does i3 climate have this sliding adjustment blue/red? i dont recall, but ive read about it on other bmw models.jadnashuanh wrote: ↑Tue Nov 19, 2019 4:26 pmWhen in auto, the fan function is more of an aggressiveness adjustment. Setting the mode to one of the ECO ones will affect how aggressively the car tries to maintain. The car is smart enough to notice the windows fogging up, and even if the a/c is off, can turn it back on to help dry the air. BMW has said that driving with the windows down above 25mph and the a/c off is less efficient than letting it run with the windows closed because of the additional drag from having them open. The sliding adjustment on the vents will offset the temperature out of them either warmer or colder than normal, so, say it's set to blue end, it will be cold, pretty much regardless of where you have the thermostat. That can offset say the heat from the sun on a cold day where you want your feet warm, but some cooler air in your face.
I have an 2018 tera interior and it's still just a sliding open/closed system.Fisher99 wrote: ↑Sun Nov 24, 2019 10:48 amMy wife's 5 series has the blue/red on the vents and works exactly as he stated. However, my 2014 i3 does not have blue/red. The vent controls simply turn the vents on/off. Maybe it was an option on a higher trim level on the i3. Mine is a Giga. Maybe on the Tera?
The fan is "managed," but I was happily surprised to find that Auto mode stays engaged even after a manual adjustment is made to the blower speed. On many other cars with Auto climate function, the Auto indicator turns off once a control is touched, which I assume means the system has reverted to manual control.
Wow, that is a smart system. I was afraid that is was more basic as I always see it on the minimum, but will definitely take a look at its behavior. Thanks!jadnashuanh wrote: ↑Sun Dec 29, 2019 10:00 pmThe car will adjust the fan, but maybe not to your liking. IN that case, you can adjust it manually.
Also, FWIW, the car will also sense if the windows are fogging up, and turn on the a/c, even it you've manually turned it off to help dehumidify the air unless it is too cold outside for it to function properly.
Sometimes, the car is too smart. But, once you've got it dialed in to what you like, mine, at least, seems to do a pretty good job. Keep in mind that the i3 is trying to manage power, so it might choose a less aggressive reaction to temperatures than a more typical similar system in an ICE.
SOme try to save energy by shutting the a/c off in the summer and running around with the windows open...BMW has stated that over 25mph, the drag induced by having the windows open is greater hit on economy than running the a/c. It might be useful initially to flush the super heated air after being parked in the sun, but once that's done, shut them, and let the HVAC do its thing.
thats great! That was my “complaint” as on my old car whenever you changed the fan speed auto would un trigger.eNate wrote: ↑Sun Dec 29, 2019 10:13 pmThe fan is "managed," but I was happily surprised to find that Auto mode stays engaged even after a manual adjustment is made to the blower speed.

One control the i3 sorely lacks is coordination between the blower and the Bluetooth phone. The Tahoe I drive at work automatically quiets the noisy fan when a call is made or received, and makes a much appreciated difference.
