Air Conditioning...THE SOLUTION!!!!!
3 Attachment(s)
For all us us with poor airflow on the side vents...I have discovered the problem. I have searched the manual, asked the dealer and played with every menu and finally today as the sweat was dripping from my face I discovered what the dealer couldnt.
The first photo shows the temp inside my car today. The second photo shows how my idrive was setup. Inside Climate- "AUTOMATIC PROGRAMS" there are three settings: SOFT MEDIUM INTENSIVE Next to these settings is a scale that an be adjusted up/down, it was set at the maximum. I even tried adjusting this higher and lower and it didnt really affect the airflow. I have played with this adjustment a dozen times. Except today, I accidentally went past the zero setting and noticed the gauge turned blue....WOW....EUREKA!!! I HIT THE MOTHER LOAD!!!!!!!!!! So now look at the third image...I set this scale at the highest blue setting and now I have air flow on the side vents. YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!! I still dont really understand what it all means, I guess the red settings are for the heater...anyone understand the logic here?? |
Coooooooollll! (literally) !!!!:woot:Even the persons bod is now blue !!!

Nope I don't have my car but I am gathering these facts for when it arrives.. In Sydney at the moment the warm settings will be used unfortunately until September !!!
|
Now for the bad news...my wife says the "ac girl" must go.

Doesn't red denote HEAT? You might have been using the heater with the original settings....

IDrive, (the driver crazy) ...
How did we ever get along for 50 years having to push/move a button or switch for HVAC in our cars? :rolleyes: ... :rofl: |
I seriously wonder.........what was wrong with the old way (buttons)? My AC works fine simply because I don't have to fine tune it. When I want cold, it gives cold. When I want warm, it gives warm. Why does it have to be "mildly cold, slightly cold, or very cold"?

As I understand it, you are adjusting the comfort zone setting for your "upper body region". You can make it much warmer then the auto temperature setting (4 red bars) to much cooler (4 Blue bars).
|
great work X5FX! I'll make that the first thing I configure on my car when I pick it up next week. IT's 110 in phoenix now and I'll need the most I can get from it!
Good find! |
i did that last week but i didnt think it made any changes in the airflow
|
This adjustment merely serves as a driver preference to adjust against the temperature setting. My 4.8 has been set to coolest (blue bars) since delivery of car 7,500 miles and has had no impact on the poor airflow or failure to properly cool the cabin. The problems as noted on this board are fan speed, quanity of air and delivery points of the air from the front dash, particularly the failure to deliver air to the mid to lower areas on a consistent basis. I have seen this complaint posted on several boards all relating to the new e70. BMW has no response and unlike many of the other issues where tsbs have been issued, there has not been one yet on this issue.
|
Once I made this change the air flowing out of the side vents is now as great as the center vents....it is a significant difference! The car now cools. Did you make this setting for both driver and pass sides?
I am in Louisiana where it has been averaging 94 w/ 100 percent humidity and the difference is night and day with this adjustment. |
Yes. I have had the setting for both since taking delivery of the car. I am in Bham, AL with similar heat and humidity. This is how I demonstrated it to my dealer. Put all settings to full speed, turn on max cool at 60 and note that the air bairly blows to your face from the center. Does not even move hair. Tried it in 3 e70s at dealership and found same issue with all 3. Lexus gx and mercedes e have no problems with air flow or cooling/heating.

