I have 2 A6, A 96 I drive and a 95 for parts that I probly shouldnt. Recently checking and pulling relays in 96 and since have airbag light come on for approx. 2 minutes then go out. The other day I was checking relays in parts car and now that one does same thing. Relays were in black box near firewall driver side (high speed fans ect). Is there any reason that pulling that relay would cause this even after they were put right back? Thanks
