What’s up everyone. I just bought a 2013 C250 Sport. It only has 50k miles on it and is CLEAN.

But…I’ve noticed some vibration coming from the engine bay. It idles smooth and there’s no knocking or anything, but when I looked under the hood it was shaking like crazy.

I attached a video I took but it looks like it’s on slow motion compared to the rapid vibration that is actually happening. Any ideas about what this is?

this is my 1st Benz by the way, so be gentle 😅
