Mein Auto: 2007 X5 V8
@brown370 I know I am a little off the topic here but I want your advise on one thing, I have an X5 2007 4.8, I recently changed the water pump and expansion tank and ever since I lost heater power,
the car start in the morning heat start coming slowly and very week (warm and never hot knowing temp is set to 28 C) from both center vents, when I start driving the driver start giving out cold air and the passenger vet becomes very less warm. sometimes cold as well.

I was told by the service manager of BMW that this could be due to an air pocket! any idea how to effectively bleed the system?
thanks
