Now thirdly it seems i have an issue with the heating dial. When I turn it to 10 o'clock it almost gets stuck (as if there is something wrong with it). I can force it through further to the right but it feels like something is going to break. Then it works fine after that again but I am definitely taking it back to the garage when I have time.
I guess you mean when turning clockwise? Ours do that too, though never so bad to think it will break. Its seems worse when it is cold or when the vents are cold (with aircon on).
