The only annoyance i have with my C40 after 12 months ownership is the pathetic operation of the climate control. The Auto function isnt truly auto - yes it directs air across the vents as it sees fit, but the air speed is still determined by the fan speed setting.

Example - car sat in office car park all day yesterday, outside temp 27'c. Climate set to air con on, 18'C, Auto and fan speed 2. in order to cool the car down in less than 20 minutes the fan needs to be manually adjusted . Yes i could leave the fan speed set to 5, and the fan speed will go up n down as needed; but i dont necessarily want to be blasted with fan speed 5 either

This really is poor for a £50k+ vehicle - every car i've had since 1999 has had a full auto climate control

Set the temperature to LO and it overrides your fan setting

Not on mine it doesnt - -i've had it set to lo for days with fan speed 1 selected. You could cook your dinner before the cabin cools down ;)

I have the fan speed set to 3 and everything works fine for me. Guess it's your choice to set to 1 and suffer the consequences, but seriously can you really complain when you set such constraints upon the system?

Owner’s manual recommends to set fan speed to 2. I drove with fan set to 1 and the air con couldn’t cool the car. After setting the fan to 2 air con functioned flawlessly.

yes its a choice, thats not my gripe

Just enable full auto climate control, not auto air distribution, manual restriction of fan speed control. Is it too much to ask when cars a third of the price offer it ?

OK, I understand. Both of my XC40s automatically control the fan speed. The manual setting serves to limit the maximum fan speed, it can be rather noisy flat out. Defrost, Lo and Max override the manually set limit.
Perhaps yours has an issue?

Ah, that it limits the max speed is interesting. I knew mine adjusted fan speed on auto (as it should of course) but not about the limit. I think mine is 3 but, being in the UK I might increase it as max speed, although noisy, is unlikely to be much needed!

And if you read JFDIT’s response you’ll see why setting it at 1 is the whole problem.

GRAF, from what I can tell the number you manually set the fan speed to sets an Upper and Lower speed range for normal operation, within which the system automatically adjusts depending upon need. Setting the heating to Lo or Hi overrides this as does a double press on the Front Screen heater.
I too find 3 to be the optimal setting for ventilation and fan noise.