I use this setting when I first get in the car to cool it down, then gradually back off....now that I have solved my problem I should be able to just switch to auto. I'll let you know how its going after today, my first real day to test this as I just discovered this yesterday evening. |
It just drives me crazy to see all you folks troubleshooting the E70 and I don't even have mine yet. I'm trying to familiarize my self with all these issues so I'll be ready when I get mine. I just appreciate all of you who spends the time sharing all these valuable information.
I want my E70!!! |

i've always had it set to "blue"/cold.
my solution is to shut off my rear climate control. when i do that, the a/c output in the front DOUBLES... but d*mn, I paid extra money for an option that reduces the performance of my x5. sheesh.
|
yes, I noticed that too.
Since I discovered my issue in post #1, I have been able to set my AC on "AUTO" and "soft" and leave the temp on 68 ...I dont ever have to touch it again. The temp outside has been averaging 95 degrees w/ 100% humidity and when I get in the car it takes about 30 seconds to cool it down, then the fan gradually backs down to a barely audible sound and it maintains the temp. BTW- the side vents have strong air flow too. Now if I turn on the rear AC its a totally different issue, and yes I agree the air volume drops about 50%...WHY? I've been telling the kids..."shut up, sweats good for ya...I'm very comfortable up here" Better question is WHY did we pay extra for this? BMW- you got some splaining to do. |
I cant understand why it has to be such a difficult and comlexe car.Even the dealers dont know how to operate it.I am wondering how safe is it to drive and change a radio station by using the i drive.Pointless function the i drive is.
|
Actually I find the iDrive safer than the traditional method...and very easy to use btw.
I wouldnt want to go back. |

Have you find out the meaning of "Adjusting temperature for the upper body area"? It confuses me by setting temperature for both "driver's side" and "driver's upper body". Also, I don't feel the air to footwell at all, no matter how the setting is. Do I do anything wrong? upper body |
mines in the shop right now looking at the ac issue I described in post 23 (rear ac cuts airflow)

Is there anything in the owners manual on the blue vs red? I couldn't find it..

May be I should set it to have 4 blue bar? But, still, I don't understand the real meaning of blue and red. |
yes put it on 4
btw- is the rear air on? if so turn it off. |
Why do these damn germans have to make things so freakin complicated. It's a/c for goodness sake. Don't get me started.:nanana:
|
Not sure it was mentioned in this thread but the purpose of this function is to allow you to customize the impact of 'soft' 'medium' and 'intensive' for the driver and passenger.
|
I have not had any AC issues in the X5, but I remember reading about the red and blue stuff, and if you had an E53, you remember that the dials on top of the vent do the same thing. It either makes the air slightly colder or warmer. So the HVAC in the X5 works excellent, even with the rear climate on 100% of the time. I haven't found that an issue.
But in the X3, it feels like all the cold air is escaping. It never gets comfortable in there :dunno: Glad you got yours fixed x5fx |
so you dont notice a difference when rear air is on vs off?
I have 50% less airflow when rear air is on + the a/c is very loud |
Am i missing something? The E70 manual pg 103-104 explains all of this. http://www.xoutpost.com/pdf/e70/2007%20X5%20(E70).pdf. What's the problem?
|
no not much. IIRC it is set to 70 degrees and on the first fan power...I like having the circulation

This is an old thread...but read post #1. This is not explained in the manual. You would have to go into the idrive and play with the settings to understand. "What's the problem?" here ya go: When the rear AC is turned on, the front ac loses 50% of its airflow. Also the system acts as if its possessed. The airflow just changes randomly...turns warm, air stops flowing from side vents, flow surges, blower volume is at least 200% louder, etc.. I have to lower the auto setting 9 degrees to stay somewhat cool. As long as I keep the rear air turned off the system works great. I can set the auto at 78 degrees and I stay cold...but as soon as I turn on the rear air the ac is a POS! and the cabin does not STAY cool. mine is at the dealer now for this issue. |

If I Recall Correctly

Actually i did read it and we figured out those settings in our 2006 5 series after reading the instructions in our manual the first week of ownership.
For the E70 Under the Air distribution, manual on page 103 it explains clearly that "you can route the airflow out into the vehicle interior with various programs and those programs are listed for both driver and passenger. I guess using the rotating button on my X5 led me to recognize that it was the same operation only done electronically via iDrive on our 5 series. Maybe that why we never ran into the problem as described. We did notice that some minor adjustments were required to optimize climate control for driver and passenger. But again the E60 manual helped in this regard as well. As far as the system doing crazy things, i'm not surprised by that and i hope that part get's fixed asap. Kepp us posted regarding the outcome.

