Default Does no-one know the answer?

The guys at A for Audi tried a brand new sensor - still no luck. I've tried 3 sensors now and checked that the connection below the n/s headlight is good. But it still reads -40C every time I turn on the ignition and takes around 10 minutes to get to the 'real' temperature. And then it seems to work OK until I turn off the ignition again, when it goes back to -40C and again takes 10 minutes to read correctly.

Are there any auto-electricians out there who have any ideas?
