Title: My Omega thinks its in Australia!!!
Post by: richardirv on 17 April 2008, 06:22:30
Noticed this happening over a few weeks, temp goes sky high then steadily comes back down to normal. Well now its just high all the time!! Usually between 49 & 56 ish. Thing is its also making the heaters not work right, can only get heat if its on High setting, blows coldish when on like 25-28.

Sounds like the sensor is either on its way out or there is some corrosion around the connections.  Have a look (behind the bumper I think)  A replacement one is not that much, I had a problem with a veccy one and replaced it with one off ebay and it worked fine...

Genuine sensor around £5 on TC.

I dont belive this has any control over climate.  That is a seperate issue.  Have you tried resetting climate? ( off ang auto buttons together for 5 seconds I think)

Almost certainly the temp sensor behind the front bumper, and yes it will affect your climate. Had a similar problem with mine although mine turned out to be a bad wiring connection on the sensor. Totally confused the climate control.

Yes it does, the climate uses the external air temp to get a view on wht the incoming air temp is.

Hence, if it thinks the outside air is 30+deg then when the climate is on say 26deg, it cools it by default.

 Odd... does that override the sampling fan?

*strokes chin* If I wasn't sitting here with a big tub of Milkybar icecream, I'd be out looking, I'd have swore blind I had one! But I trust you. :y :D

 *wonders if you can get stick-on sampling fan vents a la those fake sunroofs*
