Citroen C4 engine warning light & various others

Hi guys, my wife has just text me from work to say that her engine warning light has lit up and that the auto lock hasn't come on, and all seatbelt signs are still lit up.

I'm assuming that somehow they will all be connected, but can't find anything online about it. Any ideas? I'll know more this afternoon when she comes home.

Any advice would be great though.

Thanks
