Pretty sure thats the chain tensioners. Earlier models of the W212 had this problem. Not sure how specific this is to the OM651, but I know it is atleast present in the M276 (I believe M278 aswell)

Definitely something that requires oil pressure to pump it up. I'm with DeTh

I have had the same issue, IMHO it's just annoying and usually lasts only a few seconds.
When the dealer replaced chain tensioner in the process of AEM it went away.
