2016 C63 not getting boost
So I was driving on the highway then noticed that I wasn’t getting any boost. I have brought it into the dealer 2 times because of misfires and flashing check engine light. Which caused the car to go into limp mode twice. I’m bringing it in today again to have it looked at for loss of boost and loss of power. I have had the car since November and am thinking of returning it now because it hasn’t even been 3 months and have brought it back 3 times including today. Its only has 35k miles I bought it with 34k miles. What do you guys think ? Thanks (video in the link below)

Ignition coils need replacement it's under Mercedes campaign for replacement.
Affected vehicles are 2015-2016
Also a campaign for pinched waste gate actuator hose , hence for no boost pressure.
Obviously the dealer your dealing with is very lacking in its ability to correct the problems.
Go some we're else.

Most likely one of those two issues.

First time I brought it in they changed 4 spark plugs, 2 ignition coils and a week after I got it back the check engine light flashed again & car went into limp mode shaking. I brought it back and they said they fixed it got it again & now I’m not getting boost so I called they said bring it in. Mind you this is a Mercedes dealer.

I also had coils replaced at another time but not associated with the boost issue.
