Hi All
It took a while to wait for a climate control unit, which did not work properly and had to be changed. Now it has been changed by a professional local BMW service provider and the heating/air condition works fine. The temperature here has been last couple months nearly all the time below minus 10 centigrate. It has been nice to ride in a warm car wihout frozen windows. In couple months the weather will get warmer and in round 5 months from now also the cooling of a/c will be needed.
