[s-cars] Airbag light help?

[Rob Pecsar]

Steve,

I'm also working on '92 S4 airbag light that stays ON for 2 minutes.

The Bentley schematic had nothing on how to reset it. The Bentley did say for model year 92 to use airbag tool VAG 1619. I was not able to come up with info on this tool. Maybe you can...

However, I checked www.sjmautotechnik.com and it was suggested that the airbag "might" be reset if you disconnect power for awhile.  I plan to try this, by unplugging the red connector labeled AIRBAG located up under the right side of the center console.

I realize this isn't strictly an S-car question, but since they have the same airbag system, I'm hoping people may have BTDT, and be willing to help.

This work involved removing the airbag, steering wheel, steering column switchgear, instrument cluster, and lower dash pad (at the driver's knees). The job went smoothly. I carefully reassembled, and the key now springs back correctly to the "run" position after "crank", and the replaced bulbs work. BUT now, the airbag light won't go out. This last weekend I took it apart again to see if I could spot anything that would cause an airbag malfunction, and I couldn't. I did have the ignition switch on when the airbag was out to test the new bulbs.
