Secret AC menu
I'm no sure if this is known yet, but I'm very sure the
#6 menu is the engine coolant temp
And I just found out today, the
#8 menu is AIT
Can anyone else confirm?

It worked for me last July when I was having issues on the way back from Miami after buying my ride? I don't think the temp settings have anything to do with it. Just hold down the AUTO button for 10 seconds or so.

Tried to again today when I drove to lunch, gave up after like 30 seconds, has to be something to do with the de-optioning as this car progressed from 03-06, but I'm wondering why 06's have it if 05's dont.

it is not number 8. because it behave like scanner, but when you put the scanner and use the AC method. you can see the diffrence between the number. huge diffrence.
mine was 2005. and i couldn't use this option on the AC. but on my friends 2004. i saw big diffrence between scanner and #8

Not sure where the AUTO button is coming in on this. On my 03, it's the Off/Rest button that you hold for a few secs. Try that doc and others that can't get it working.
No need to worry bout temp, that was on the W210.
