I lost sound of the horn and i have an orange light in dashboard associated to airbag - i have checked fuses but and changed them but that is not the problem

what can it be please?
i have been suggested the o ring behind steering wheel if it is so what is the proper name ? Also if it is that , mine does not have any steering wheel controls (radio control or cruise control, volume, source etc) can i use one O ring ( please note i need the actual name of this) from a skoda octavia same age as mine or do i need one from a car that does not have controls as mine
thank you in advance

Yep, probably the clock spring assembly which keeps these functions connected when you turn the wheel. Search for post using clock spring.

Just noticed that this is a duplicate thread, two hours after you posted

Airbag warning light and no sound of the horn- both lost simultaneously- what can be the problem ?
