This is a well known feature. I've found some keys to the codes (i.e. what parameter is being displayed) but I've never found anyone, even MB technicians who have a complete list of what they all mean. Also, as far as I am aware, this is only a display/repeater, you can not modify any settings or give any commands through this function.

Hey guys, this hidden menu is used to check all the fault codes in your ac system, and also allows you to erase them which in turn unlocks the ac compressor if youve ever ran out of freon. Just did this last week to refill the freon and it was a great, dealers were trying to charge me to reset with star diag, but i did it myself

Hey there Eric,

Despite the snide response, thanks for your input, but I think you misunderstand. I am not talking about the AC diagnostic function which can also be activated by the REST button. I'm talking about the 90 or so parameters displayed otherwise, by just holding it down for a few seconds and using the temp arrows to scroll through it. If I recall correctly each separate parameter is labeled V1, V2, V3, etc.... I'm not the only one who has not been able to find the definitions of these parameters. See, for example, here:

http://www.benzworld.org/forums/w220-s-class/1379706-there-key-information-displayed-through-rest.html

Now, if you're aware of somewhere that has these that I've missed through my "laziness" I'd be much indebted to you to point it out such a location.

Best regards,

LR

All... Many thanks for responding...but... I am NOT referring to the following:

* REST button (Pressed ) alone to review the NXX. details
* REST + Carbon Filter Button (Pressed) for Aircon Diagnostics and reset.

I am referring to the REST and RECYCLE button that brings up the following logo /*/ (but horizontal) and only goes up to N14.00, Eric perhaps you can shed some light on this query?

Many thanks for the replies.

I sure can, but I would need to read the appropriate section on WIS first, maybe in the morning as I am at home now. The thing is I always use DAS so I have never bothered with the on-board diagnostics, but I do have access to that info, will let you know.

I just had a look at that menu....new one on me:confused:

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 ??

Hi all,

Does anybody know if there is any hidden menus on W220 that can display the information on how full the dpf is clogged up?

Any information is much appreciated.

Thanks,

David.

No airco on the right side

Hi all,

My problem is that on the right side (drivers side) i have no airco. I have air but no airco. When i put on both sides LO and on the top blower on blue you can feel a differance of +/- 5 degrees Celcius between the right side and the left side.

As far as i've been reading on this site i think the temerature sensors are all working.

Anybody got any idea what the problem might be???

Thanks in advance,

Bori$

BTW: S430 (W220) - 1999 NL
