My Airbag light has been on ever since I bought my '05 R52s, and I finally took it to a shop to have it scanned. The code that it came up with was "Ignition Circuit ZK0 Airbag Driver Stage 1", which they said might be a bad clock spring. That would line up with my horn/cruise control/media controls not working. I looked at RockAuto for a new Clock Spring, and I'm not sure which one to get. I have the Multi-function steering wheel if that matters.

Which one should I get?

 

For what they want for either of those clock springs, I’d pull it apart and have a look in there before I put my money down.

Please keep in mind there are certain precautions to follow when working around an airbag. A good service manual will guide you through it.

 

Once you have a look, if a part is needed, you an find the right part number at realoem.com. punch in the last 7 of your VIN.
