W210 Mercedes - Vibrations
I have a W210 Mercedes facelift - E240 - V6.
Recently, the car is horribly vibrating while on neutral or while in idle.
The vibration occurs a few mins after the car is switched on. While driving there is no vibration and all is smooth.
Also, the engine feels like something is blocking it and heavy.
Upon accelarating, if the speed crosses 120 km speed, the ESP and BAS lights come up and the speed reduces.
If the engine is switched off and switched on, all is ok but the heavines in the engine is there.
The mechanic has checked all the spark plugs, coils and injectors. All have come out as good.
There is free flow of petrol.
We did not find any leakages anywhere. Coolant level is ok.
All filters were replaced about 1 year back with about 10000 km driven.
The engine mounts and gearbox mounts were also replaced recently.
My mechanic has found there is a oil leak in 2 cyclinders and wants to know if the issue could with the head block or if there could be something he is not able to identify.
Note: There is a drop in mileage and due to the heaviness in the engine, there is difficulty in gear shifts sometimes the gears shift from 1st to 2nd after 2000 rpm.
Can anyone please suggest a few troubleshooting steps and how to fix this issue.

lol I’ve been going down this rabbit hole on my CLK55 for last 4 years… closest I got after new everything was dumping valvoline import multi vehicle and just suck out and refill.. about 16 qts..(rather than maxlife atf or anything else) got her damn near perfect.. found a used diff.. threw that in and trans vibrations got worse!!! Then blew said diff.. threw old one in she was good! Figured I’d throw some more shudder fix in before my final suck out/refill.. just to see.. damn son! Back to square one… horrible shudder up and down through 35-45… weird thing is.. shudder cleaned up everywhere else.. shudder fix had originally cleaned up and got rid of the 19 mph 1-2 shudder..
so **** it.. 150 miles and 15 quarts or so new put thru… she’s driving perfectly smooth everywhere else… and almost negligible @ 41-44… Jesus I might put another 4-8 quarts thru before I do shift/lockup solenoid and new conductor plate.. can’t rule out differential 100% as I’m dealing with 2 ****bois I have and not sure I can even get a quaife.. which also happens to cost as much as 1 month for my 25 M2 with insurance. Don’t even drive it.. have too much fun driving this.. she roasts both tires on launches tho… got pulled over for it tonight actually.. “improper start” lol
