M340i Aircon - Cool or Cold?

Quick poll please.

For a longish journey on a sunny day, with the vent temperature set to it's lowest, and climate set to Lo, do you get cold air out? I'm getting cool, not cold.

What are you trying to prove with vents at coldest and Lo setting? Is A/C function cutting out, due to freezing the evaporator? Not unknown on a lot of models.

What happens when you set the climate temperature a bit higher, at a regulated setting?

HighlandPetethanks - trying to get cool when it's hot so was trying it at it's coldest - good point about trying too hard.

So 25+ degrees on a short journey was enlightening (a little)
4 miles to the shops, get out - nice and cold
Leave Auxillary Ventilation on for 30 minutes
Return to warm car and aircon not cold.
Turn to Lo and cold vent temp - no change (as before)(getting uncomfortable)
Turn on max AC - aircon goes cold
Left it on max for 2 miles
Max off for final two miles - nice and fresh.
So maybe Max AC is colder than 'Lo + Cold...'??
Weekend trip to try next

You really have no idea what climate control is. Set it to 21, mid fan setting on Auto and leave it alone. Let the car regulate the temperature. The most I ever do it go down to 20 on a really hot day and 22 through Jan to Feb. Simples

Here in nor cal it was in 100's for a week or so about 3+ weeks ago. The AC did fine. Sure if car was out in the sun for while it would take a few mins to get cold. Many things affect the AC: of course outside temperature, has the car been sitting in the sun, has engine been off for a while, is vehicle moving, and probably more I can't think of right now. All this is assuming the AC is is working order.
Oh when it's quite hot out remember to hit the air recirculate button so you are cooling the air inside the car not the outside. Sorry if this is too basic for some,no offense meant

Have the climate control in my F30 set at 22.5 deg however in the G20 I need to set it at 20 deg to get the same effect. The climate control in the G20 doesn't seem to work as well for some reason.
