In the S CLASS W220, does anyone know what the menu is when you hold REST and RECYCLE buttons that bring up the following logo /-/ and only goes up to N14.00

It shows ...........aus and zu in 12 and 13. Aus is German for from, and zu is German for to

Then there is an option to increase the percentage of something.........possibly aircon settings ??

From what I can see, the W220 has an engineering menu by pressing both AUTO buttons, set both temps to 22c then press REST then you can scroll through each value by pressing the left temp +
left hand is the number, right hand is the value

1 in car temp sensor temp
2 outside temp sensor temp
3 leaft heat exchanger temp
4 right heat exchanger temp
5 evap temp
6 coolent temp
7 refrigerent pressure bar
8 refrigerent temp
11 left duo valve %
12 right duo valve %
21 engine rpm
22 vehicle speed

This is another menu, specifically.........press and hold REST and RECYCLE buttons that bring up the following logo /-/ and only goes up to N14.00

Another menu is available by holding REST only button for a few seconds

This comes up on my W215 too. You can select each of the parameters from the left side temperature control and adjust their values, OPEN or CLOSED, from the right. Still don't know what any of them mean...

I think all of the digital air controllers are activated the same way, some have more detailed information than others

I have seen these menus in the 202 with the self check, the instrument clusters also have a self check on the 129 and 140 I will spend some more time when I can and maybe do a sticky post about them all
