let me know how you get on, same thing happened to me about three / four weeks ago, driving along one day and ping on came the airbag warning light, I think it must be the seat conectors (as I swapped cloth for leather seats about 10 / 11 months ago), so I disconnect the passenger seat airbag connector and reconnect it and pop down to my mate who runs a light commercial garage, he has a multi marque diagnostic tester, not as good as VCDS but it did tell me that the fault was passenger side airbag igniter, didn't say if dash, curtain or seat, so I clear the fault using his tester and happy days it stays out - for a week - and then ping back on again :( been on since as I've been too busy to do anything about it.
Basically the car starts, then it does its self diagnosis and ping (with audible warning sound) on it comes without fail :(
What do you reckon, airbag in passenger seat needs replacing?
Car is a 55 plate and long out of warranty, anyone any idea if it is a DIY, indie or a main dealer and will it be lots........£££
