Hi all,

I took my steering wheel off to replace the bulbs behind the dash dials. When I put it back on I somehow managed to trap a brown wire and snap it. Shocked (This wire goes into the steering wheel)

I repaired the wire, put everything back together and now the airbag light on the dash stays on. I've replaced the steering wheel airbag (the whole centre of the steering wheel) and the airbag sensor unit behind the centre console (and what a job that was!) but still the light remains on. I've even disconnected the sensor which didn't change anything.

Has anyone got any ideas? I'm a bit lost with what to try next.

Thanks

And just while I'm on, does my car have any kind of diagnostic port. I think it's in the fuse box but what attaches to it to read/clear faults?

Thanks again

there's 2 ports in the fuse box (actually 3 but you only use 2). You'll need a 2x2 adapter



That brown wire is for the horn I think.

air bag fuse ok ?

I've heard of it sometimes clearing if you go for a drive of 20 mins +

Thanks Mike. The cars not been driven since the light came on. I'll give that a go and check the fuses.

So the fuse is good. When I disconnect the airbag from the steering wheel and disconnect the sensor in the centre console the airbag light stays on. So even if I removed the whole system including the wiring (not that I would) the light will still be on. What's telling the light to stay on and how do I stop it?

If I can't get this sorted it won't pass an m.o.t. and I'll have to consider getting rid of the car. Can't imagine my other half will want it blocking up the garage!

You need to read what fault codes you've got. If you have removed the wheel you might not have any faults, you just need to clear the codes and all will be fine

Thanks for the reply. So what do I need to do that. The code readers I've seen online only seem to read and not reset.

Im not sure what code readers work! quite a lot will read the fault but not clear it (air bag faults mainly)
You can download a free VAG system on your computer i think, you will still need to buy the leads.
The little hand held MAC one we have got at work didnt work on my C4 S6 last night.
Ive brought our SNAP ON SOLUS home tonight because i know that works.

So ordered one of these. Comes with the adapter cable. Fingers crossed it works. I'll post when it arrives and I give it a go.

Got no idea if that will work but fingers crossed it does. My car has low resistance on the drivers side air bag. ie hopefully a dirty contact on the plug!!!

No idea if it will work but it's worth a try. Running out of ideas.

For some reason I can't upload the photo. I plugged the reader in and it gives me this.
Code 588 - 161 KWP1281
Airbag igniter drivers side (N95)
Sporadic - value of resistance too small

I guess this is a connection issue somewhere in the airbag system? Any advice appreciated. Very Happy

Just thinking. The brown wire which was severed was soldered back together. Could this be the problem even though it's for the horn? Searching the www lots of comments about the click spring causing an airbag fault code and the brown wire does go into that area?

Not one to hang about I re-did the soldering. Put it back together and cleared the fault. Hey presto, it's gone. My dodgy soldering to name!

Thanks for the early help guys. salute

Good you have got it sorted. It was always going to be a simple fix if the light wasn't on before you removed the steering wheel.
Have you got a link for the fault reader? how much was it?

Thanks. I got it on Ebay. If you search for Vgate scan tool you'll find one. I paid 27 but that included the 2x2 lead I needed. Just out of interest I tried plugging it into a 2008 Saab and it communicated with that as well.
