I posted this on the X5M forum but figure there are more 50i and M50i owners that might have this issue.

Ok this flat out sucks. 200 miles on the odometer and my X5M ac cuts out on me completely today. Was fine this morning but later on the ac just blows out hot air. Needless to say the car is barely drivable given the warmer temps we’ve been having in NY. Doesn’t matter what settings I change it’s still just blows hot air.

Spoke to two dealers and one thinks it could be the AC being over charged from the factory as he’s seen this on other 5 and X5s. Another dealer said they have two other X5s in for the same problem and they think the compressor needs to be swapped out.

After digging around it appears that all BMW V8's uses the same compressor from the 5 series all the way to the 8 series including the M variants. I've also seen others on here with the same issue and just wanted to know if there are others as well as inform you guys that if your AC isn't performing up to spec it maybe your AC compressor starting to go. One member was told by a dealer that BMW had a "bad batch" of compressors in recent build cars.

Beyond frustrated at this point!

Spooky. This is the 2nd or third separate thread on this issue by 2020 owners. This is NOT a common issue but it seems as if there was/is a manufacturing issue on 2020 models at a particular time of manufacturing. I wouldn't be surprised if there is a recall soon. It’s too coincidental here on the forum so there has to be a lot more out there. I am sorry this stuff can take some of the new car fun away but it can be fixed easily and it’s better that it’s a common issue rather than a one off electrical no one can fix.

Sorry to hear that. Better have it looked at soon. My AC has been working really well. Actually compared to my M550i where I had to set temp to 68, the X5M AC is very strong, cools the cabin down very quickly and I am setting the temp at 73 right now.

I doubt there would be a recall since it's not a safety problem and does not affect the driveability of the car. Most likely they will just issue a Technical Service Bulletin (TSB) stating to replace the faulty part under warranty.

[Frenetic]

Yeah, my AC is working, but it does seem weak (and yes I have the vent setting adjusted to max cool).

My Audi was comfortable at an Auto setting of 76. This car requires me to set it to 68 to feel the same...

Your right, I meant TSB by now. I generally set my auto climate to
73 all year long and leave it. The only thing I have to touch 3 times a year is the vent temp.

[VTENGR]

Mine seems to work OK. It will be more telling when we get into the real heat down here in ATL. Like Frenetic, I used to set my AC to 72/74, but for my X5, I have to be in the 68 range for it to feel like it's cooling.

[Alan l.]

I think with the bad compressors its either blowing cold air (fine) or its blowing hot air (busted). When its not working (my car) all it does it blow hot air out no matter the setting. Max AC, Auto, manual etc.... its just hot air 100%

I've seen others with M5's or M8s post how their AC would come and go but the end result was still needing a new compressor.

Mine works OK not great

[dds007]

2020 X5MC here. Mine is faulty.

Group lawsuit?

[Kief]

Doesn't X5 and AC issues go hand in hand?? Lol

I know hit or miss, but every generation of X5 I've owned has had issues (E70, F15/85). It either sucks at keeping the cabin consistently cool, or it breaks all together. My F15 had that notorious "band aid" smell (AC stopped working too) and dealer needed to tear apart my leather dash in order to fix. Huge PITA. My current G05 M50i is really no better at keeping the cabin consistently cool on Auto. It needs to be turn up to the MAX if I want it comfortable.

I'm a glutton for punishment, I guess. Still love our M50i

My '19 50i is nice and frosty and I live in South Texas.

[Frenetic]

Yeah, my S7 had a great AC that was intuitive and simple to use.

Setting it to a temperature had the desired effect as one would expect: 72 would mean the cabin would “feel” like 72 and it did it without having to set the blower fan speed to an audibly annoying level. Everything was automatic, as a true sense of the word “automatic.” It didn’t have any nonsensical sub menus or anything else that would or could influence that number.

72 felt like 72. Simple, end-of-story.

BMW has too many ways to skin a proverbial cat. Depending on what sub menus you have, setting the auto to 68 can “feel” the same as 74. And, it’s really weak generally speaking.

[mrjoed2]

Curious, do the V8 models use a different A/C system then the I6 models?

X2. I can’t stand how cold it is if I have the vent temps on max cold and the climate control below 69 degrees. Max cool feels like you can make ice. I like to be cool, not frozen out.

Is yours set to auto or is that manual? Do you get the same results in auto (assuming that is manual)?

Im getting very cold air in auto and manual mode.
Hope you all get yours fixed.

Yes, V8, day 1, AC worked. Day 2, no AC. Dealer is picking it up Monday.

No thanks for the lawsuit.

[Alan l.]

^^ yours was just built right? Mine was built around mid March.

last thing i want to deal with for the dealer to swap in another defective part. The chances of that are high if super recent build cars are still having the AC Compressor issues.

Took delivery of my X5 M50i last September. The AC compressor failed within a month. Dealer kept the car for a week trying to diagnose the problem and after consultation with BMW AG they replaced the compressor. That seemed to have solved the problem but the weather got cool shortly after so didn't get to use the AC much afterwards.

Now the weather is warm again I am noticing the AC struggles to turn on especially when the temperature is 70-80's outside. Very sporadic. Seems to be OK when it is very hot (90+ degrees).

Took my X5 in for service last week and asked the SA to look at the AC. Was told there were no faults recorded for the AC and the problem could not be replicated by the technician. SA said nothing more they could do.

I know the AC is still not functioning properly. The loaner I was put in last week was a X5 40i and the AC seemed to cool much more efficiently. Today I took out my temperature gun and measured the temperature at the vent while the car was running. Reading was consistently around 76 degrees when my AC temperature was set at 69. The temperature at the vent should be below 69 if the AC is functioning properly. I suspected the problem was with faulty temp sensors in the car but now I am not sure.

Good to know I am not the only owner experiencing problems with the AC. I hope BMW gets to the root of the issue and issues a service bulletin to fix the problem. Unacceptable to have a unreliable AC in a car of this price.

Did you check all the vents with your temp gun, or just the vents around the iDrive screen? The reason why I ask is because you could have your vents set to "warmer" for the stratified air feature BMW offers. I would make sure this setting is set to the coldest setting and retake the air temp and see if you come up with your same result.

[Alan l.]

checked it all....atleast 10x. No matter what setting the AC only blows warm/hot air out 100% of the time.

I was just told by my dealer that there is 400+ national back order for the AC Compressor and the earliest the system shows they can get one in is end of July! BMW is going to have a a lot of buy back on there hands....
