I did find that the MAF sensor wasn't seated properly, sorted that now and the car seems a bit gutless. Before you could really hear the turbo whistle up but it doesn't now.

I believe if you haven't read the codes for a while you should clear them and re scan then after a day or two. By doing that you clear any codes that are still listed but no longer relevant.

Seen these codes a few times battery voltage is low or its been disconected at some point hence the codes on the engine and the airbag one,just re-set it and see what comes back as explained above!
