ok thinking its going to have to be towed any way as its a non starter :(
You can loan one from your local library, whats the problem & how did the problem start? If you give some sort of info you may get a resolving answer Fire. The E46 is simular to the E36.

he fixed an issue then took it for a test drive and the whole engine shut down on him. there is a fuse popping on the system each time the go to test it. a friend is coming today who has better knowledge of the electronics on this car
It seems the issue he fixed is the cause of the problem! Alarm or immobiliser mabey?
Alternator connections?

BMW's don't just get a short in the wiring ..
He has trapped a cable under something or connected something incorrectly .. (or not at all)

turned out whilst tinkering he had put a wire to close to something which ran hot which in turned melted the wire and shorted the system. One former BMW mechanic (who specilises in electronics) later and four hours of ferrying bacon buttys and cups of tea problem fixed and car running like a dream!xx
