Hello one knows a tip how I can check what is actually defined? The following happened and I did: Fzg was warm driving in one day with approx.25* until then no problems exist. Fzg switched off about 15min restarted Airbag control light no longer goes off. Watched on 5 days, account lights constantly. Error read out, message “Zündpill resists too high driver side”. How can I check whether the airbag or the wivel spring or,or is defective, without which the airbag explodes? Best thanks already in advance, and smart greetings
