ok guys, I removed the instrument cluster of my 406 to check what is going on with the bulbs,
(not the easiest thing of the world though...as the cluster is a little bit tricky to take
it out even when all the screws have been removed... ).
Here is a photo of my instrument cluster... I numbered the bulbs that I was able to identify according to the
list I posted in my first post. So from my previous post we have:1
. Passenger airbag disarming warning light 2
. Diesel engine preheating 3
. Battery charge warning light4
. Engine diagnostics light 5
. ABS system warning light6
. AIRBAG warning light 7
. Engine oil pressure light 8
. central (STOP) warning light9
. Hand-brake and low brake fluid level warning light
As you can see the "battery charge warning light" bulb (No. 3) is missing.
What I did is that I used one of the bulbs as my testing bulb and I begun to populate the empty positions
which I marked with the letters "c?", "f?", "g?"
, hoping to find out if any of them are the bulbs 1 and 6 ("passenger airbag disarming warning light" and "AIRBAG warning light).
Well they are not or they simply don't work.
I wasn't able to identify that bulb with the black holder that I marked with the letter "a?"
It's a mystery as well what the bulb marked with "d?"
During my test I turned on all the electronics of the car that I'm aware that they have indicators in the instrument panel
(lights, hazard lights, etc...) but still I couldn't identify what the "a?" "b?"
bulbs are for...
Anyway, what bothers me now is why the 1 and 6 indicators don't work (the "airbags warnings" ones...).
Is it possible that someone somehow "hacked" the ECU or the BSI so that the airbags warning lights do not come
on under any circumstances??
FYI, these are the kind of bulbs my car uses for illuminating the instrument panel and its warning lights.
The writing on the very thin bulb says: OS 12 3 W9S (i am not sure though, it's very difficult to read those damn miniature bulbs...)
