I read the codes on the car and found this. The Internet doesn't make anything clear about what this is. (I've never heard of a radiator blind or its function).

BMW X5 Cabin heat does not work Dear All I have a BMW X5 4.8L 2007 model with 210,000 KM on the clock. I have a problem with my car cabin heating system as it does not heat at all when set to heat settings. The fan works and the AC system cools perfectly. But the cabin heat does. BMW P152B code Hi. 2006 BMW X5 4.4i Getting a P152B code.

1. 2005 BMW 330i ZHP 2004 BMW 330Ci ZHP A DIY Turbocharger Project! More code that's not in the 0PA or 0DA. 2F99 1F20 2423 4400 111E 111F 0000 0111 0000 2F09 1E1F.
2. Rpm's are going up and down all the time, engine power reduced! After scanned we found following codes: (2CFB) and (2D09). Throttle body has been replaced with used one. Codes cleared also. But after restart engine again, same codes came back! Any help please.

I cleared the code and the reader said it was successful, however, the code came straight back.
About 3 months ago I had water pump and thermostat replaced, this is the first time I've read the codes since and can't confirm whether the code was present before.
I understand the car should run up to around 103 ish degrees when on a decent run to aid mph etc, however the temp in hidden menus only gets to around 78 degrees max when driven at 70mph gently for a few miles.
When I give it some beans, the temp drops significantly.
