I gave up at this point.
New MB engine mounts, Trans mount,
New spark plugs and filters
TB cleaned.
Not all the times, but half the times in DRIVE when stopped I get a buzz through steering wheel.
Also a light harmonic vibration when revving in neutral between 1500-2000, very slight.
Few mechanics told me I am nuts and its an old car. MB shops by the way.
I have yet to find a shop with star that can check if one of the coils is weak. Or TQ is tired.

Forgot to add, when car was in the air I felt the vibration in mufflers but the vibrations weren’t felt inside the cabin until wheels touched the ground again.

MY MYSTERY IS SOLVED
Happy to finally announce I have solved my dang vibration. When I tell ya I’ve done everything believe me. Almost freaking changed the torque converter too cause there was nothing left to change. My issue was axles 🙃 they were replaced with aftermarket axles. Pulled Mercedes OEM axles from junkyard and replaced my aftermarket’s. Night and day difference 98% vibration is gone!! Might not be everyone else’s issue but if you’ve put on after market axles I’d look into it.

WOW
Hi. I have solved this 4matic front driveshaft related vibration at idle mystery. Vibration occurs in D and R when you hold the break. Cause is inner cv-joint, witch is assembled wrong in cv-boot repair or similar job. There is 3 rollers witch can be assembled both ways. If those are wrong way around, they are jamming and engine vibration transfers dirrectly to front wheel and then the whole car. Right way is the lock washer outwards.
This thread put me in the right track when I troubleshooting my customers car. Thank you all, and greetings from Finland!
