Are you using the stock seatbelt receptors with your new (aftermarket?) seats? A disconnected seatbelt receptor will turn on the airbag light as well. Keep in mind that using a VAG-COM is the only way to actually clear an airbag light, you have to go into the airbag module and clear all faults. You can't just do a general code clear or disconnect the battery to get it off.I don't have a VAGCOM there are just enough floating around locally that it's easy to get the car scanned by someone. I don't know what else would trigger the light as it was not on before the seat install.
I figured that it is probably just not a good connection and that I have to fiddle with it. As simple as this is, my history with messing with the electronics on this car isn't stellar so I figured I'd see what bonehead mistake I might have made. Thanks for the helpful reply!
