I'm assuming everyone is changing the stupidly well hidden option in the climate control menu that controls the mixing of the middle/upper vents? It's the digital version of the blue/red wheel in the older cars like the E46/E39...
Stock setting is in the middle which makes the air coming out warmer than it should be.

I live in a tropical State and the A/C and vented seats can barely keep up on 100 degree days. It's about 70% as cold/strong as my E46 M3 and about half as cold/strong as our GLK. I test drove several G30's before purchase and the A/C operated the same in all.

Many thanks Qsilver7 & TrialNerror - I’ll ensure the controls are set to cold - I wasn’t in the backseat, just put my arm back so couldn’t see the dials. Thanks again

That only seems like an option for cars with 4-zone clima...

Just brought my 17 540ito the dealer for this exact complaint and they started with the software update. It seems like it is acting better. Like others said not 100% but better.
If anyone care the info of my invoice is below. CUSTOMER STATES THAT THE AIR IS COLD WHEN USING THE A/C BUT THERE NO VOLUME COMING OUT OF THE CENTER VENTS. CHECK AND ADVISE CAUSE: SOFTWARE 6100730 PROGRAMMING/ENCODING CONTROL UNIT (S) 50388 W FC: 6400315xxx PART# : COUNT: CLAIM TYPE: AUTH CODE: Last edited by Supacat; 08-22-2020 at 11:35 PM.. |

If I'm one of the "guys" you're referring to...then no, I'm not saying you can't override the setting on the rear AC control if you have the 4 zone climate option. But if you don't have the ALL or SYNC button initiated...then warm air could be coming from the rear vent if a rear passenger turned the dial into the red area.

I'm in the middle of my second summer with my M550 in San Antonio, Tx. We have had, and are still forcast to have multiple 100+ degree days. I park in the sun at the golf course 4-5 days a week, and return to the hot car, where I roll down the windows as I approach. My car is Sappire Black Mettalic, with black interior. Windows are tinted. I have no problem cooling the car. By the time I load my clubs and drive out of the parking lot, very cold air is blowing, and the seat ventilation can be felt on my already wet shirt and shorts. Within several miles, the cabin is cool and comfortable, without using Max Air, with Auto set on 70 degrees. I have found no problem with the air conditioning system. Sorry others are having a problem. I think this car cools as well as my Mercedes, or any of the other cars I have had. Just my $.02.

I posted this before about my 2017 540i to cure my AC issue. They repaired it. BIG FOAM blocked vents ... they replaced BIG with small foam - AC works well. This is what I have: 6499000 WT TO REMOVE THE FOAM FROM BOTH SIDES PER SIB640817 16684 WB FC: 6400315900 26039 VERIFIED CUSTOMERS CONCERN, REMOVED FOAM PADS FROM BOTH CENTER VENTS PER SI B64. 08. 17. __________________

Failed A/C Evaporator
Hello All,
I was on the same boat earlier too. The A/C was weak and was sent to the dealer back in 19 and they replaced evaporator and some other parts under warranty and exactly an year later i suspected the same problem and dealer diagnosed that the A/C Gas was way low than normal, checked for leaks and SA said they changed some valves and re-topped the GAS. It worked fine for couple of weeks before going completely broke. Dealer kept the car for a week and returned it back yesterday stating that a new Storage Evaporator and some other part has been ordered from Germany and since the old part are superseded and this is a new design which will take 7-8weeks to arrive. Can you all advise what can be done? I mean its driveable, may be just for a quick grocery run's. Would calling BMW help with any loaners or rental or am i on my own? (have a road-trip planned - hence the ask) Mine is 18' 540ix with <16k miles on the clock. |

i also see that the g30 540i auto is not that perfect as my previous f10 535i. it takes much longer to reach set temperature under non recirculation and auto mode (already adjust the upper body temperature to low, same setting for compare); not sure what is the issue; i guess auto engine off may delay the cooling time as it slows the cold air speed when engine is off. my f10 does not have engine auto off function. also i noticed that the air out temperature for f10 is only 37.5 degrees F, however g30 is higher to 42 degrees, not sure if the Refrigerant is also different which make the difference of auto mode not that effective to lower the cabin temperature to set temperature. for g30 when set the temperature to cool the cabin, i found the foot temperature is high, i think this is one other reason that delay the time for the cabin temperature to lower to the set temperature i read a long thread already, but can not find a solid answer, only knowing there is kind of "software" update can help, not sure if the software is really update..my 540i is built 2018, january, not sure if the software update is effective to this model......this bother me a lot as i lived in southeast asia, quite hot in summer say to 95 to 100 degree. thank you if anyone has any proof solution for this, some engineer said they can edit the code to stop the hot air from feet area, however i don't want this kind of solution, i expect that there is a total solution from bmw to fix this....appreciate all for your time reading my post; have a great day |

I used 25% ceramic on all the windows but obviously I'd do the Air 80 on the windshield.
