How to stop AC from coming on during start?

How come this is not the default operation?

I read on an M3 forum site that if you press the M memory on the seat prior to turning off X5 that it may remember the last setting of the aircon/fan speed, gonna give it a try....nit sure it will apply to the X5 and thanks to Q7silvers feedbacj and all

That's how my E46 climate control works. It keeps the last setting. My E53 always turns on. There must be a coding to change this behavior...?

I'm gonna be watching my X5 for this. I don't remember exactly how the E46 worked for my kid, but I recall that I thought it annoyed me. I bought an X5 on 02/16, and I will be looking to see if the life support system is as annoying.

I never found an answer to a permanent "off" feature upon start up. So, what I just got in the habit of doing is as soon as I turn my key to position two I turn off the vent/fan system and then turn the car on.

I will admit I haven't studied this entire thread, so I may be repetitive...
I never have A/C 'on', in any car I've owned, in 50+ years of cars.

On our '01 3.0 X, I usually have the vent 'on', low fan speed, when I start car.

Then, if I don't use A/C, it stays in that mode or whatever non-A/C mode I use on the drive, and then whatever non-A/C setting on turn off & next start.

When I want A/C ,I hit the snowflake button and I have A/C...

When I am running with A/C on, I turn it off as I climb the mtn road I live on, and after parking, it is simply on vent position I want, fan speed I want and no A/C.

Dunno why this comes up here on the jukebox so often...

If one likes 'auto' HVAC, great. If one feels that constant 'auto' (A/C), is good for seals or compressor, great.

I like manual, and we have the step up from basic HVAC system in our '01.

13 1/2 yrs & 98k miles later: the air is freezer cold, no compressor hiccups, etc.
But, I only run A/C when I want air, or defrosting.

Not sure what I did but my climate control remembers the last setting after I turned off the car just like my E46. If I turn it off, it will stay off after I restart the car, etc... I must have changed or reset something in DIS while looking for engine idle management. So the climate control is programmable.

hey guys I fixed the problem by replacing the heat control

This feature is coded. I disabled it on my E53 with IHKA. The "feature" is enabled from the factory to always turn the blower on at minimum speed after the vehicle goes to "sleep" even if you manually turned the system completely off. There is also a "feature" coded that always turns the AC on and turns off recirculate regardless of the last setting when the vehicle was turned off.

If it bothers anyone that much, the best solution is to google NCS Expert, NCS Dummy, buy a cable, and code it off. It is not a Car/Key Memory programmable feature, so the dealer will be of no help.

Only way I know of to do it is turning the ignition to the most onward position, turning off the vents, and then starting the car. I believe it works everytime but I usually just fire it up and turn it off right away on warm up because I don't remember to do it with ignition on.
