Whilst changing the fog lights on my E36 this weekend (thanks for the
tips on this, I will be putting up some photos of how to do it at some
point to help the next guy), anyway, whilst doing that I was poking
about and found this sitting on the inner wing, rattling about.
It has no markings, no part number, nothing.
After a bit of poking about, I found another one on the other side,
this one was still fixed to the inside of the wing, just behind the
turn indicator. If you weren't looking for it, you'd never see it.
Does anyone know what this thing is? My car is a '96 325 TDS SE, and
it doesn't have the blown lightbulb check system, so it's nothing to
do with that. It does have headlight washers, and the electrically
adjusted headlamp up/down control by the steering column.
It's about 2.5" x 1.5" x 3/8". It's completely black, no markings, and
all the wires are brown.
Can anyone shed any light? I'd like to know what on earth it is.
I also found 2 sensors in some air ducting that leads from the front
grill through to a hole in the front of the wheel arch liners. One
side had a long thin probe that stuck out into the air flow by about
1", and the other side had a big round one that just sat at the side,
it was about 1" diameter. I guess they are temperature sensors, but
why should the car care? And why does it need 2? Surely the air coming
in on one side is the same temp as on the other!
Anyway, thanks to anyone who can tell me what these things are/do.
