As I keep saying on this thread user error/expectation.

Can’t miraculously cool 110 degrees or hotter air in a big suv. The hot air has to be replaced. I had same problems with ford expeditions but didn’t have the ASS and I also had rear windows that would partially open.

Air out the car or pre condition. Don’t let it go into ASS. Moving helps cool the condenser better than sitting idle. Last week 95 plus and 110 heat index. My car sits outside. I rolled the 4windows down and could feel the heat blowing from the back toawards me when I forgot to pre condition.

I don’t think think the big moon roof helps either. I don’t even use it

Thanks for the link, no I will take it to service in a few weeks,
I think most of my frustrations are that I don’t feel the air on my face. Today I drove it and turned off all the second row vents and put it on max ac and the top fan speed and I feel cool air with my hand at the vent, (not as cold as other cars), but I can’t feel the air blowing in my face, I spend lots of time trying to aim these vents and I eventually give up. Other cars I ride in I feel air blowing on me even on the low setting. The max fan speed is just not “max”. I really think my g05 had 7-8 fan speed levels on manual.

The center vents definitely suck and have poor airflow. Will we ever get to a point where a design is done? I thought air vents you can see with a lever was a final design, for ever. Guess not. Maybe we need magneto aero dynamic variable air events. I bet terrance howard has a patent on them. 😆 🤣

[tewai]

Side vents are damn joke, I have to keep the fan speed on vacuum cleaner level so it blows atleast something and my arm doesn't get toasted since BMW didn't other to manufacture anything simmilar to Audi's or MB glass with sun protection.

Shame I cant do any tint on windshield in Europe.

I know the car is big but guess what, GLS and Q7 is the same size and they have no problem with AC.

GLS is bigger and Q7 is smaller but I get what you’re saying!

That AC in my X7 M60 is so anemic!
Not even close to my Range Rover and Escalade!

I was suprised how quickly putting the car on sports mode changes the air temp. I suggest if you want cooler air faster, keep it in sports mode for the first 10-20mins.

Great analysis here.. my experience and hypothesis generally lines up with your findings, just without the data. BMW designed this AC/climate control to an efficient standard first. I think the problem is that BMW looked at what you analyzed here and said, that looks good. To your point the typical home HVAC system is targeting ~20 differential, with the idea that its on constantly so the temp never gets out of hand. During a 3hr drive in 95 degree weather once the cabin was at temp i could actually feel when the climate control periodically pulled in outside air as the vent air would briefly feel warmer and more humid (i have my recirc on auto)

BMW with this AC, (and with some idrive UX stuff in general) seems to be missing the perception is reality problem. If you look across the board most automotive ACs are brutally overpowered for the purpose of delivering that instant cold, they are designed for the short trip and instantly cooling a super hot interior as a priority. While not the most efficient, it is the general market expectation for an automotive AC. Example: with my raptor folks actually recommended not to run the ac full blast for too long as it can easily freeze the compressor.

[kilowatt88]

2025 X7 40i just got it.
Also noticed the weak AC problem.

Also, ventilated seats appear to be on the weaker side with air not being very cold especially on the back. The system also seems much more noisy. Idk if this defective seat, or its normal.
Had Q7 before it, seat ventilation was rock solid and very quiet.

[Chi6488]

I think the problem with the AC is that BMW did not ventilate the condenser properly.

If the vehicle is sitting still the air is warmer than when moving. If the vehicle is moving the air blows cold as any car.

I find that if I do not pre condition and airing car out when I first get in the air will blow warm waiting at light. Once I move than all is good.

I tried to look at the condenser fan but it was all covered up. Will check if my wife’s MB radiator/condenser area is all covered up or not.

That particular condition has a lot to do with the auto stop start, bmw did not move the compressor to the 48v mild hybrid system so when the car stops and the engine shuts off the compressor is relying on the residual refrigerant temp.

considering some of what has been noted about the compressor/ac system being undersized for a typical automotive application that refrigerant heats relatively quickly especially with a still warm cabin (I think this is yet another experience design flaw, cabin should be much closer to target temp on ac before the auto stop start kicks in)

I don’t let my ASS kick in. I manual lwtnoff brake and brake again to keep motor running but at dead stop the condenser is not cooled enough to cool the refrigerant

[RJC-1]

When we tested the two new X7's we made sure the auto stop/start restarted when stopped,by immediately taking foot off the brake, but it made no difference whatsoever in AC cooling. With the massive heatwave affecting most of the US BMW better get their $hit together and figure out what exactly is going on here and why some are working well and others not. As I mentioned previously in my thread, some new 24 RR's are having ac issues as well and my best guess is in addition to sharing the BMW's V8's, they share AC components as well. My bet it's faulty compressors or faulty electronics telling the compressor when/when not to kick in/stay on, or something to that effect.

