I had this feature in my W204 AMGs and tried it on the my FL C63. No dice. Checked YT videos and as I thought, I was pushing the button but it just doesn't work. Windows sunroof down, hold the button, no movement. Any ideas?

This happened to my ML after disconnecting the battery. I reset/ normalized the windows & sunroof and it worked again.

...tunnel mode?

I didn’t know tunnel mode was available anywhere in the W204 chassis. Last I had it was a W203. Pressing and holding the recirculate button on the HVAC panel would close all windows//sunroof simultaneously.

Neat feature they should have kept. Couldn’t have cost much.

Yea, had in my W203 and looked on YT and saw the same feature. But those were for either pre-facelift W204s or non-AMG ones. I can't see why the AMG would be different, maybe a facelift thing, but it's not working on mine.

Ok, in my world, tunnel mode would be the exact opposite, I would like a tunnel button, it would open all the windows, open the sunroof and drop the transmission down a gear or 2 and then go full throttle!

I know you can do this when locking and unlocking the car (from outside), but this is the first time I've ever heard of a button doing this.

Agreed

I had a prefacelift and facelift W204 over the years and neither had tunnel mode. Only my W203. So I don't think this ever existed in the W204 (in the USA anyway).

Im suprised you guys didnt know about it. Mine doesn't have it, 2010.

Also when it rains, our windows are suppossed to close automatically, nope

Come on, you don't do this in every tunnel?
