I'm not a mechanic but have a few BMWs and have tripped the airbag light(s). As you probably know, the seats have sensors and are integrated into the system, and disconnecting them can trigger the light. Often you can avoid that by disconnecting the battery first, but that's water under the bridge (and doesn't seem to be 100% dependable). Good news is that there may well be nothing wrong with the system assuming the wiring is the same (and the connection is solid). Bad news is that for cars after 2002 or so, resetting the light takes diagnostic software (there are cheap SRS reset tools for the earlier cars). If you don't want to invest the time and cash to learn diagnostic software (i.e. INPA, etc.), I'd take it to an independent garage that works on BMWs and pay them to diagnose and reset it, or to at least reset it (NOT THE DEALER--$$$). If there's a problem, the light will come back on. Obviously, you don't want to fool around with the airbag system, so worth being extra careful and making sure it's OK.
