I experienced the "issue" where by watm air was coming from the floor vents today and it was when it out the car in eco pro from comfort.
upon investigation I noticed that eco pro had controlling a/c ticked which I thought I had unticked previously.
once unticked there was no issue.
so this eco pro presumably turning off the compressor to save fuel.

i bought several first year C and E models from Mercedes, never had annoying issues like this. same goes for my parents. they have first year models of the GLC300 and GLE400 coupe. no headaches whatsoever

in retrospect, i should have went back to Mercedes.

I have a friend with a 2017 MB E300. Came out of a CLS550 and is so sorry he went to the new E: The drop in power is one thing, but he has had electronic issues, but the most annoying thing is that the car has developed a lot of rattles at around 5000 miles. You just never know.

As you also figured out, "best" position is Auto with only 2 bars (or maybe one of the manual modes). Still, unacceptable that a car like this has issues with something that my dads Renault of 25 years ago already managed perfectly without a fuss :-(

Will bring my car to the dealer in two weeks time, but I do not expect any improvement after reading you last comment.

Will end up driving without my pants on :-)

In Belgium this may work, but in the US if caught we'd wind up on CNN.

Still waiting for BMW Germany to evaluate the data sent to them from my dealer. This is really getting frustrating.

You may want to report the problem on carcomplaints.com or similar sites. The speed at which BMW moves on this is directly proportional to the potential for bad publicity for a new model.

I haven't experienced any "issues", such as hot air coming from the floor, but for whatever reason I feel like the A/C in my 335 was much, much stronger. I find myself pretty regularly adjusting the vents, and yet never seem to be able to get it just where I want it. Air flow seems low, but if you bump the auto speed up a bit, the rear vents start screaming. Seems most of the air goes there.

Mine seems to always work exactly as expected, although I do get a few crackles on starting up when the sun's been on it for a while.

I remember my dealer telling me everything had been set up optimally prior delivery, so perhaps the problem lies somewhere in the config, and it may help to speak to your local guy.

Maybe that's a naïve assumption but can't imagine BMW have de-invented happily-working aircon.

[AP]

Drove in fairly warm temperatures yesterday (28C indicated) and the air con was just fine. no issues what so ever. Interior temp was set to 20.5C and fan speed I think was 4/5.



I do reiterate what I have written a few posts back , I'll quote here again just in case this might be the issue or one possible scenario.

"I experienced the "issue" where by warm air was coming from the floor vents today and it was when I put the car in eco pro from comfort.

I've tried every iteration of settings available. The fact remains that the passenger center stack vent has very little airflow. At Max A/C each vent is blowing well; however on the passenger side, the vent behind the iDrive screen and the rear passenger vent are blowing like mad. Every tech, service writer and passenger all agree that the flow is minimal at best. I'm hoping for a programming update that might fix the problem.

[steve090619]

my ac settings do not stay when switching keys. Now the Idrive screen freezes and I can't change sat radio channels. keeps rebooting. BMW has the car now, new I drive head unit. Wonder if this is going to fix my ac problems as well. I have a 530e loaner and the ac blows much harder than my 540xi.

That would not be the problem, at least on a 540 (not sure about for the 4 cylinder engine). Similar to the current 7 series, the 540 does not use a conventional A/C condenser. Instead, the condenser - like the intercooler - is water cooled. This is according to the technical training documentation.

FWIW; I had never noticed this before (.. in all 3 weeks of ownership), but I did when I was sitting in the car trying to figure out why the back-up camera had stopped working.. felt warm air on my feet. HVAC system was also making somewhat odd clicking noises, which I've not heard before (but to be fair, I'm usually driving so there's outside noise and road noise). Could be normal on the sounds.

What I observed:

1) Turning off auto, using manual fan control, the warm air to the floor stopped
2) It started again immediately once auto was enabled again
3) The clicking noises stopped if the HVAC system was completely off

BMW?s plan has succeeded. Now that it?s under 110° here in Vegas, I haven?t been as aware of the problem. Nothing has changed since my original posts, just the outside temp.

AC in my F15 X5 is crappy as well. Lots of complaints in our forums. Europeans just don’t understand what Americans expect out of AC and ventilated seats. Every time we’re in Europe we are sweating in cars and hotels. They just roll their eyes and laugh at us whiny Americans.

May have something to do with fuel economy, but I suspect AC is designed for European expectations.

The major German BMW forum is also complaining. 24 pages and over 50.000 views

Looks like in Europe they experience the same issues this summer. I read that it is in expected a major change (not soft/firmware) is expected in November and March 2018

Let's wait and see.

They must not have done much (or any) testing of this car in hot weather - it's pretty shocking that they didn't catch this problem before production.

Based on these German posts, there's hope that late 2018 model year cars and 2019 cars will have a proper A/C unit.

And I hope they incorporate their learnings into the G05 X5. Hope you all get some resolution.

Wonder if the new X3 is going to have issues...

[pharding]

They are not morons. The X3 will not have issues.

i wish i could believe that

[screamace]

It's warming up again (finally) and I revisited this thread hoping for clues/solutions. No avail

I now discovered that turning on re-circulation seems to help, however you have to press the button every time starting the car. I also set temp 5 degree lower than my X5 (67 rather than 72). Result? At least my face is not burning now...

[Dcinlv]

I decided that I'd try and get a jump on the inevitable Vegas heat. I reached out to my Service writer and Service manager in hopes of them having received word from Munich with a solution. My primary complaint was extremely low flow from the entire right side of the center stack and the need to endlessly experiment with the HVAC settings.
I'm pleased to report that after a software update and removal of some "excessive foam" from the right supply plenum the A/C is flowing like my 2017 X5 and the 15 previous 7 series I've owned. Very happy to hit summer head on with greater than 50% of cabin airflow restored.
