    I've just had someone out to regas my aircon as it wasn't cold, he said it was low and isn't leaking when he pressure tested it but still isn't blowing cold. Found a code DF001 internal temperature sensor circuit. Where is this sensor?
     

  2. Did you find where this sensor was?

    It appears that I'm having the same issue!

    I think it's the one on the windscreen under the mirror but it didn't fix the issue, needed a new pump
     
  4. Ah right! Thanks for replying. That's a bugger.

    I'm not getting a error code but it's saying -24degrees on the obd scanner.
    I'll try it, but guess I'll probably end up the same situation.

    Pretty sure that will fix your issue then as I've seen others with that fault just change the sensor
