

HTH.
