G30 (2017 - Current)
The next generation 5 Series, chassis code G30, arrives at dealers in February 2017. Looking like a scaled down 7 Series and riding on the CLAR platform, the new 5 Series will have a focus on lightweight and sporty performance. Engines options will come from BMW's new B family for the 530 and 540 and a turbocharged V8 for the M550i. Read more about the 2017 5 Series

Setting them all to 72 should work the same in all vehicles. Get me to 72 as quickly as possible then maintain it.

I have to set it to 60 for it to get me as cool as my wife's Lexus gets me when it is set at 76, and the BMW takes much longer to get it to that point even set at 60.

What part of "Automatic" is one of us missing?
Auto setting does not work in very hot climates. Forget about the 35 previous vehicles. I have had 3 successive BMWs and a number of loaners. You have to use MAX AC to cool the car down on hot days. That's it.

Look, this AC is not efficient by any means in hot weather. At 68 deg, the fan is way too loud (intensity set at auto 3) even after driving 20+ mins.
I can somehow deal with that but what pisses me off is how it decides to change the air vent temp to what feels like 75-78 randomly.

I am going to go to Home Depot and buy a thermometer to start measuring stuff to get some hard data.

Right now I am just fluctuating between 68-69, on auto, fan at 3, vents neutral everywhere.

This is the first car I have ever created a thread about the AC. I don't remember the 535i being this bad. My ex drove that one and she never complained.

Well something is different between our cars because if I shut the 2 rear seat vents, there is a substantial increase in the volume of air up front. It's not subtle.

As a 530e owner, I would strongly advise doing that.

I live in hot greater Phoenix (but not humid). If the car has been garaqed, the auto setting works fine. If the car has been sitting in the sun for an extended period, then I turn on the max AC for somewhere between 2 and 5 minutes and then go back to automatic. That seems to work for me.

I do use max air. If the interior is 100+ degrees the automatic system should do that for me.

But most of the complains are that the system really takes a long time to cool down in any setting, and in my 45 minute commute I still have to set it at 65 or lower to maintain anything approaching comfort.

Please don't tell me to forget the other vehicles. The other 35 all worked better than this one, regardless of settings. I live in F'ing Houston Texas. The A/C is important.

If you are happy with yours, great.

+1

"Auto doesn't work in hot climates". Really? What kind of logic is that?

I will do what I can outside of the AC system to help the car out.
1. tint the car. 2. use a sunshade. 3. open the windows upon startup.
The rest is on the car. Get cabin temp down to 72 as soon as possible using whatever settings it needs to do. Then maintain it for the rest of the ride. I don't care about max intensity of the fan, i don't care about air vent temp..it's not my concern.

You are reminding me of a not so pleasant anecdote, with my 1985 Mustang. We traveled between Phoenix & Las Vegas, mid day, August. The outside temp was ~110-115. Ford cut costs, by not supplying a sliding cover for the sun roof. By the time we hit the stretch of Hwy 93, between Kingman & Las Vegas, we managed to get the interior down to a (NOT) comfortable 93 degrees, for the entire distance. (I even tried using 4th gear, to run the compressor @ higher RPM.)
The best A/C was in a 99 Lexus. Our BMW's will keep up in 100+ degrees. But, as you note, it takes awhile, if the car has been sitting in the sun.

Yeah, but cruising into Vegas in a Mustang during younger years must still have some positive memories!

So I have been trying manual mode for a couple of days.

Same 68 deg temp, fan speed 6/8. air flow direction = upper body

Car starts blowing nice cold air and out of nowhere..air feels warmer..like it's just the fan, no AC.
This was just earlier (around 9am, I was facing north, coming to a stop sign). Once I started driving again, air starts getting colder. I am in Sport mode.

Something is wrong. I need to figure out what triggers it.

EDIT: just drove it to get some coffee. cruising on the highway...65mph...cold air...warm air...cold air...warm air. all during a 8 mile trip.

You mentioned the outside temps were in the upper 60's. This is consistent with where I find my system just doesn't know what to do- from around 65 to 73 degrees give or take.

Nope. Temps are 90+.

I called the service department yest and asked if this is normal, he said no but also told me to try turning off auto circulation. Tried that on the drive home and it didn't work.

You may just have a refrigerant leak. Has that been checked?

Does anyone have these issues with the big engine, rather than the middle engine?

Your car has an HVAC issue going on -- not normal at all. Take it in for evaluation and service.

Update:
So I took the car in to have them look at the AC system.
They gave me a brand new (80 miles) X5 as a loaner. I have that set at 72, auto everything...i am comfortable. no random lukewarm air..nothing. just comfortable cold air.

