Hi, wondering if anyone can help ? I replaced my interior with s-line headlining today so had to rip pretty much everything out & unscrew the rear seat belt bars in order to thread the seatbelt through the new b pillars. I also replaced the main light switch in the centre with a newer unit, but this didn't have the passenger airbag warning light but had the same plug. Now when I fire the car up the AIR BAG light stays on. I'm taking it to get eibachs fitted & rs6 alloys tonight, but wonder if anyone knows if I've done something obviously wrong to cause it to come on ? I didn't disconnect the battery during this & was very careful around the roof airbags. Any ideas ?
