Airbag warning light after shunt

[GarethP85]

Hi Guys, 

Newbie here asking for some advice! 

Stupidly this morning I ran into the back of someone. Only in traffic so no damage done to either car (unless she decides to put a claim in I guess! ) 

However, I got back into my car and now the amber warning light is on for the airbag. From what I can see it seems like it just needs resetting as it didn't deploy but there was a collission? Anyone else had the same that can offer some advice please? 

I've just ordered a Carissta VAG kit - will that allow me to reset the code? 

TIA