Fingers crossed on hoping they can figure out what's wrong with mine.

My service manager told me there was a software fix for AC that changes the compressor settings. I’ll let u guys know as I’m scheduled to go in for svc in couple weeks

Please try to get a description of what specific issue the software mod is supposed to address. I believe there are several.

More A/C:

There's lots of interesting info here.

I bought this car (X1 2.8XI in November, 2013. I have never had a problem with the AC here in South Florida until recently. The vehicle seems to have issues with electrical storms that strike close by. It will flip all of the Low Tire Pressure indicators off thinking it has 4 low tires. I Just reset it and drive off. One day, I noticed a noise and found the sun roof partially opened. I never open it. EVER! But it was open. I had to figure out how to close it. Then I noticed that the AC was blowing warm air. In South Florida/West Palm Beach, I pretty much have to run the AC all the time. My wife is sick and doesn't drive any more. She depends on me. SO when I see her playing with the vent controls, I know there is something wrong. Before, I could always fix it. Seemingly, not now.

I used to get in, start the engine, roll down the windows and set the AC to Auto-High. Which then sets the temperature to 60', opens the vents automatically and over rides any other auto settings I had on. When the cold air was done, I would just set it to run on the other settings. plus it turns the cabin fan on "High" or maximum. It no longer blows any cold air. I have over 50 years experience in residential/commercial air handling. Its all the same. A car is like a small home with varying loads. As long as the compressor, evaporator coils, fans and refrigerant loads are big enough, the space will cool. Just like the heat of the engine coolant will warm the space. There are far more BTU's available in heating than in cooling.

It acts like my old 2001 325IX wagon when it was low on gas/liquid. All AC systems leak very slowly. WE are encouraged to take it to an "Expert". You don't always get the "Expert" on the first try.

So one day, I was buying filters for my John Deer Tractor at the local Advance Auto Supply when this beat to **** Ford Mustang pulls up next to me. The Mufflers had fallen off. It was a hot summer day in Hyannis, MA. The guy goes in and buys 6 cans of "Quickee AC Recharge. Connects it up, no evacuation suck down, charges it up and drives off. Well,, if he can do it, I can do it. 6 month later in Florida, the AC stopped working. So I followed the directions on the can and it was still fine when I traded it in.

It seemed like the same thing was happening. Low on Gas. So I checked the pressures and how full it was according to the instructions on the can. It had plenty of gas.

The High Pressure Supply port on my X1 is in the right front side/top of the radiator bracket. The Low Pressure Return port is on the drivers side firewall. When the system is properly running,, the gas return should be cold and the high pressure liquid line should be HOT. On mine, both are hot. Like something is stopping or restricting the flow of refrigerant. The hose on the Freon can only fits one port, The low pressure one on the drivers side firewall and goes to the compressor. Its almost idiot proof.

Unless you take it to a shop like AAMCO, they just send it out because most BMW type repair shops don't want to hire and pay a real AC technician. So they just send it out. You take your chances on experiences with the parts changers. (Ones who change parts until it starts to work. You pay for their training. Most of the really good AC Mechanics won't touch a car with a 10' pole.

Thanks someone for posting the ductwork. This is NOT a difficult troubleshooting problem.

Sorry. What should I have left out?

Today, it happened to be 77 Degrees in W. Palm Beach. I don't know what the Cabin Temperature was but it was blowing cool air. Maybe tomorrow if it is in the 80's or 90's, it will blow warm air. If it does, it means that it isn't evaporating properly. It used to work properly. Suddenly it doesn't.

If I can't get any answers here, then why would I think that some part time Yahoo's at some dealership shop or some AC shop will have any better idea of what is wrong. From what I have read here, you guys think outside the box. I've been on this forum long before the date it shows I joined. In 2013. My first BMW was a 1996 or 1998 3i8 T! My next was a 2001 325IX Wagon that I put 153,000 miles. Neither ever had any AC problems. Except the 2001 when it ran ow on refrigerant.

I'm not the Rube you think I am. Besides it is now my Invalid wife's car that she can no longer drive. I never had any problems with my Ford work vans.

Thanks. If some of the really smart and experienced people here can't help me. I guess I will have to throw myself at the mercy of the parts changers. They start with the compressor and work down to the cheaper things. Or tell me to buy a new car. That's what I used to see in the Plumbing & Heating business. Building isn't heating enough when it gets cold and it always has since the boiler was replaced four years ago? Replace the boiler. That solves everything.

Have you checked your engine coolant level?
