I have a 2011 535xi. I have had it into the shop over a dozen times. I keep getting cold air blowing through my rear passenger vents when the heating system is on. I am being told that its to specification. This is bizarre. Has anyone else had this type of issue and what did you do about it? In my option list I notice that I have a S823A - Hot-climate version. Could this contribute?

Thanks for your help
