I am really grateful for all your advice but, after another couple of hours trying all the things suggested, we still didn't manage to do the proxi alignment. As suggested, suspicion lies with the cables/connectors as clearly other owners have succeed with the same job using the MES software.
So, rather than my campervan be out of action for too much longer I have sent both ECUs to Crash Data to use their proxi alignment service.
It seems a shame to have given up after all this time but I just want it sorted now.
