Valve issues C63S 2015
And when I'm in sport+ and the valves are open, they close when I'm at a red light. As soon as i release the brake it opens. When stationery I can play with the valves pressing and releasing the brakes
Had a non dealer mechanic look at it and with the computer he could open and close (you could clearly hear the difference) so the valves work but not the way I'd like or thought it works. Maybe its the standard for the first yearmodel
Would love some insight on the matter

If you do, then there's an issue here. Pressing the exhaust button on your console will open the two rear muffler valves regardless of which mode it's in. I always drive in Comfort mode with the valves open.
Does the exhaust button on your console illuminate red when you press it (like in the picture below)?

The button illuminate when I change modes, but in comfort it dos not illuminate when I press it




Has yours always done this? How long have you had the car for?
I can put mine in LOUD in COMFORT mode even with ECO on. Did this suddenly just happen? Or always been like this?

but I turned to this forum first so

I was thinking a way to test it. Can I in individual set everything in comfort expect the valves? I mean just to test it?
