Hi all I picked up my w212/c207 2014 E400 (3.0) and I noticed a rattle on cold start and under acceleration I took it back to Mercedes as they was supposed to have checked all this among other issues and the tldr was that there no errors so there is no problem but I worked on cars for a chunk of my life and to me it does not sound right at all. It sounds like it's coming from the back of the engine/underneath. I recorded a video although it's not very loud on video but it's is there. The noise starts in the video at around 6 seconds in. If anyone can shine a light on what it could be would be appreciated.
