307 2002 1.4hdi steering rack was leaking from the offside track rod into the boot because there was play on its bearing/bush. I asked my local friendly garage to undertake this job due access and subframe needs lowering to change it. After it was done I went to pick it up and he said the airbag light was on and do I want them to fix it. I replied it was not on when you started the job and as you have had the steering wheel off then the likely hood is that is what has caused it to fail. It turns out that whilst the rack was off the steering wheel must have been turned as something he calls the clock was damaged which obviously engages with the airbag somehow! I have looked in the Haynes manual and cannot find it mentioned either in the airbag removal section or the steering rack section. I believe it might be a plastic cog or something and that once the rack is disconnected the steering wheel has not got to be turned. Anybody able to enlighten me more of the setup. I am awaiting the garage to receive the spare so that they can finish the job. He understands it is down to him. He has just employed 2 new fitters and the one who did the job insists he did not turn the wheel!!
