Re: ALFA 156 Airbags
i am no expert, one will be along soon, but there may be a difference between pre-02 and post-02 cars.
I know i have an amber light which is my passenger airbag light, its to show if it is de activated using your key beside the glovebox, ie; for a childseat.
this light should go out if normal and stay on if you have disabled it.
if its on all the time, check the keyhole is not set to off and swith it on and off anyway to see if it helps.
no clue of your actual red light, it could be any of the airbag sensors sending a dodgy signal or a loose cable with any airbag, its usually the passenger seat sensor connection.
*all this advice could be completely wrong, i've not looked in the book for a while and my lights are out, touch wood!
