By the way guys, there is a chance, that the exhaust flaps are not binding, instead the exhaust valve fuse is blowing time to time. Thats what happened to my Performance exhaust, they just replaced the fuse. Took them a while to find it. It makes absolutely no sense for brand new valves to bind unless you guys can explain why it is happening.

A couple months ago I noticed that my sports mode exhaust light would not show sometimes.
This week I took my car in for service and mentioned it
they changed out the button, no fix, and next the exhaust valve which I’m guessing might mean they put in s new exhaust from what I’m reading here
car sounds louder now

On my 2016 GT S I have noticed when I active sport mode for the exhaust, the red light illuminates as it should, but after driving for a while the light will go out. Pressing the button after this happens will not re-illuminate the light. The command system does indicate the modes are changing on button presses. Turning the car off and back on seems to correct the issue for a short period of time just not sure if there is an issue with the valves themselves when this happens.
Any one else had this issue?
Also, has anyone had issues with the hood struts? I raised my hood to the 90 degree position and the passenger strut seems to be seized. Had to remove the strut entirely.

I have had this same issue with my 2018 GTC. After I drive the car for over 20 minutes the exhaust button would not stay on in race or sports plus mode. I took it to the dealership and the replaced the actuator. The problem got better but time to time it still does not work. I found a way to get it back on my turning off the car on and off multiple times. The dealership was trying to say that the issue is coming up because i did a secondary cat delete. But in all actuality this problem occurred way before that.
my car has 16k km, and the problem arose awhile back.

Quick Update:
Took the car to the dealer and when I dropped it off I spoke to the tech and he mention there was a service bulletin for the exhaust issue. Got a call at the end of the day saying there was a code stored for the exhaust valves and per the bulletin they updated the software. After the software update, they were unable to re-produce the issue. The service adviser said the car was ready to go and if it happened again they would need to open up a PTSS case.
I picked the car up and on the way home, the exhaust light went off again...I called the SA and put the wheels in motion for the next steps.
I'm not familiar with the PTSS process any suggestions? She mentioned they would need to keep the car for a week.

PTSS is 'Product Technical Support System', it's escalating a concern to engineering/AMG for more info.
In this case, there are bulletins about lubricating the shaft/motor of the exhaust drive and other ways to look into fixing it, so the PTSS case is a bit premature. You will most likely end up with a whole new exhaust if you continue to have issues.

What is aggravating is when you let them know the issue you are having along with the details and the response is like it is the first time they are hearing about this issue and maaaybeee they can recreate it and sort it out.... and then you find out after by reading other owners posts online that is a known issue and there is no way they don't know.
It's annoying, and disengeniuous to some extent imo.
It's happened to me both for the loose seat and the exhaust. And it's the only thing I dislike about the dealership I use. Everything else about that place is 10/10.

Did they at least give u a good loaner while they kept your car for a week?
Also did they tell u why they needed your car to sit there for a week to install a rear exhaust??

No dealer that I'm aware of keeps that exhaust in stock.

Came with my car. Mine was in the rear fuse location, under the cover. Not sure if the previous owner put it there, or if that's where they stick it from the factory.

Is the 'Küster' exhaust flapper the correct size for a BS?
