1986 BMW 325

Computer problem
1986 BMW 325 6 cyl Two Wheel Drive Automatic 140000 miles

I just bought this vehicle from a friend and drove it home, not aware it had an anti theft device as part of the on board computer, I pushed the code button. And someother stuff. And now it wont start. I accidently engaged the anti theft mechanism and no one knows the code or what to do.I am completely lost and can't drive my new/old car because of this. Any ideas on how to reset it? Is there any thing I can do other than towing it to a repair shop? Thank You

Pull fuse 21, it will clear the volatile memory of the OBC with out taking out the radio code. If that does nothing, it may be the relay contact in the on-board computer relay box, I just jumper around it.

Could that solution also work on a 1992 BMW 325is? Same thing happened to me ; (
