1989 e34 525i
Only way I could get my back door open was to take out the back seat, remove the door seal and take the inner panel off after winding the window down. After taking out all of the screws I unclipped the top of the panel then used a long flat bar to pop as many of the trim clips off as I could , and then pulled the panel up quite hard. Some swearing was involved. However this was caused by a seized central locking motor not a door mechanism problem. Front door could be a bit harder
Have you tried re-synching your central locking?
Google BMW E34 door lock problems there are lots out there
My daily is a Mitsubishi HSGR (but I wouldn't mind an e34 525i)
