Sorry Typo,been on nights and had 1.5 hours sleep so am being a dozy s*d. Sorry I meant Airbag F/W upgrade. I dont think its a mounting problem,it just feels like the tickover is irregular,I was going to live with it but then the recall letter came so I thought s*d it and mentioned it when I booked the slot. Whilst I have your attention,could I ask you regarding a few other thinks that are bugging me? Do you think the ride is hard on your car? my previous car was a laguna and I think the ride on my C4 can be bone crunchingly hard,it seems to transmit every road imperfection straight up my back. Also ( and this is prob a little trite) I dont have an SX badge on the back,I have noticed some 1.6 SX with badges and some without (and believe me I have looked) at one point I had convinced myself they has sold me a 1.4 and stuck some alloys on it.
