Airbag warning light

Get the codes read, that will give you an idea of the problem, it may just need a reset. Airbag light on is not an mot failure. Yes, it may well be an expensive thing to fix, but it might just be a bad connection or a wire pulled off. many people would just disable the light, that is up to your conscience.

The often quoted cause is the connectors under the front seats, that go to the pre-tensioners. It would be worth disconnecting the battery for 30 minutes or so, before playing about with them though. I had a similar problem with my Rover, which turned out to be the rotary connector behind the steering wheel.

First thing you need to do is get the fault code read, it might have been a temporary glitch or it could be much more. I'd make a small wager it's a dodgy cable or connector.

Ah, I did move the driver's seat quite a way back the other day, which doesn't happen very often, so maybe a connector for the seat-belt pre-tensioner has gone AWOL (he said hopefully!).

Cheers.

Indeed. Which is why I'm asking you lot who may have more experience of these things!

Yup, that happened to my laguna.

My mother's Saab developed an intermittent airbag light fault when wiring under the passenger seat was disrupted by stuff being packed under it and the seat being moved rather unceremoniously, breaking a wire or 2.

Experience dictates that you need to read the codes or you won't know which connecter to go hunting. YOu can get VAG code readers/resetters on Ebay fairly cheaply or just buy Vag-Com for the easy life/ lets you fix everything else. (Yesterdays A4 airbag was an intermittent memory check fault internal to the controller so by the time you've played with all the connecters you'd probably create more faults).

Having said that the odds are you've bumped the pretensioner lead.

Proably the wirng loom/connector to the drivers seat, but you need a code read to check.
