    The outside temperature gauge has suddenly started reading exactly 5 degrees to low, anyone got any ideas?
    It moves up and down as the weather changes but always around 5 degrees out.

    Thanks in advance for any suggestions.

    that's only 2.5oC, about right for snow melt.

    Cool, if you can find out which sensor it is then it would be much appreciated.

    No mate, 36.5 degrees C!

    That's not too bad, any idea which sensor?

    I plan to have a proper look on Saturday.

    Got the bill, they changed the Outside Temp Sender (A8Z0 820 535) cost £17.95 for the part and they charged me 18mins labour to change so must be an easy job.

    Right I think this is the temp sensor, near-side and behind the grille:

    is that right anyone?

    If it is it's a defo bumper off job!

    As they charged just 18mins at garage I doubt the bumper has to come off, must be a simple unplug and replace.

    That's why I'm confused. A Google image search for outside temp sensor brings up sensors that look like mine above but there's no way I can get to that sensor without taking the bumper off. I know it's in slightly different places for different models but I want to be sure before I start taking the front end off!

    I think the A3 is in the wheel arch so wheel off and change, whereas the S3 is behind the grill - hence the bumper off!

    Staz - Did you ever get this sorted? Was it bumper off?

    Although I have replied to your PM James, I will reply here also for others to see.

    I hadn't got around to sorting this issue but it seems to have fixed itself now the summer is here.

    It's definitely the right sensor though and you'd need to take the bumper off to get to it.

    Thanks matey - i took a quick look last night and tried to contort my arm to get in from underneath etc but for the sake of my blood and skin, I will just remove the bumper.
