It sounds like a sticking A/C flap servo motor, or the linkage is broken. It's a fairly common problem. It should be covered under warranty.

ah.. I forgot to say that it only happy when I press on the gas?! so weird... I guess I have to find time and go to the dealer thx alot for the info!

don't worry, its just a timed device that will detonate once the car is out of warranty. Mercedes does this to generate service revenue.

Hello Blueice,
It sounds familier to me. Search this forum.
And yes, it happened when pressed.
