Sounds like something happened to the wiring harness in the column. The air bag circuit is in a different harness.

Disconnect negative battery cable. Locate airbag retentions on back of steering wheel. Unbolt or unclip retention devices, and release airbag. Then: Unplug airbag electrical connector. Remove nut or bolt in center of steering wheel with pneumatic impact wrench if necessary . Using appropriate steering wheel removal tool kit, carefully remove steering wheel, paying attention to associated wires, etc. Unplug anything not accompanying wheel, or that is in the way. Pay close attention to any rods, or contact pieces associated with the horn button(s.) Replace these upon reinstall. Reverse order to install including tightening center bolt to 35-55 ft-lbs. If this is your first stg wheel removal, try an old chevy, preferrably someone else's! If inexperienced, don't risk bruising your favorite Bimmer!!! Hope this helps you make your decision. Tater Todd

This is due to a broken clockspring behind the steering wheel. It works as a constant contact for all acessories on the steering wheel to include the air bag system. It is a simple ribbon of wire to allow for turning of the wheel incased in a plastic housing that shouldn't be messed with. If you mess with it internally, you run the risk of the airbag deploying in your face!! It is best purchased from BMW.
You must emove the air bag in the steering wheel to get to the clock
spring. Unless you feel you understand the air bag system 100%, and feel
comfortable disconnecting the air bag, I suggest you take it to a professional for repair.
This is not hard to fix. The Airbags are already disabled by if your
airbag light is on. This is done automatically when the system senses a
fault to protect occupants. What you have to do is unsrew the 2 screws
on the side of the steering wheel and then remove the cables that go to
the airbag and cruise control. Then you need to unscrew the one star
bolt that holds the steering wheel in and use a steering wheel pully to
pull off the steering wheel and there should be 3 screws holding the
clockspring in. You need to remove the clockspring and replace it with
one from the junk yard. Theres no reason why someone should charge you
for more than 1 hour labor to do this. It doesnt take longer than that make sure you dissconnect battery first before you do this is your air bag light staying on370 views
