I have an issue with my 212 e350 nowadays. The car has been vibrating before and I was thinking to replace the mounts. but for the last 2 days, while I was driving the car, at certain gear and during slow acceleration, the car started to vibrate like crazy even the roof of the car made vibration noise. When the car reaches 2k rpm or rapid acceleration, it is fine, other gears also fine. The speed was usually 50mph.
I don't have any obd, but i didn't receive any faulty so far. Any suggestions? Maybe mounts? transmission, fluids?

Thank you all!
If you concerned about the motor mounts recommend popping the hood and put the vehicle in drive with brake on slightly rev it and see if it bounce, then put the vehicle in reverse and do the same. The key thing is make sure everything is safe first (ie. not going to hit anything, no people around the vehicle, etc.)
Other than that, as someone else mentioned just put the vehicle on the lift and visually inspect the motor mounts.

tire pressures,
4Matic service,
front wheel bearings,
unless it's engine misfirings,
It is not 4matic. By the way, during that vibration and noise, i also see that tachometer pointer moves up and down. If it gives any clues what the problem might be

ok... that sounds like its more powertrain related.
Your scanner will come in handy to see what's going on.

things is doesn't draw network maps at that price.
Do you think it could be misfire or transmission?
Will any regular obd can read the faults? Or are they reliable when it comes to issues like this? I have a friend with obd2, i can ask for him to lend it for a day to scan.

The best is to scan codes for sure but if you suspect spark plugs, that is a possibility.

A $50 generic OBD2 scanner is better than nothing for sure. It will read your engine faults.
Whatever is acting up to get your attention is a reminder someone needs to look after maintenance + repairs.
Many items don't survive being ignored long before snowballing into bigger jobs.
Review your record for scheduled fluids :
Engine oil 5w40 every 5kMi not 10K!!
Tranny ATF service
4Matic/Differential 75w90
MB anti-freeze coolant
Brakes DOT4
All these scheduled items also have associated repairs.

I checked the car with an OBD II scanner and no faults were found. I also put the car on handbrake and try again if i could replicate the issue while standing still. I didn't hear any vibrations. I will try again on highway and see if i can record a video.

no worries about the legs but just to be double sure get one of those Launch discussed. There might be MB specific codes that these generic scanners can't detect.
