That's more or less my next plan, but I need to be careful. The other car is virtually off the road until the rear axle seal is replaced and the rear suspension changed. I can't have two cars immobile.
The airbag light was going on and off, but now it's on permanently. When I checked the resistance earlier it was 4.6 ohms, but I could get it to change a bit by moving the steering wheel. Now the light is on all the time, I hope the resistance is steady, which might make it more traceable.
I had the clock spring changed in June and the new clock spring needs an adaptor cable. I'll have a look.
