Airbag light stays on

I removed my airbags whenI was fiting a new heater core. Now, the airbag light is not coming off, even if the bags are both connected.Some please tell me how to install or reset them. The signal light to on the xtreme left of the dash, under the h/light switch stays on after starting the vehicle. Advice please.

You need a VAG or VAG-COM scanner to reset the air bag system.