Again, check the temp coming directly out of the vents and you'll have your answer...the vehicle's color, size etc. does not matter when doing so as the thermometer should be placed inside the main vent. If the temp is above spec there's an issue, if it's not then there isn't. https://www.acdiagnosis.com/post/pro...enheit%20range

All I know is the two '24's we tested ac's were anemic at best and both us and the SA tried every possible combo to no avail. The MHEV MB GLS450 as an example is not having this issue, especially at this level (~44%) complaining.

It's a shame BMW can't get its act together, especially as climate change makes it hotter every year!

When we picked up our MY23 GLS450 last year, there was a shortage and most dealers in our area were commanding $10-20k ADM (I only paid MSRP)! We were unaware of any AC issues w/the X7 but have made many road trips where we were thankful returning to a cool car was always an option!

Also, the AC compressor keeps going w/refrigerant even when Auto stop of the engine is engaged!

Sir, BMW’s ventilated seats do ABSOLUTELY NOTHING but noise. Period.

[tatoweb]

The problem on my 24 is not the temperature coming out of the system, but the amount of air which is very poor in the middle vents and a total embarrassment on the side vents. Yes, I have 5 zone A/C.

And don’t tell me to precondition because let’s say you leave home early morning with the A/C temp set at 74, LOW fan speed (even though it’s in AUTO, you still have to adjust speed sometimes. Totally ridiculous), you park at your destination and leave. Then, it’s 3pm, 100F outside and 130F-140F inside the vehicle so you “precondition” and the stupid A/C turns on your last setting which was 74, LOW and not on its coldest temperature and highest fan speed.

Then I said. Ok, paid $100,000 for this POS but I should remember to touch “MAX A/C” before turning off the vehicle at my destination so it preconditions on MAX A/C. Turns out the stupid A/C will not precondition on “MAX A/C”, but again on the setting you had prior to hitting “MAX A/C”.

So, the only way to get SOME precondition is to remember to set LOW TEMP and VERY HIGH fan speed before every single time you turn off your car which is NOT as powerful as setting “MAX A/C”.

The dumbest A/C system, ventilated seats do NOTHING but noise, no unlocking by touching rear door handles, car honking like crazy when you step out of it with your phone, no way to turn off ASS so it does not reduce the A/C flow.

I regret buying this POS.

Im gonna watch for this, haven’t noticed to date other than, as I noted, when the motor goes ASS off.

lol you should have only paid 50k and got a palisade. So embarrassing when I drove my parent’s cheaper palisade recently and it cooled me so much better on a low setting! My x7 never goes to a low fan setting like theirs does on automatic and I never feel air on my forehead ever on my x7…. Definitely felt the air in their car on the cheaper palisade… Also I just love getting heckled asking why there isn’t ventilation and messaging seats in the second row! (Not sure the palisade has messaging at all) I mean for real, I wouldn’t want to drive my moms palisade, but for real, why did she pay half the price and have better ac!. Embarrassing

[omnid00d]

I just did a roundtrip from SF Bay Area to San Diego, driving I-5 through Central Valley which was 100+F for several hours. AC is only merely adequate but definitely not up to expectations. The roof of the cabin still feels warm, it's barely able to keep up fighting the heat coming into the car. BMW either knew this and made a decision or didn't and fucked this up. My money is on they made a decision, for reasons only they know.

I'm taking the car in later on Friday to get an oil change (I did it every 5k miles) and will ask to get the AC system looked at. If anything, just to have it documented as a customer inquiry/complaint.

Thank goodness I don't normally drive in that kind of heat but I used to live in Austin, TX and I Would be pretty livid like many in this group.

If that doesn't do the trick, it could be something like low refrigerant, a clogged cabin air filter, or a sensor issue. Since your car is still new, it’s a good idea to have the dealership check it out under warranty to make sure everything’s working as it should be.

Trust me man, it's not the settings. Look at the other AC thread. The issue is not how cold the AC gets (low refrigerant), it is the lack of airflow that these AC vents produce. This car's AC just flat out sucks compared to other cars in the class. To produce even the smallest amount of airflow, the fans have to run at max noise speed and you still don't get a lot of air. All you get is a noisy cabin where you literally have to yell for the person in the passenger seat to hear you.

It's funny because I just had the X7 in for service and the service advisor in a video he sent me said "man you can really hear the fans running now, nice and loud". Dude, they are nice and loud but they still don't blow any air. So now I have the worst of both worlds. Thanks guy.

That's OK. When BMW Executive Customer Care responds to me with the same nonsense, I sometimes feel like I am responding to a bot there as well. Sort of used to it by now.
