New C63 Valve problem
I bought a brand new C63 Amg a month ago i only have 2k miles on the car and i am having this dumb annoying issue with the valve staying open or making a noise when the car is in auto off and on mode. It makes a PEEP NOISE. Almost like a squeaky door noise but more high pitched. Took it to the dealer they said the valve was staying half open and they fixed it. They even said their is a TSB on it (stale face) anyone else having this issue?

I had something similar.
does it squeak if you just barely tap the throttle? If so my dealer said the h valve needed to be greased. They said it’s very common apparently they don’t get enough attention during original build. Haven’t had issue since.

Yes but mostly when the car goes from off and on from the comfort saving gas mode. They said they performed the repairs on the exhaust.Drove the vehicle for the weekend and boom here we have the noise again. At this point i dont want to get in a back and forth with the dealer I am going to drop it off to them until every single thing is fixed on the car
