Climate control turns itself on

[BobbySpeed]

So, when I get home and park in the garage I turn all of the accessories off before I turn the key and shut off the car. Next, I lock the doors so my kids can't get inside and play in the car. In the morning I open the garage door, get in the car, turn the ignition key to start the car, and my automatic climate control is on (sometimes). What gives??? It's a little too automatic!

Just picked up the car from service. P-car service manager stated that it's automatic, and it is supposed to bring the car up to the temp even if I turned it off before shutting off the car. Technician said he re-programmed the head unit for me anyway- just in case(?).

We shall see.

Can any one comment on how their system works?

BobbySpeed,

Mine works the same way (2006 Cayenne S).

I have the two-zone automatic. I switch it off before I turn off the engine and it does turn itself back on when I start again later. I've read the manual carefully and did not find anything about this.

It would be on at the lowest blower setting.

This "feature" has been bugging me lately too and I'm wondering if something is broken. If it was intentional you'd think Porsche would say something about it in the manual. I've tried it with automatic recirculation on and off and it behaves the same way.

When your tech "re-programmed the head unit" did he just reflash your system software with whatever latest version or was there a specific modification done to modify this "feature"?

Maybe this is what happened (from the owner's manual):

Remote Control

In the multi-purpose display of the instrument panel,

you can set different variants of locking and unlocking

the doors and the rear lid as well as the

check-back signal when locking and unlocking the

vehicle and save them on the respective remote

control.

f Please observe the chapter “COMFORT” on

Page 116.

The air conditioner settings are stored on the respective

remote control when switching off the ignition

and locking the vehicle. The “Air flow OFF”

setting is stored for approx. 60 minutes and the

“Recirculated air” setting is stored for approx.

20 minutes.

I have the 2-zone automatic climate control. I set said climate control to "Off" and then set the memory on my comfort seats. I heard the audible ding, and would expect my car to start with the climate control off next time I start the car; however, the climate control comes on at the lowest setting. This was described by my P-car service dept. as normal. What can I say? They are the experts(?).
