A/C Stopped Working - X6, M50i (N63/S63 A/C Issues)
I know there are several threads out here, across multiple boards as this is being seen across X5M, X6M, M850i and X5/X6 M50i’s. (I would guess X7, M50i's as well, but I haven't seen a thread with one...)
Here’s are the threads I’ve read (and there are links to others in some of these…): - A/C randomly “stop cooling” intermittently for a few seconds? - Nightmare story of my M50 finally showing up. Recommendations? - Annoying Issue with A/C not cooling consistently I’ve felt that I've noticed the A/C not working quite right a number of times, but have blamed it on me reading the threads out here where people were reporting the issue and I was "looking" for the problem. However, today was much different!! Here's my quick rundown: - X6, M50i. Production date was 3/24/20 (squeezed in right before the plant shutdown in Spartanburg). Delivery date was 3/28/20 - I'm at approximately 2,300 miles on the odometer - Original iDrive SW was 11/2019.55. It was upgraded to 03/2020.58 on 6/19/20 while BMW Tech was troubleshooting an issue I was having with the driver's side SurroundView camera - As noted above, I'd felt like there were a few times where I might have been seeing some intermittent issues with the A/C, but I blamed it on "knowing too much" from reading this forum! Also, it hasn't been that hot in the Midwest until the past few weeks... - Today, I went out to grab lunch. A/C worked perfectly. Returned home, vehicle sat for a few hours and I ran out for a couple of errands. First stop was a couple of miles away. A/C worked fine. Stop was 45 minutes and vehicle was turned off. I fired it up to head to my second stop and I had no A/C for the entire trip of about 20 minutes. I played with all of the settings, turned AC on/off, tried ‘Max AC’, etc. Nothing changed it blowing just hot air out of all vents. - I took it out late this evening after sitting for a few hours, just to check again before shooting an email off to my local dealer SA and still nothing. It just blows hot air… I’ll update as I know more…I have read the threads across this and the other forums and repeatedly read where there is apparently a TSB/SIB published, but couldn’t find anyone that listed the # or details. Anyone have it? While it seems like there’s some thinking that for many, the failed compressor has shown up early, mine might be a case where it took awhile. (But, given it was pretty cold here in April and much of May, the A/C just started getting a workout a few hundred miles ago…) Also, some thought that there are a couple of problems, I’d conjecture that it’s quite possible that continued intermittent problems might lead to the compressor failures. At least, it feels like that might be the case for me. However, I’ve not had it looked at yet. Hopefully, my dealer can get it in quickly…) Again, I'll update as I get more detail...While I know that forums like this always make it seem like everyone is having the problem, it's usually just a few. However, it does seem like quite a few N63/S63 owners are seeing A/C compressor issues... Last edited by kkratochvil; 06-30-2020 at 11:59 PM.. Reason: Adding additional link to another forum post. |

Sorry to hear. Sounds like your is gone too. My X5M was built the same week as yours. Once the compressor went out it never came back. It blows nothing but warm air no matter what setting its on.
I really hope that BMW got under this issue and figured out if ithis was a design problem with the compressor or did the vendor they used screwed up. I would be pissed if they replaced my faulty AC compressor just with another one that fails within a few weeks/months.

I was thinking the same thing as I read through the threads last night...Why do we think a new compressor is going to resolve the issue if they're still rolling vehicles off the line with failing compressors? |

Just tell them there should be a service bulletin out from BMW so they can look it up. If not tell them to look up if they can obtain a AC compressor and they should see how many are on back order in the US and Germany then back track to the bulletin.
When i brought my car in the tech took less than 30mins to diagnosis and do all of his checks before giving me back the car.

Also wanted to add the shop foreman said BMW recommended changing the AC compressor as well as some other parts because metal shavings from the failed compressor could have made its way to those parts.

Honestly, I think replacing the compressor and the coil unit and piping is becoming pretty regular with A/C system replacement these days. I had to replace the unit on an old 2006 Honda Pilot recently and they've gone to it even with those units. Essentially, it's become a "closed system" and you replace all of it, due to the exact reasons you posted, where there's metal that can get in the coils and they've become so fine that there is no such thing as flushing them, etc. |

So add me to the list... Built 3/2020... x5 m50i. First time it did it was with 45 miles on. Second time on the way back from Austin in 95 degree weather with about 500 miles. It did not work for about 1 hour and then all of a sudden started working and worked all the way back. Now with 1100 miles on its consistently not working... kinda crazy that this is happening on these cars!

