Happens when the vacuum lines are not sealed.
Suspect perished diaphragms in the locking actuators in cars of this age.
The pump runs on until it either locks the doors normally if all is working, or times out after about 30seconds if there is a leak.
It's relatively easy to isolate the lines to each door, to establish which one is the cause. Start accumulating spares from scrappers.

Okay, car was booked in for some bodywork with Audi back in 2000, a week before it was due to go in, some a***-**** decided to take a liking to it (and several other cars that night I might add). Anyway, in addition to the insurance claim, Audi also arranged to have a cat1 alarm/immobilser fitted for me. Had a few issues with it initially, it's very advanced n confusing at that, but the chaps that fitted it have been extremely helpful in showing me how to programme it, and even supplied me with the installation manuals for it some years later in view of the system being discontinued.
Cant honestly remember when I noticed the pump running on issues, but I had the pump checked out last year (nought wrong with it), and also disconnected the fuse to minimise battery drain, but I've not had the cash until recently to get it fixed; is on my to do list for this year though.
Furthermore, I'm aware that the pump problem could be related to a vacuum issue/accuaters, but I've absolutely no idea where to start, let alone how to isolate each door. Trying to find my car model in a scrapyard around here is virtually impossible too; I did find one about 7yrs ago as needed a column switch, was miles away, but I picked up the part and fitted it myself, albeit that I had to borrow some tools to undo the steering wheel bolt, but hey, was fun. ;)
