Does anyone have a complete list of the AC Diagnostic Values? I have the basic ones that go up to 20 or so, but I know on my 04 E55 it goes up to 99 with a few gaps in there.

Thanks

 

Hi,

I have the 4 zone climate control on my 2004 w211 e500, i tried many combinations to get the diagnostics (including holding the rest button for 5-10 seconds) on my ac but havent succeeded. is there any way to get diagnostics on the ac digital display.

here is a link for codes: http://www.bba-reman.com/content.asp...on_fault_codes

Thanks

 

On mine I have to hold the AC OFF button and it comes up. On my w210 its the AC Rest button. I'm looking for something that list what each value is once you have the Display in Diagnostic Mode.
