Hi there, I have a 2016 business edition Superb 1.6 diesel . Every so often when I get back into the car I am unable to get the a/c to work. E.g. I may have had the heat on from that morning going to work. When I get back into the car to go home that evening, I turn the temp. Control down, but no matter what else I try the car will continue to blow out warm/hot air, as if it is still working on the temp. That was set earlier on that morning. I have brought the car back to the dealer and they tell me they can find no fault, but it's doing it again, albeit very occasionally. However it can be quite unbearable when your driving on the motorway on a sunny evening ! Any suggestions??
