Got the same fault with my
mk2 Ibiza, but this was due to me turning the ignition without the airbag plugged in, now its permanently on.
After PM's with Scotty_b, he advised me that after an ecu reset (battery disconnected for 20mins), after 50 restarts, if the fault doesn't reoccur, it will clear itself.
I'm yet to try it, but not going to do 50 restarts in one go! Got my MOT on Saturday, will just remove the bulb for the time being.
Anyone tried and tested this method? I'll be delighted if it works, as I don't want to shell out £35 to a Stealer, or a tenner to local mech.
