Ok guys this is my third E60. Its an 08' 528xi. And the issue is my car takes too long to blow heat and defrost my windows It also fogs my left side windows while i'm driving. No messages or warnings. I have played with the settings in i-Drive checked the coolant level bleed the system. So I think my issue might be an ambient sensor or something like that. Please I can use all the help I can get Thanks.

 

If it takes long time to get heat in the car, thermostat may be stuck in OPEN position. Read the diagnostic codes via INPA.

 

How I go about reading the INPA codes? I checked my engine operating temperature and is at 71C (160F) is low i believe it should be around 90C (190F-200F) range so it might be an open thermostat Thanks PCY.
