Auto fan speed

This is interesting, so when adjust the temp using the knob the fan speed never changes to help the car achieve the auto temp I am asking for. So I manually have to make the blower go faster.

Normal ?

Cause in my 335 the fan speed always changes when I up the heat on auto.

I figured it out (maybe). So I noticed that if it's in Auto that it will only go to the maximum intensity indicated under the fan button. I read in the manual that the auto function maintains the intensity you desire. So when I set it to max intensity on auto, I noticed the fan speed varies and increases like we expect when you lower the temperature for maximum cooling. When intensity is set low, it won't pass that intensity. Let me know if anyone else has the same results.

My fan speed does not move when I adjust the temp.
Gonna have the dealer check it out since I am going for a stupid oil change as need by the dumb computer - now they gonna drain my nice Redline oil and put in crappy BMW LL, even though I just did it less then 1 month ago.
