Sat waiting to pick kids up the other day, showed Missus how to disarm passenger airbag, turned ignition back on lo and behold airbag warning light comes on :angry2: .Tried the usual stuff, moving disarm switch again but to no avail. Booked into "local" (30miles) Treg VW specialist as our local VW dealer (10miles) can't do warranty work!. Plugged into diagnostics an found intermittant fault on "drivers airbag igniter", Techie checked all connections etc but couldn't find anything and also did "unspecified" software upgrade on Treg at same time. We have now got to monitor the situation and if it recurs the Treg will have to go in for plus/minus two days for wiring checks. Checked the forum and found the bits about low charge on battery but has anybody else had problems with the passenger airbag disarm switch??
