Fresh air ,help needed.
 

Thanks for reading this and any help would be great.
I can't find a way of bringing fresh air into the cabin ,coming from the e53 that had the tempering dial I am struggling to find a solution.
There are some days when I don't want to run the air con ,it's not that I'm trying to be cheap but I like fresh air. If it 20C outside the air coming out of the vents feels like it's super heated . I know this car is much hotter it doesn't seem to have the roof liner insulation as good as the previous model and the heat from the black headliner if awful. But after driving for a few minutes in not hot weather (about 70 F ). It feels like a fan oven blasting hot air at me. I've resorted to driving with the vents closed so I can enjoy fool fresh air with the windows open and not have the oven blasting me in the face. I checked all the office settings and from what I can tell it should be sending cool air at me but alas no.

Any ideas I have used the Foxwell but no codes for HVAC system so I am at you mercy. Pleased help.

I'm not sure if I am understanding you correctly or not, but if I am..

You can adjust the temperature of the vent outputs in the E70 as well, but you have to go into the climate menu under vehicle settings in iDrive, there is no 'trim wheel' like the E53 had...

Ok I'll try and explain better outside temp is 20c so driving with no air con on just the fan at low speed after a few minutes of driving say 10 or 15 minutes the air coming out of the vents is hot way hotter than the outside temperature. I can only assume as the e70 has no bonnet vents that all cabin air is drawn through the engine compartment therefore naturally hotter than the ambient temperature. Is this not the case? Is the vehicle designed to be driven with the air con on all the time? Where does it draw air from? On many occasions I drive with passenger and driver windows open but the vents closed as with them open they blow hot air. The air con is left at 20C year round. At 20 outside it should be drawing ambient air not heating it. Does that make sense?

YES! I am having this exact same problem with our X5 right now. Trying to explain this to our BMW service advisor.

Our AC refrigerant was low to start with, 100grams in system that should hold 700. So we are starting there.

It still does not explain how, on a cold day (45 degrees F or 7 degrees C) we have both driver and passenger HVAC temps set to 60, yet the air coming out is super hot. It's as if we set the temp to 90 on both sides. This is with AC off.

It does not make sense that one has to run AC in the car year round, especially in New England.

How is your heater control valve? You will get constant hot air out of the vents if the valves have failed (the rubber inside them deteriorates and sticks the valve open). Very common failure point.

You mean part Part 64116910544? I replaced it with a new, genuine BMW valve. No change in heat output.

I did mean that one yes. Bummer.

I wonder if the foam has failed around the fresh air boxes and you are getting engine bay heat in that way.

Funny you mention that; the rubber/plastic piece fell apart into a million little brittle pieces when I first got the car here from California. No doubt the heat and age being from CA degraded it quickly. I took it off and tossed it. Thought nothing of it.

The dealer just told me the "engine partition wall is damaged and missing. This allows hot engine air to be drawn directly into the fresh air intake for the climate control."

Kind of looks like this piece:

Did you solve this issue? having similar behavior (Air comes HOT always, regardless of being quite cold outside...), already change settings in iDrive, Checked A/C refrigerant but no change
