Good day, I recently purchased a beautiful Alabaster Crossfire from a dealer and on my first road trip I noticed the airbag light came on and remained on, no blinking or pulsing. This is the light to the left of the fuel gauge, not the one north of the gearshift. I've been combing through the forums here and it sounds like this is a rather nasty issue that requires a Mercedes Star Diagnostic Tool. From what I gather, my only option is to have a dealer reset the light (~$110).

Not wanting to set foot in there, I took it to a mechanic with a DRB III tool who was unable to get into the system but suggested the issue could be with the passenger weight sensor, as the airbag off light (north of the gearshift) is dark with nothing in the seat. I didn't see anything in the manual about a weight sensor, and since we (US owners) have a keyed on/off switch that would seem redundant. It does appear the seats are wired to the restraint system, but I believe that would just be the seat buckle contact. Do we have a weight sensor? I'd hate to have the dealer take me for a ride selling me one if all he does is reset the code.

Any other ways to clear the light would be greatly appreciated. I'm not overly thrilled with shelling out more cash to fix a dumb computer issue.

Thanks all!
