Is it just me or is this happening to any of you guys?
I have a 2020 M8 with 800 miles and my AC is freezing cold then goes warm for about 3 minutes and then cold again. The climate control is unusable. My dealer tells me he currently has 3 all under 1000 miles doing the same thing and they have no idea how to fix it.

Check out this post from Wolfman64 as it has the best info to date which ultimately is a software fix. It makes complete sense as the issue is non-existent for M850i's (N63) or the 840i's (B58) yet the condenser, compressor, etc. are likely universal across the 8-series.

According to our SA, there is an issue with the 8 series with S63 engine where either the evaporator or condenser freezes up and then the AC stops cooling even though equipment is working and Compressor is good.
According to him, there is a software fix coming to address this.

The text reads a bit different but here it is...

His car still isn't working though even with the update according to his post from earlier. https://www.bimmerpost.com/forums/sh...php?p=26391660

Just for clarity there was no software update done based on Wolfman64's original post with info from his SA. The second post I can only assume means that the "Max AC" band-aid in the notes from the SA does not really work consistently.

The irony being that on my wife's X5 which I had the AC checked during the first summer of ownership requires the "Max AC" band-aid when the temperatures here in Phoenix are over 100 degrees. The system itself is operating within specs and it is not an issue of going from cold to warm, etc. but rather the cold temperature just sucks at 100 degrees plus to cool down the cabin. With Max AC it just sets the temp to 60, auto engages re-circulation and puts the fans on high which helps until the cabin is cooled down and then we can disengage it.

Thankfully, the AC is ice cold (similar to several prior Lexus) on my 2020 M850i. My CA told me that they've fixed the AC issues on the current gen of X5s (starting in 2019) but there is no way I'm buying a new one considering the 2017 is fully paid for and the Max AC band-aid does the job.

They did a software update as well to 3/2020.58 from last years version. I am inquiring as to why we are not getting a newer one as Limey has (5/2020).
Don’t have any hope another update will help unless it’s a June or July one.

My SA specifically pointed to this being a S63 car issue only. No 840/850’s are impacted...

So somehow after latest software update my AC works too well now. It handled 98 degrees without any issues.

Thanks for the clarification as I was going by the SAs notes indicating a future software update. The 03/2020 release has been somewhat of a shit show but hopefully the .58 release is stable. So far only Limey has the 05/2020 as far as I know. A conspiracy theory would be that it has a super secret enhancement for a M8C GC so hence he's the only one with it on the forums.

My M8 with 750 miles is now receiving a new compressor, condenser (on backorder) and evaporator. Sure hope this works

I took delivery of my brand new M8 Competition Convertible a few hours ago and literally as I drove it off the showroom floor, the a/c failed.

Blowing high but hot air.

Dealership says they are having tons of similar issues with a/c in all M8s and it will take several weeks for backordered parts to arrive to fix.

Parts needed seem to be new condenser and sensing units, whatever that means.

Bummer.

This, again, is outrageous. BMW and its dealers are selling and putting on the road cars that they KNOW are defective.

Wow that's terrible to hear. Do you plan on keeping the car? Or will they at least defer payments for you if you do plan on keeping it?

Not a good sign that BMW still is letting people buy these cars only to have issues within little time of ownership, doesn't reflect well on BMW and won't help their customers happy and hopefully loyal.

My salesman said he would talk to bmw about covering first payment. We'll see if that indeed happens.

BMW will blame it all on covid19

Same problems in 2020 M550

Someone in the 5-series forum pointed me to your thread. I am having the same exact AC issues with my 2020 M550. The dealer has been trying to solve this for 5 days now and is clueless about what to do. I have told them if they can't fix it, I expect BMW to buyback the car. I get colder air blowing from the AC in my 911 C4S with the top down versus the M550 with all windows up and the AC set on 62

The a/c units (the entire system) in many of the new vehicles are 'contaminated' from the factory. Total replacement needed.

Your dealer should have received several service bulletins from corporate about this.

Impacting several model types.

Parts will take a few weeks up to a month to arrive for them to receive and then replace.

AC Freezing then warm

My update after 2 weeks is that the dealer wants to replace the entire AC. Then the dealer notifies me today that it'll take an additional 2 weeks for parts and another week to perform the work. This is a crappy car and I'm selling it regardless of the loss.

You're going to take nearly a 40% loss (sticker - what ever discounts you got). Unless you bought it way below sticker and find a private buyer to pay close to sticker; you're almost guaranteed a 30% loss minimum.

I was prepared to take that same loss, but my wife talked me out of it. And now we have the M850i on cinder blocks in the garage.

Would be nice to get a copy of the bulletin for those of us yet to take delivery.

May come in handy to negotiate a delay in delivery till fixed.
