Help/advice urgently needed please.

Hi All
I have an issue with my passenger side front door. I just went to lock the car and the alarm wouldn set as I now know It couldn't find the passenger door. It is completely dead, nothing works ( mirror, window, lights etc) and it will not open from the inside or outside. It won't work from the drivers door controls either. So very inconvenient but the worst is I've got the MOT due on the 9th November and it's obviously a failure with the fault. I've no access to VCDS so had an Audi tech come and scan the car but with an Snap on scanner. First off lots of faults recorded for the door so cleared faults and rescaned. Door was not even found on second scan.
So my thoughts are; break in the wiring to the door, or the door module?
Do any of the more experienced amongst you know if there is a way to get into the door to open it without destroying/cutting off the door card? It seems to be the only option open to me that I can see.
Any suggestions are very welcome
Thanks for your support in advance
Cheers