Sorry to year you had the same problem Buddym850icoupe.
I totally agree this shouldn't be happening for any of us. For BMW, it seems like a significant problem, as it's happening predominantly on $85K+ vehicles, with it happening on the V8's...So, they really should be stepping up. So, I did get mine in to my dealer on 7/2. Quick synopsis is a failed compressor. Compressor is on backorder. As of Thursday, 7/2, there wasn't a compressor available in the US. Germany parts center was expecting a shipment to arrive today (7/5). My dealer is expecting to have one in 7/10 business days. I attached a snapshot of the diagnosis below...I'm not sure they actually connected it to the TSB/SIB that @Alan I mentioned. I may push that a little further with the Service Manager this week. Just want to make sure they fix things correctly. I did have a chance to follow-up with the Service Manager of my dealer's sister store (Mercedes, across the parking lot), who I know quite well, as I asked him: "How do I politely push/confirm that the next compressor isn't going to fail as well?". He checked with the BMW Parts Manager and as it turns out, the new compressor is a new part #. We can probably debate whether a new part # means that it's a "bad batch" or of it was in-fact a bad design or supplier. My thought is that the new part # means it's a flawed design/supplier, rather than a "bad batch" and they're now replacing with a different compressor. I'll call BMWNA Customer Relations this week to complain about the quality of the vehicle...trying to push them to do something. (This is actually my 3rd issue with my G06. The first 2 were very small...) Given they know it's a part that is failing repeatedly, they've likely gone to a new supplier/design, they should have had more parts pre-positioned in the US (and elsewhere...). They're obviously going to keep failing... |

Update: I reached out to my dealership this morning and the new compressor arrived this morning. So, it was around 11 calendar days from ordering to get the part in.
Take my X6 in tomorrow to have the compressor replaced...I'm still a little leary that they're going to find they need to replace the compressor too, as that's what others have reported, but will wait and see. |

Mine just went in this morning for the AC compressor work. Trying to get my tech to confirm if the new compressor is indeed a new part number.

I had this exact same issue with my X5 which was a 2019 MY. It happened to me right away. The same thing i noticed was that it worked ok almost all of the time but if i shut down the car for a short time and then got back in. For example at a gas station it would not work the entire trip from there. Get back in after letting the car sit for 1+ hours and the AC was back. I can not recall if they finally changed a part but with software updates and a few since that. I am currently on 03/2020.58 and haven't had this issue re-appear. I did however have a green oily flid leak under the car twice and finally found a small crack in the lower radiator and that was changed about a month ago.

Update: I had my X6 in today for the compressor replacement. I attached a picture of the results. They only replaced the compressor and a couple of seals. It's a fairly short drive home, but A/C worked well. Ahhhh...
The part # of the new A/C compressor is: 64-52-6-822-848. In looking at GetBMWParts.com (A/C Compressor), it looks like the old compressor part # was: 64-52-9-380-568. Time will tell if they should have replaced the condenser as well, as they are doing in some similar situations... So presumably, if you're one of the many with this situation on your N63/S63 engine, you'd want to be sure that you're getting the new part #. Also, I called BMW NA Customer Relations yesterday to lodge a formal complaint of their handling of the A/C situation. This was the third time (over a couple of years now...) that I'd called Customer Relations and it was by far the most apologetic and positive call I've had with them...The first person, who typically walks you through the ringer in terms of basically saying (Are you sure you have a legitimate problem?), did little more than take down my information and asked me what sort of reparation I thought would be fair. I threw them a couple of ideas (after thinking about it and stammering for a bit, so if your call BMW NA, be sure to know what you think you'd ask for before calling!) and they noted those and I got a call from a manager about 4 hours later. That person asked me a few more confirming questions, including verifying the reparation ideas I'd suggested and said I'd hear more in 5 days. As compared to my previous calls, I think I have a decent chance of getting something... Last edited by kkratochvil; 07-14-2020 at 09:09 PM.. Reason: Added some additional detail. |

Glad you got the car back but that's the same part number that is currently installed on our cars now from what I gathered. The other number you listed is a old one but was replaced several years ago.
https://www.realoem.com/bmw/enUS/par...4-52-9-380-568 I hope my car will be done tomorrow and I'll get more info from the tech then.

I look forward to what you can uncover. I know it's also one of the things that I asked the BMW NA Customer Relations folks to answer...the persons initial answer was: "Well, any further issues would be covered under warranty." My response was that I understand and appreciate that, but I'm looking to understand how they can demonstrate that I'm not waiting to be inconvenienced again. |
