Hi, I have been using the precondition climate control which had been working fine but now I am getting the above message (or words to this effect) and it's not preheating the car even though it's set on the schedule. I've tried turning the settings off and putting them on again but no joy. I didn't use it on two of the days last week and the issue has been since then. Anyone know why and how I rectify this please? Thanks in advance.
