I had the airbag warning light come on about 3 weeks ago in my 2016 Ducato 130. Seems to be a common problem. Took it to Rodney at RDO Auto Electrics in Killinchy, Co. Down. Used his diagnostic computer to find a fault in the airbag control module. He ordered a new one, then fitted and re-programmed it today. Part was £190, his labour was £90. Considering Fiat charge £85 just for the diagnostics, I think I got a good deal. Can’t recommend him enough. Great service.
