2009 Skoda Fabia 1.9 Diesel Electrical?? Issue

Hi everyone - I have an issue with my trusty & ultra relaible 2009 Skoda Fabia 1.9 Diesel.
All of a sudden (no rhymn nor reason to this) all the warning lights come on the dash (you can be driving or not) and you loose power brakes, steering, air bag waning light comes on, etc).
Ignition off & back on and the cer behaves as you'd expect - but the AirBag light remains on.
Here is a copy of the AutoScan

New car electronics are not my strong point, so wanted to pick the combined brain of the hive mind to see if you can assist me in rectifyiing this fault.

Many thanks
