Airbag light stays on
 

On my son't 2003 Allroad the airbag light stays on. I've read that it might just be a matter of disconnecting the passenger seat sensore, cleaning it and plugging it back in. I've found the connector, but can't see (under the seat) to disconnect it. Can anyone tell me how that connector comes apart? Do I squeeze it a certain way or is there a place to insert a small screwdriver and push or pull a tab?

Thanks

Is there anyone in northern Colorado (Fort Collins specifically) with VAGcom who could read and reset an airbag code for me? It is on a 2004 Allroad. I've done the TSB to clear the airbag light, but that didn't fix it.

Thanks
