seatbelt indicator light always on

There is a problem in the SRS system which requires a computer diagnostic. I suggest to find a good VW specialty shop, they should have the equipment to do this. It could be a simple thing as a micro switch in the belt latch... Zee

I think there is problem in the SRS system, you can find some DIY diagnostic tool to repair it, I know some VW tool, may be they can help you, or maybe you can find the VW expert garage to repair it.
