AC performance vs prior generation

It seemed to be a pretty common issue with the 14-18s having weak AC performance especially in hot climates such as Texas and Arizona. Does anyone know if the G05’s perform any better?

I believe that the AC capacity tests and acceptance criteria are identical. www.NewTIS.info.

The air conditioner cools extremely well. If you adjust the settings correctly it will freeze you out in no time. I have not seen anyone here or on the other forum complain about performance once they understand how to adjust the air flow temp.

My '15 F15 was pretty cold once set correctly too. I think many people didn't realize you can adjust fan speed separately while still keeping temp in AUTO mode.

I did not realize that even having studied IHKA closely. In the only technical description of IHKA from BMW that I have ever found, I find this ...

“Air Flow Control/Blower Speed Control
Air flow control is dependent on the following settings and parameters. Blower control automatic mode If automatic mode has been activated in the IHKA control unit, the blower speed is controlled in accordance with a characteristic map depending on the required nominal temperature and the interior and ambient temperature. The relevant automatic blower control is switched off by operating one of the blower buttons of the IHKA.”

I thought that meant that if one selected blower speed up / down then AUTO is disabled. I’ll have to check when next I remember while driving.

When I want to vary the apparent AC ‘power’ then I toggle AUTO through characteristic maps Gentle, Moderate and Intensive, but the AUTO mode lighted button remains lighted.

Even more importantly many folks don't know that they can/need to adjust the temperature of the air coming through the vents to make it colder. Without doing that the air coming out will not be as cold as it can be.

i thought my 19 x5 ac was weak.. then i found out that red/blue dial is now buried in the climate control menu and it's set in the middle by default. you have to move it toward the blue area and it quickly freezes you

i will say i absolutely hate the temperature buttons. i wish they still had the rotary knob

I have had a great experience with my AC in the new model vs my '15. Very strong performance in the deep summer North Carolina heat.

I have a 2018 X5 Diesel.

We live in Oklahoma.

How do you get the airconditioning to cool properly?

Our i3 electric does a much better job.
Our Honda CNG with automatic temperature control, does a better job.
Even out 2002 Suburban does a better job. We leave that at the Buena Vista, Colorado airport. Even our Cirrus SR22 TN has better airconditioning.

Is there a software update?
Is there a secret setting?

Sometimes it works great, then falls off.

Most of the time, it is just plain lethargic.

I have the fan speed set to high.
I have the rear airconditioning set to off.
I have the blue knobs showing.

Other than that, the Diesel X5 is great.
Well, except for the Blind Spot Detector.

Any help would be very helpful and appreciated.
The dealer says that is it working properly.
They loaned us an X3, while they looked at our X5.
The 2019 X3 air-conditioner worked great.

Somethimes, ours works well. Then falls off a cliff.

Sometimes the heat comes on in the middle of the Summer.

If you want the dash vents to blow colder air, make sure you adjust the knobs accordingly. Adjusting the fan control manually will still allow it to keep the auto temperature, just not fully control the fan speed.

Thank you

Is there a coding change I could make on the 2008 X5 Diesel?

I have the equipment,
I have never coded the X5.


Can we change the programming on the airconditioning for more comfortable levels?

Thanks,

/s/ Tom Milam, Jr.
