Hi everyone,
I’m in need of some guidance. The car has been with Mercedes for the issue of the right valve not opening and the car sounding like a fan as well as the right tailpipe and housing not getting warm. 4days later they replaced the valve and motor but the issue is now worse. I’ve attached a video, hopefully someone has had this and knows the fix.
Ps video is sound in drive, sport plus
