Bad motor mounts?
I have a 2008 C300 4Matic with a vibration at idle. It’s not all the time, but most of the time. I have a thread from a while ago on this where I went through a bunch of issues and a lot of you helped me eliminate most of it, but I’m stumped on if my engine mounts are bad or not. I did jack up the engine and the vibration when shifting was removed, but I understand that could still be from other problems as well.
I took this video where I shifted through all the gears, gave it some acceleration to roughly 3500 RPM, engine is warm as well. I see nothing wrong that indicates engine mounts, but my symptoms still present as engine mounts. Any ideas?
Heres the video:

Nope, just didn’t think it was relevant too much. 179k miles on original engine and transmission, unknown maintenance history but visually the engine mounts are fine as well. No obvious cracks or anything.
I’ve done a **** ton of maintenance to it in the last two months I’ve had it, and minus the vibrations I’ve had no issues.
