Qubo Proxi alignment failed

This is a 'asking for a friend' post, so more detail will require the owner to post responses.

2013 Qubo 1.4 petrol had a failed B&M unit. A replacement B&M unit was sourced and fitted, and of course mileage is now flashing. B&M does seem to work for some functions.

A proxi alignment sees the B&M unit, but fails, showing all other nodes as good, but just states 'Failed' against the B&M unit. Mileage continues to flash.

Is this another broken B&M unit, or is there some additional procedure we need to follow to fix this?
