I've removed various air bags ect, if one is inactive the rest will still deploy in the event of an accident they are independent of each other.
If you code one out or switch it off in vag com the start up checks will still notify the driver each and everytime but the light should distinguish. If the light stays on then one of the circuits have a break, so there are various way to troubleshoot it with a meter or simply a bit of wire but the easiest route is to get someone with VAG com to plug in and see which on it is.
check the connectors under each seat as they are the most common ones to develop a fault, the rest are all covered up behind the dash, carpets. door panels etc
