Having a random issue with the seat belt alarm on my Beetle. Get in, put on belt and off I go, everything's find. However at random while driving the seat belt alarm will go off and the light on the IP lights up. Only way to clear is to unbuckle, then re-buckle. This is VERY random. Took it to the dealer and of course they couldn't make it happen so "we didn't see anything wrong" (yeah, troubleshooting is a LOST art) so they couldn't fix it. Any ideas? Anyone else see this issue?
