Just a quick post to share an interesting experience. I was changing the stereo and powered the car up with the dashboard trim and stereo removed to check new wiring before reassembling - doh, got the airbag warning light as the passenger airbag deactivated light was disconnected. Oh i thought, will need agcom to reset, tried the disconnect the battery for 10 mins trick all to no avail, airbag warning light stayed on. I have been really busy over last three weeks so no time to find a vagcom user, and lo and hebold after ~ 2 weeks and approx 1000 miles I noticed the warning light had gone off and stayed off, it has mysteriously reset itself - Yipee

So if you make a basic beginers mistkae like me, just drive around for a couple of weeks and with luck it will reset itself.
(I did upload a SC stage 2 map during this time but can't believe this would make any difference?)
Hope this experience works for others
Cheers
