If you read the posts in this thread, you will come to the conclusion that you'll need to replace the cam chain tensioners and more importantly, have check valves installed on the circuits feeding the tensioners. These tensioners are hydraulically-operated. When the engine is shut off, the circuits lose pressure. It takes a few seconds after re-starting the engine before the tensioners pump up again, hence the clatter.

I have the same problem with my 2013 ML350 and I talked to my buddy , he’s a Mercedes’ mechanic working for The dealer so he told me it’s the timing chain . Basically it’s the chain inside the engine that needs to
be replaced . That chain runs the whole engine. I hope that helped
