Hi all,

My Skoda Superb 2 2008 TDI, whilst driving, popped up with an airbag fault.

VCDS was connected and all of the crash sensor sub systems were showing “000000”

Does anyone know what would cause this. I do not have VCDS but have a friend that does. Has anyone come across this or know where to start so that when they next come round we have a good place to start fault finding.

Thanks all

Check for broken wires in bellows between A-pillar and driver's door.

Thanks for the reply Pete. I did check the drivers side (all ok), and I will passenger tonight. I removed the steering wheel airbag, all visually ok. Clock spring looks sealed and undamaged (all buttons and lights work)

It is showing for all crash sensors, not just in the doors.

Is the airbag loom or SRS system on a LIN network? The loom going into the module behind the dash on the tunnel is fine and undamaged.

Yes, worth a look at passenger side too. Wiring diagrams refer to G179 being driver's side, but the connector the wires go through on the schematic is described as "T28a 28-pin connector, on the left A-pillar" which would clearly make sense for a LHD car, but not for a RHD.

It could be that the wiring diagrams are just wrong for RHD cars, or it could be that G179 and G180, (its passenger side counterpart) actually do stay in left and right doors irrespective of LHD/RHD.

Wire colours from G179 are shown as green going to pin 15 of A-pillar connector and brown going to pin 16. For G180 these are red and brown respectively.

It would be handy to get confirmation of what colours you see in those positions on nearside and offside of a RHD vehicle.

Pinout of connector shown here, viewed on mating face. The fact that they are at opposite, extreme ends of the long connector perhaps adds to the likelihood of strain and breakage.

Hi Pete,

Thanks for this write up!

I decided to take a punt and fire the parts cannon, changing the airbag module as it was only £14 on eBay for a used one. Was the same part number etc. Changed and all went away, verified with VCDS, all the crash sensor serial numbers came back etc.

Did a few power cycles and ignition on and off and was fine. Checked with VCDS and again, all good.

Looks like it had an internal fault or corrupted itself from one of the many potholes in the UK haha.

Thank you
