Temperature sensor in the mirror

[djheath]

Hello, I noticed yesterday as I was freezing in the british spring, that my outside temperature on the mfd was showing as 24 degress C! I knew this to be completely incorrect and thought it must have just been sat in a hot spot. On driving around a bit, it went down to 22, then jumped to 19, then back up to 24 again, all within the space of a few minutes. It did the same again today on the way to work.

Would the problem be with the sensor in the mirror, or is there somewhere else I can look and fiddle around with? I also assume this reading incorrectly wont have any negative effect on the running of the car?

It is 1999 D9 with climate control, if that matters.

Thanks.

Most likely the mirror. But yesterday was a warmish day all over the UK and Ireland. If it went down to 19, thats about accurate. When the car is in a hot place for a long time it always over reads. I dont think its faulty. Mine was reading 18-21 yesterday

In Ireland?! I think yours is faulty too! :D

I don't think mine is right to be honest, since it was still reading 24 degrees again this morning at 7 am, overcast and cold to me! The weather forecast for my area says there will be highs of 9 degrees today!

I will keep an eye on it. Maybe I am being paranoid.

Oh really? Then it is faulty. They're not too expensive new from the dealer.

Ya the weekend in Dublin was fantastic. I got some sunburn too!!!

Mine has been reading like 2 or 3 degrees when I start the car, even had a frost warning last week but after about 10-15 seconds it finds the correct temperature.. or what I think is the correct temperature.. around 10-12 degrees

This must be a trend, I had 24c last night in balmy Surrey! (not)
The sensor is pretty cheap, when I replace mine I'll do a "HowTo".

Thanks, that would be great. It was 36 degrees this afternoon!! Think I might have to get the bikini out at this rate!!

I could see the little "nub" of the sensor sticking out the bottom of the wing mirror and gave it a wiggle, but no changes so, thinks it's on its way out.

Thanks all.

Anybody got a part number for the temperature sensor?

haha that's a bit of luck, you can't be too careful about that ice

Mine's all a bit mental too, got in the car tonight and it reckoned it was 56c ! Lol i know it's always a bit warmer down 'ere in the south but it ain't that warm!

I remember around the first time I got a 406, I got the ICE ALERT message on the screen. I originally thought there was some reciever on the car that got local weather reports.
