Unless they've changed it ICE is 15 minutes. That said I haven't had one complaint from the wife that does a remote start prior to leaving her classroom and out to the car even when it was 110 degrees here in Phoenix this summer. Not sure how long she runs it but guessing about the 7 to 8 minutes of walk time from the classroom to the parking lot.

Her 2017 X5 with no remote start was a crap show. It was max A/C and even then it took 10 minutes plus when originally starting the drive home before it cooled off.

my wife has had BMW since 2009, but she is still impatient with getting the cabin to temp. on hot days, she’ll blast MAX A/C as soon as she starts the vehicle. on cold days, she’ll raise to thermostat temp to get it to start heating faster. maybe it’s placebo for her, but I know she likes the physical feeling of the air blowing on her face. for me, the increase in fan speed at the beginning is enough and still gets the cabin to temp in what I perceive as an acceptable timeframe, but everyone’s tolerance is different.

It is a terrible design.

You remote start a $25,000 Honda Civic and if the interior temp is very high, the A/C will start at its maximum potential to lower it as soon as possible.

You remote start your $100K+ BMW and if the interior temp is very high, but your last setting was AUTO-VERY LOW, it will try to cool down the cabin in VERY LOW.

Totally defeats the preconditioning purpose.

Before I get a “go buy a Civic”, I really like most of BMW features, but can’t get over how terrible the A/C is.

I really hope that’s just an iDrive 8/8.5 bug because when I open the door just 5 minutes into preconditioning when the temperature delta is large, the fan speed is often much higher than my AUTO LOW setting.

Could be the version he is running, or just his perception, as we have had other LCI owners say it works just fine and seems to operate as the iD7 Auto operated.

I think a lot of it is often perception, preconceived notions, bias, expectations, etc. when we talk about the A/C versus what it actually happening.

I thought that button you saw is for windshield defrosting max, no?

BMW HVAC doesn’t always do what G05 does. My older bmws will do max fan in auto. Basically there is only one big range, min to max. For center vent has a physical dial for direct adjustment, instead hidden behind a few clicks of menu. Here is where I prefer the older bmw implementations.

No experience with bmw precondition or remote start prior because they are all manual. However, other brands, QX60 and MDX, they do blast at full max AC in remote start is situation calls for it. And no separate center vent adjustment. They works better IMO. I hardly need to touch the HVAC control.

Yes, windshield defrosting as a correction vs heater. Either way 💯 useless here in Phoenix.
