Look *look* a post to a.a.a-r

That makes two in one week!

Seriously, my car, this morning, reported the outside temperature as:
36C, 11C and then 13C

I'm *reasonably* sure this is incorrect, especially as I can still see
snow outside.

Is the exterior sensor linked to anything important in terms of engine
management / consumption?

TIA

Not AFAIK. Might be linked to the climate, but unlikely on a 156 as the
cimate is nowhere near as advanced as it is in a VW, which does use the
external temp. sensor as part of its calculations.

Well, the climate is definiteley keener at blowing air out. It's not so
keen at keeping it warm, but liveable.

It seemed to be sorting it's ideas out on the way home.

IIRC, below a certain outside temp (5C?) the compressor won't run but
I think that's as clever as it gets.

If you mean it's keener at blowing chilled air out, that may be
because the compressor is running when it normally wouldn't.

The temp sensor is in the passenger side mirror..door wiring harness
chafing?

Nah, it's just keener at blowing air out when you start the car.
Previously the engine had to get warm before the blower would kick on
(when set to auto and high temp)

Now the blower blows almost immediately, and the air that it puts out
gets hotter with the engine IYSWIM

Could be, though the trunk looks OK.

It's a very minor annoyance I think.

Was the wing mirror (temp sensor) in the sun, but out of the wind?

Ah yes..I see. That's the only other bit of Alfa CC cleverness. When I
get out of work on freezing nights at 01:00, it can sometimes take 5
miles before I get *ANY* air out of the vents. For some
direction/function settings, it can be keener to blow earlier. I think
the Alfa CC is cleverer than anybody (including the designer and
definitely including qualified Service mechanics) knows.
