Hi guys,
when I let my 2005 X5 N62 idle, once the engine temperature is at 12 o'clock and heat all the way up, if I have the fan blowing full blast I get cool/luke warm temperature. If I keep the fan at med or just a bit more, I get very hot air. (BTW my aux. water pump is working, + new thermostat.) (If I rev the engine to 1500 rpm or higher, I get hot air) Does anybody know what I should be doing/changing to fix this?
Thanks for your help.
