Euro Outside Temperature Gauge

mine is almost 1 or 2 deg different from the weather anouncement... so far so good

a lot of people complain about the thermo not reading 'accurately', but if you look at where it is actually located maybe that will give you an idea why it may be off a few degrees (near front licence plate in the grill).

yup. on a hot 30C day, the temperature gauge in my car was stuck at 24C. the outside air does fell like 30+.

the climate control, in debug mode, displayed the external temperature as 29C, which is closer.

the gauge was like that for about 1-2 days, but since that incident, things are back to normal.

That's odd because the external temperature in debug mode and the external temperature gauge run off the same sensor at the front.

Same thing happened to me. It was a hot day today. My temperature reads 24 degrees even the car was exposed fully to sunlight.

yup.. i thought so as well, but i had to switch off and start the car, unplug the batt to 'reset' everything.. but it does not help either..

it happened again today, temperature gauge was showing 26C, when it was very warm, the cc in debug mode, shows 31C.
the temperature gauge very very slowly climbed to a matching 30C eventually, about 4 hours later

In debug mode, while option number are you using to display the outside temperature? 1, 2 or 3?

I was under the impression that it is meant to be a rough guide to outside temperature and not that accurate? Also it depends on where you are taking the BOM temperature from, suburb to suburb obviously changes in temp.. also it depends on whether you are in the shade or sun etc so don't heed it too much it is just a general guide!

You car has shit loads of variables on it like engine heat, paint colour ,air flow, proximity to the ground....

Come on. Be realistic.

Of course I'm not expecting the gauge to be 100% accurate. An approximation is absolutely fine. I am, however, surprised when I start noticing a significant variation after two years of good accuracy from the system. A margin of error of 5+ degrees, combined with an unwillingness to change temperature despite reported changes in the air temp, tends to suggest a potential issue.

yfin - thanks very much for your post. I'll take a look tonight and see what the gauge is reading compared to an external thermostat.

Anyway, all I was looking for was an idea as to the general reliability of the gauge on other peoples' Euros. I'll check the gauge myself, and if it continues to read inaccurately, I'll have the dealer check the sensor at my next service.

u read my mind.. i thought i had the wrong debug number, double check, and it showed number 2 (outside temp).

Hi Mislovic, Aday,

I know it's been a while but were there any resolution to your temp reading behaviour prob? I'll be intrested to know, i think i might have just the same issue.
