After many shennanigans after my passenger side door lock failed whilst deadlocked on my 12-plate Octavia estate, I now have an airbag warning light showing on the dash.  I thought I'd check with my OBD2 reader to see if it could tell me any more, like perhaps which airbag it thought was at fault.  My reader however reports no error codes at all.  Does anyone know if that's expected for this particular age/model?  I have a feeling that airbag systems did not always report faults via OBD2, but I'm far from certain.

 

Meanwhile I shall be trying to check all the connectors manually having read through a few posts here about possible locations of connectors.

Be careful with connectors. I would disconnect battery first and leave for a while. Its weird that there are no error codes unless your reader isn't compatible with airbag system for some reason. If the light is on then why no code? Is the light dim or the same brightness as everying else as there have been a good few falts on here that have been down to poor/loose connector at rear of dash causing random lights to come on but not full brightness. I had DPF,Airbag plus foglights and a few others.

The light is bright.  It goes off briefly after the ignition is turned on and then comes back on again so I'm not immediately inclined to believe there is a connection fault in the dash.

 

Looks like there are quite a few OBD2 readers that don't say whether they manage airbag codes (and some usefully say that they definitely don't).  I suspect mine may be in the first group and I didn't pay attention when I bought it.  I'll look for another.

Might be someone close to you with vcds or similar? If the light bright aand goes off and then on its probably not the dash.

Good point.  Anyone in the Taunton (Wiveliscombe) area who might be able to help?  Sadly I can't bring the car to you as it no longer has an MOT and, even more awkwardly, appears to have a dead alternator (which might actually be the cause of the airbag issue in the first place, I guess).

 

Meanwhile I shall go back to looking for a reader that might actually do the job 😆
