I think there might be only software problem?

The G30 has new thing, closeable grill. I guess when u start an engine its closed so if you have car on open air with closed grill its hot. So maybe is there any chance for correction of this..???

its only my tip. I have no clue whats happening + I still dont have my car yet.
Actually we got 34 Celsius so it would be nice for testing. Hope its going to be in aprox one month +- like now and then I will test it :-)

[Laki021]

Nothing to test, it works just fine...

Update on day 2 in the shop...

My service advisor called me to give me an update. I have to say that he is very nice and so far being very transparent on the issue with my car.

I will try to recall what he told me, but I am not a mechanic so please forgive I mistate anything.

They have discovered that the fan is not getting the required voltage. The engine management system is reading the fact that the fan is not getting enough voltage as overheating problem. To prevent the engine from overheating the system cuts power to the AC, which is why I was seeing it cut off on acceleration and putting demand on the engine.

They are not sure where the voltage loss is coming from. There is no other indication of an electrical fault. BMW has told them to replace the fan itself and its on order. Should be here on Monday and they will install and re test.

I know not all of the AC complaints are the same as mine, but I beieve the OP was having a similar experience. Maybe this can assist him with a possible diagnosis.

At any rate, will follow up once I see how the fan transplant goes.

Hmm engine overheating.. again that may be because of closed grills in wrong time? Or some big engine problem 🙈

Does it happen in all G30 or just some engines?

With "the fan" you mean the fan that is cooling the coolant of the engine?

So basically, your engine cooling is failing and the "smart" car is trying to help cool down the engine by disabling the AC. So the problem is NOT with the AC, but with engine cooling (which is worse). :-(

I spoke with service again to gain a better understanding of the issue.

Yes, I mean the fan that cools the radiator is the fan they think is experiencing a voltage issue.

I say think, because they cannot confirm at this point a voltage issue in the car. However the car "thinks" it has a voltage issue and is drawing power away from the AC. They are not sure if this will solve the issue, but perhaps when they change the fan the car will "read" it correctly, or if there is an actual voltage fluctuation the new fan will not have it.

Let me be clear, the engine has never overheated or displayed any indication that is getting hotter than normal operation temps.

I mentioned there was another car with the exact same issue in the shop. Its a 540i. BMW is having them do the exact same fan swap on both, however I guess mine is the guinea pig to see if it works. If it does then, then they will repair the 540i the same way.

Base on other things I have noticed with the car, I just feel there is something off with it.. maybe software or electric. While I hope that this does fix my issue, I just am not too confident it will.

Just to put the air-con argument to bed (hopefully!) took delivery of 540i xdrive on 21st June. Temperatures here in UK were 33 celsius/ 91 Fahrenheit - the aircon on full was so cold it was painful! As an aside; going from dashboard at incredible heat from being in the sun to maximum 'chill' and back again did not result in any noises or cracking sounds from the dash - possibly a few gremlins sorted out on the production line?

Hopefully yes, good to see but as an old English saying don't count the chickens before they hatch to adopt this word don't say it doesn't crack before sun scalds . Mine is late May or June production I will let you know if it makes cracking noises or poor A/C performance

Thank you for the updates, I am having the same issues with my car but my service dept doesn't have any loaner cars so they don't want to put my car in service since they don't know what is wrong. Its so hot this whole week has been 115+ outside and my car just doesnt cool off even with tinted windows.

Just to put this in perspective, not trying to boast or something like that. My G30 (Feb production) doesn't have the problem of AC or dashboard cracking noise

B47 Engine 520d M Sport Alpine White with Cognac interior with technology and Visibility Packages. The other added options, are apple CarPlay, remote services, reversing camera, heated steering wheel and automatic folding mirror.

Don't make my mistakes, my other options minus CarPlay would have been the same price as a comfort package. I am still seething.

Ooooh. Can someone confirm a part number difference so that we can get a change for our poor cars that still crackle.

I feel your pain - it was brutal in Phoenix this past week too.

Here is my Monday update:

BMW decided not to change the fan. They stopped the service center from installing it after it was delivered. It appears the consensus is that replacing a part that does not seem to be defective is probably not going to resolve the issue.

They want to keep my car indefinitely, while they work the issue. I guess I am okay with this, since driving it around would suck in this heat. I have a X1 as a loner.

About 2 weeks after I bought the car, the gear shift had to be replaced as it would not stay or even engage Sport mode. They had to order that part as well. There are other electrical bugs that are harder to nail down as well...home link not working 100% of the time, seat memory to name a few.

Yes, I ruled out operator error on all of the above. After the gear shift was replaced, I could have lived with the small annoyances. The AC however is not something I could live with. I like the car, but at this point I am pretty frustrated. My first and most likely last BMW.

I am glad most of you are not dealing with this issue.

Yeah I just don't understand how they can't figure out whats wrong with it. My Bmw dealer told me today another 540 is actually there as well. But still no loaners available. Kind of crazy

My dealership offers Enterprise cars as a back up to their loaner fleet, maybe this is an option for you?

My service rep told me yesterday they are hearing about more cars with the issue, all in "hot" areas. AZ is a testing zone for a lot of manufactures, probably due to the heat. I have seen Audi and Porsche test mules on the road and I think Nissan and Ford have proving grounds out here too. My point is I would wonder why BMW would not test here. Maybe they did, maybe this is just an anomaly in a hand full of cars in very hot areas.

I am really surprised that this is occurring at the rate it is. I am even more surprised at the fact that they have no answer.

The air con in mine never changes speed. In auto climate it's always blowing on the second lowest fan speed. Doesn't matter if it's boiling hot or freezing cold. I have to press the MAX AC button to get the blowers to actually do anything meaningful.

[AP]

isnt it like the f10 where you need to set the intensity (or probably max intensity) for each side of the car?
this governs the maximum fan speed it will use so if you set it to say 3or 4 or even 5 leaving it in auto still and I am sure that will sort it for you.