I'll let you know what the dealer says, but I dont have much hope they are going to solve this. btw- I am not the only one with this issue. |
been at the shop for 2 weeks and they just called and said they cant find anything wrong.
|
wow, that sucks. Two weeks? Jeez.
I hope you give them a bit of your thoughts when you go pick it up....;) |
they put me in a 328, so it wasnt all that bad...but Im still not happy . The sa said he would drive it home tonight and see what he experiences, then he'll go back to the shop. I'm not holding my breath though.
btw- dropped off at 8am on 4th, so not quite 2 weeks yet. |
Hey X5FX - did you ever get your A/C issue resolved? I have a 2007 4.8i and with the temperatures here in TX starting to heat up again, I came across this same issue today. On a drive between Dallas and Austin, when I had the rear A/C on, I had almost zero air flow in the front. Even on "Max" A/C. I had to continuously switch between front and rear so that I wouldn't sweat too bad and so that my 3-yr old in the back wasn't too uncomfortable. Given the cost of this car, this is unacceptable.
Oddly, after getting home and allowing the car to be off for about 30 min, I tried it again and the air flow was even throughout the car. So a reboot of the system and it's working at the moment. Is this a computer issue? Maybe the A/C program is buggy, resulting in the "possessed" behavior of the A/C system. |
the only solution I found was to tell the kids if the touched the rear ac I would punish them...they can sweat, the pioneers survived.
not bad for a $70,000 vehicle huh. |
The middle setting in your second photo can provide a balance of both temps.
What i also i figured out is that to adjust these settings is very easy. In fact that window comes up via voice control. Like everything it's easy when you know how. Now if i could just get my Nano to stop scrolling thru the songs.......:rofl: :rofl: |
that setting has no impact on the rear ac. The problem is when the rear ac is turned on, the airflow drops 50%
|
Now that you figured out the A/C, you can get blasted in the face with the smell of moldy socks!! lol
|
The A/C is pretty bad in the E70. It was bad in my 2007 3.0si, and it's almost as bad in my 2008 4.8i. It was worse in my 2006 E90 (330i). It seems like all "new" models have über-crappy climate control systems (must be software related, again!)
No matter what setting I use (AUTO, more blue bars,etc..) I have almost 0 airflow out of the side vents by the driver & passenger front windows. The air is pretty cold, but unless I use MAX A/C, the airflow is never really strong. The BIG problem is that on MAX, you cannot hear the radio, and don't even try to have a conversation with anyone in the car. While I "appreciate" BMW Engineer efforts with their i-Drive "options" cough, cough, for the A/C...they are just confusing, poor and honestly they just don't work. Mercedes, Lexus, Audi and surprisingly Ford all have superior Climate Controls compared to BMW. |
Although I found the blue and red bars the first time I played with it, I still find the whole idrive-integrated climate system to be confusing. Too much detail and not enough difference, in my opinion.

I couldn’t agree with more.:thumbup: :thumbup: :iagree: |
Does anyone know whether a software update resolves this issue? The issue occurs intermittently for me, and it seems a reboot of the car makes it go away for a while. That makes me think this is a bug in the software (I'm assuming the A/C flow is controlled by the software - please let me know if you think otherwise). Has anyone had their software updated and seen this issue go away?
|
it makes sense to me. Hot air rises. No need to keep the higher side vents flowing when heating. Perhaps the side vents becomes activated to cool the warmer less dense air, since cold air sinks.

Reviving this thread. Since this morning, my AC behaves pretty strange. No matter what settings I try within the idrive climate settings, nothing helps. All it does it blowing hot air through the front window air vents. Since it quite cold over here, I would have appreciated some heat coming out of the footwell air vents :) Car is going in on monday to check .... |
