recirculate button doesn't close moonroof?
after reading about using the recirculate button to open/close all windows, i tried it out. but it seems that the moonroof is not operable that way. am i doing something wrong? is it only this way for the coupes?

Young, you have a C230, right? I don't think the C230 has a "one-touch" close for the sunroof, right? When you hold the recirc button for 2 seconds, it activates the one-touch close function of all the windows and sunroof (on the C240/320). That's why you can let go of the button after the all-close starts, because each of the windows and roof "takes over" w/ its local one-touch. So, if I'm right about the C230 roof, that's why it won't close w/ the windows. (Sorry...)

One more thing about the open function...
You can't use the recirc button to open everything when you first get in. What it will do is this: if you use the recirc to close everything (supposedly when entering a tunnel, or such), if you haven't shut off the engine, you can later press the recirc again for 2 seconds and it will return the windows (and roof on the sedan) to their positions prior to the close. I tried this, and it will not remember the settings once you shut off the car. I usually use the recirc button only to close everything when I'm ready to shut down, then I press it again quickly (less than 2 secs) before I turn the car off to cancel the recirc mode.

(the world's second loudest/longest) DOOOOH! 
i thought that that may be the issue. actually, i really hadn't tested the smart key open all/close all feature either. i wonder if the close all has similar issues. only one way to find out...

well, i just tried out the smart key open/close all and it works including the moonroof. (albeit, i think its a bit tricky - had to hold the key just right).
i wonder if its a programming issue?
it doesn't really bother me if its missing. just sort of curious about it.

Young...
I would consult your manual first (not trying to be a smartass, but just to see what it says.) If it suggests the recirc should close the sunroof, then I would put it on my list for the dealer to investigate. Because...
The recirc on my sedan closes everything... BUT the right rear window. Hum? Also, if the sunroof is open (retracted), the recirc will close it, but if the sunroof is tilted up, instead, recirc will NOT close it (tilt close). These are issues on my fix list.
Point is, recirc appears to work on MOST of my glass, but not all, just like yours. I imagine there's a board that needs diagnosing and replacement.

darn it, mb-bob! now i gotta go back down to the garage for the manual... 
didn't think it would be a defect. i'll check.
- 5 minutes pass -
the manual states that only the power windows will go up/down w/ the recirc. button. so it works as its supposed to. i should read the manual more.

Guys, if the C230 doesn't have one-touch close for the roof via the sunroof switch, the recirc function won't work because it activates the one-touch feature of all the windows and the roof (on the sedan). If the roof does not have one-touch close via the sunroof control switch, there's nothing to be fixed. If you're not sure, open your sunroof and then press firmly on the switch to close the roof. If it doesn't "click" like the window buttons, there is no one-touch close (I think I read this before -- it only has one-touch open).
MB-BOB, that happened with my left rear window once. Check the owner's manual for re-syncing the windows. I think you open and close it and hold the switch in the close position for 4 seconds (something like that). Once I re-synced the one window, it worked fine again. You will see that that particular window also will not go up if you activate the "one-touch" via the driver switch for that window. Even if you pull the switch to the "second" position, the window will refuse to close all the way until you re-sync it. That's how I realized that the recirc button simply activates the one-touch for each window and roof.

Sorry, Dude...
... just suggesting not to give up so easily. These really are complicated cars. I just hope the error code system will easily diagnose the probs (once you bring it to attention). They sure won't check unless you ask.

Closeing the sunroof and windows are part of the tunnel feature. It only works on car with the micro filter switch on the ac controls.
The c230 k does not have this feature.

Also, if you use the smartkey remote to close everything, the reason you have to hold the button in that case is because it does not use the one-touch close feature for the windows and roof. It just operates as though you were holding the control switches for each of the windows and roof.
Renncpe, try it on your C230. Open the windows, then press and hold "recirc" for at least 2 seconds. You can release the button as soon as the windows begin closing. You will see that they then close as though you activated the one-touch close on the individual window switches.
