Pretty sure this is normal for all 5 series. Been posted about a lot over the years. Keeps the humidity low, car more comfortable.

 

imo this is how a luxury car should work, you set a temp and the car at turn on check interior and exterior temps and with fan always on applies A/C or heat as needed to meet setting. So what's the big deal about a car always trying to satisfy your every desire?

 

Because that's not anybody's desire. I believe that is the standard operating mode, at least in the new 5. It even says that in the manual and my dealer said it always comes on. It really makes no sense though. I don't understand the reasoning behind this "feature." I mean if the car can remember the last temperature that I set the climate control to, why can't it remember if I turned off the a/c?? At least make it configurable as an option through the idrive.

 

It's been explained multiple times. The AC goes on to keep the interior humidity at a low level.

 

It does no such thing if 95% of the people turn it off as soon as the car starts. Who has it been explained by? I looked through the manual for an explanation, but actually it doesn't talk about it being automatically turned on at every start at all.

 

I keep mine on 60 all of the time, I can't get enough of the A/C

 

I tend to agree with these posts. I get the humidity thing, but Its may and in the 50's here in the morning. Do I really need the AC to turn on at 60? Its not a big deal, add me to the list as someone who turns it off 95% of time. Im sure that will change in month, but would much rather have comfort access on the door handle as standard (as the g37 and m37 offer as standard) than AC that turns on.

 

If I shut off my A/C it stays off even if I turn off the car and turn it back on a few days later.

I am not sure why there would be a difference between VIN's.

When I had my X6 it would stay off as well.

When I had my 6 series, it would turn on automatically.

:dunno: But I am sure my 2011 F10's A/C stays off until I enable it.

 

Just because that little light is on does not mean the air conditioning compressor is running. I only turn it off on those days i choose to run with the windows open.
