With respect the cause is irrelevant. The warning light is what counts. You should take your cars in to a Citroen dealer asap. It will fail the mot anyway, so you had just as well bite the bullet and drive safely.
both airbag warning lights are flashing on the cars instrument panel what could be causing this fault? if it is a fuse problem which fuse is for the airbags as it is not shown in the owners manual?
