I'm not sure to be honest, I've never had an airbag/SRS light come on. It does struggle to recognise some of the body systems on my Alpina but it does OK with the 330. I don't know if it's worth the risk, you may spend £100 and find it does everything except what you need it to do. The good news is that if you can get into the airbag system like I can on the 330 then all the functions including erasing codes within that system are available to you. If your ever near Bristol you could give mine a try before you commit to buying one.
