Audi A6 Airbag Warning Light / DTC 01218
 

This is just informative, for search engines. DTC 01218 is the code for the Passenger side seat airbag.

Have a Audi 1999 A6 Quatro and had the dreaded Airbag Instrument panel light come on recently. I didn't uncover anything in google related to Audi cars, but did get lots of VW hits. I found this web page below:

which I followed (although the AUDI wiring had slightly different color - but there is only one YELLOW connector under the seat and that's what I cut out.

Soon as car was back together, I reset the error, and it stayed off (at least for today!)

Hope this helps someone else!

Resistance measurement 2.6 ohms
 

I forgot to mention that I used an ohm meter to measure the resistance of the two yellow wires - I had about 2.6 ohms (which I understand is pretty good). People talk of using a 4.6 ohm resistor to fool the computer in the VW forums. YMMV
