Customer: Hi, my name is ***** *****. I have a 2011 BMW 535i. When I turn on the heat, the engine
fan goes to high speed. when I turn it off or set to lowest degree interior temperature, the engine fan goes to normal speed. I am living in Vancouver, Canada. The outside temperature is around 0 degree. It seems only happen when the outside temperature is low. Thanks
JA: Thanks. Can you give me any more details about your issue?
Customer: my car's engine fan goes to high speed and loud when I turned on the heater in climate control (but engine oil temperature and coolant temperature are low or normal). When engine oil temperature went up to 120 Celsius degree, or I turned off the heater in climate control, or I set the interior temperature to 16 Celsius degree (coming out cold air) in climate control, the engine fan went to normal speed(no loud sound).
