A/C and Climate Control System not on when Starting Car..
So, all of a sudden, one day, when I turn on the the car, the climate control system is no longer on, and I have to press the auto button to start it. This is not just the A/C or blower, or one component, it is the entire climate control system that just isn't on when I start the car.
This happened one day out of the blue; not after I did any coding, or anything like that, it just happened. Any ideas? I've gone into the ECU via E-SYS and made sure that the settings for A/C remember last setting is activ and all that.

Seemed like when I got my car coded by Shawn Sheridan, that most functions required tagging the same item in 2-3 modules in E-SYS - but I am no expert. The other odd thing that we experienced was that for the life of us we (more correctly he!) could not get the coding to have the mirrors to fold automatically when remote locking the car to work - tried numerous approaches and again had to hunt down more than one location in the coding to change. We decided to leave it as is and sure enough, when I got home, shut the system does one more time and re-started everything up and lo and behold it worked!! Almost as though the software needed a multiple reboot to take the new coding as std. Again this is not very helpful but does seem like your issue would most probably be related to prior coding and any recent alterations you made in E-SYS? Apologies fro rambling!!

I don't think I changed that, but I can check. So we're clear, I should set that to nicht_aktiv to make it remember the setting each time?

It should be "aktiv" so that it remembers from previous shut down.

This line is kind of like a double negative. It's titled MEMORY_OFF so you want it not active so memory is on.
