Here what's going on, for no reason, since a couple weeks, my temperature display reading is totally wrong ... it's reading -49c when it's like +10c outside ... everything else is working fine ... I tried to reset it by unpluging the battery overnight .. the weird thing is that the temp reading came back fine for a day and then start reading impossible temperature again.

I hope someone have a idea of what's going on. Maybe the sensor went bad so if someone know where's the sensor is located, that would be a start.

Thanks

 

My car is a A4 b5 2000 1.8t Q ...

 

have you tried cleaning the sensor? maby a wire went loose

 

The sensor is visible at the lower grille on your bumper, it has a wire running to it and is located on a pedestal type thing.

 

Thanks for the reply ... I will look at it as soon as I have the time to go in my dad heated garage because right now, outside temp is like -10c to -15c ... you guys don't know how lucky you are not to live in Quebec, Canada !!

 

Not too great here in upstate NY. Got in the car at 5:45am to come to work today and it was 5F out.

 

Its a foggy and misty 58 degrees here.
