[Solved] MB W212 converter ??? - Vibration while driving, wave rotation, jerking ....?

Hello, I imported a car from Germany ... Mercedes W212 e350. AUTOMATIC 2011 ... Mileage 250,000km
The whole car without an accident, however, I bought it as out of order.
The German described that the car tugs and vibrates while driving, indicates a malfunction of the engine or gearbox ...?
He said that the cost of such repair in Germany would be comparable with the value of the car and decided to get rid of it ...
Indeed, the whole car shook after firing !!! At first glance, the replacement of all three pillows went! -
Engine mounts on the w212 and w204 had a factory defect and owners of these cars were often called for warranty replacements ...
After the exchange, the shaking at a standstill disappeared!
I connected the car to a Delphi computer that showed no errors !!! THREAD!!!
Normally he should "throw out the error of the box sensors -" mechatronics "something with the engine and nothing !!!
So on the road ... The car started even after "driving D" to the moment it started 1.5s to 2s - a bit long !?
First gear, second, third ... threw in nicely, also dumped until the car reaches a constant speed in the 12000-1500obr range on 4-5-6-7 gear, or how hard it is, and then it starts!
When adding gas slowly by car tugs - something can be heard - a deaf rumble similar to a damaged wrist.
It subsides after reaching 2000obr! or when I release the gas and I will add temporary peace again!
With dynamic driving at high speed "there is almost everything" ok. Jerking is hardly noticeable ...!
In addition to jerking, I also noticed wave revolutions within 150 revolutions, which are often accompanied by cyclical vibrations (something like approaching an emergency lane on a highway). These vibrations spread throughout the body - everything shakes and stops over and over again ....
On MB Service - I have already received information about repairs and replacements in Germany in our country!
No mention of oil change in the box !!!
So I went to the oil change to one of the reputable companies dealing in "vending machines".
The reaction to the symptoms I described to them was "quite strange" and they said "we will see what happens after the oil change"!
As it turned out, the oil was not changed from the news, what was worse was missing in the box about 1 liter of oil.
After the oil change, there was "some" improvement ...
The box smoothly throws and drops gears. The start of the first race is still late !!!! Unfortunately, jerking at a speed of 1200-1500 left!
The cyclicity of vibrations has changed - the time from vibrations to vibrations has significantly increased and occurs on average every 5km, which is interesting, vibrations also appear on the so-called "jumps" on a straight uneven road!

Has any of the honorable mechanics encountered such a problem?
Any suggestions?
No errors on the computer !!!
Shaft, support like new!
Engine OK ..
Thanks for the help!

Such vibrations accompany the worn converter.
But if the oil has not been changed from the beginning, the current change may not help you anymore. the point is that the impurities in the old oil may have already accelerated the wear of the elements.
If the reaction to D lasts noticeably longer than this second. this could mean wear on clutch cage piston seals or valves.
Probably the previous owner too often switched to N or P, e.g. when stopping at traffic lights. This should be avoided.

Thank you very much for any and even more substantive answer !!!

Are these elements such as: Sealing of clutch cage pistons - the elements located in the converter?
Valve sealing - mechatronic?
After the oil change I drove from 500km!
These vibrations ceased! However, it still "swings" the car under load at low speed!
Gearbox changes smoothly ...
But with a start from 0 km there is a noticeable problem !!!!
I'm going to dismantle the crates.
The converter plans to give back for regeneration - I found a company from Lublin - the cost is not great, up to PLN 850 from GW.
In addition, I wonder if disassembling the "mechatronics" and cleaning the valves will help?
Oil change has helped, but that's not it ....
I have a "good mechanic" who can fix basic problems in ASB
but if you have to replace the seals inside the box, you may have a problem and is there any point in doing so
Is it better to look for a stimulant?

And one last question ..
If the converter is worn, can it have an impact on delayed start from "0" km?

Hello!
these seals I wrote about are inside the box. Not in the converter.
A worn converter causes vibrations at e.g. 1500-2500 rpm with, say, medium load. But it can also cause a muddy start.
And the vibrations you're writing about now, and maybe replace the candles with new ones. If the engine begins to lose ignition under load, you will also feel such specific jerking. Well, it should be the error of falling out, but you know how it is with all this: /
Returning to the chest. What did the start oil look like? Was it raspberry-red or black with a suspension?
If black, then if the box is already out of the car, maybe rather do a full renovation. Especially if you do it for yourself. This one does not seem to be a tragedy. And with stimulants it can be worse.

Hi.
The color of the oil was, let's say - dark burgundy falling into black - thick!
As for the so-called filings, there were no bowls on the magnet, while the standard "light goo" on the magnet was visible!
About 1.5-2mm thick
I changed oil with filters in Wroclaw in one of the more reputable companies. The cost is PLN 650.
I received registration frames with their advertisement for free from them
According to the mechanics who changed the oil, it was not a tragedy but not too colorful!
They said that the oil was certainly not changed from the news!
After the exchange, they told them to drive a few kilometers minimum 100 and "see what will happen ..."
I got the impression that in the described company, the answer to each question has a price.
They also stated that with such oil condition and mileage, the so-called "dynamic oil change" could be carried out, but it cost PLN 1800
According to them, the symptoms described do not necessarily indicate damage to the chest (all the more so that there are no errors on the computer)?
But .... If I want to get information about the condition of the box and possible damages and faults then I heard:
"Inspecting the crate and identifying the fault costs PLN 300 ... without guarantee that we will find something"
"converter replacement - (converter regenerated only by them), exchange with them - PLN 2,600"
"Thank you, welcome again"
The problem is getting to them 130km one way, leaving the car for two, three days and the next journey ....

Prices that I would have at my place are: regeneration of the converter with shipping to Lublin 825 PLN, oil with Febi filters 280 PLN, the cost of replacement with cleaning "mechatronics" 400 PLN. The repair time depends on the shipment, repair and returning the converter from Lublin ...
The car stands at the mechanic, whom I "trust" and see what he does with the car!

A week ago I was also at one of the auto-electronics who had a W211 7G workshop with a broken converter and no errors.
Has Star Diagnosis ... According to him, my turnover at 1500-1800 rpm rises in the range of 150-200 rpm.
W211, which was diagnosed waved revolutions while driving at 1500-2000rpm in the range of 1500rpm. You couldn't go ...
He told me that this W211 was given to "Mr. Staś handyman" - he mentioned the converter, oil, filters!
The car after the exchange was like new! - unfortunately only for 3500km and then returned to the state from before repair ....
Now the car is standing and the owner has no more strength for it!

I'm slowly getting ready to replace the converter ...!
I will do another 500km so that the system is well flushed with new oil and mixed with the rest of the old oil, which always remains ....

Does the regeneration of the converter look similar to the regeneration of a dual-mass wheel?
In most cases, on a regenerated "two-mass" it will be possible to travel from 20 to 35 thousand km - 60,000 km with great luck.
On the new e.g. Sachs, Valeo 180-250 thousand km ...

And one more question what converter element causes "muddy" delayed start from "0km"
I watched the visualizations of the converter work on Youtube and it is hard for me to find such an element.
There is one that locks and opens properly but is that it?
- are Mercedes 7G converters differently constructed than the standards shown in the visualization?
Thank you for your answer. best regards

I've already done 3000km since changing the oil!
Shock! - from the last 700km the car began to perform better day by day, until the described jerks and vibrations ceased !!!!!!!!!!!!!
What was left of the symptoms ???
The impression of a late start is first.
Secondly ... Freshly fired on a cold engine after reversing - there is a feeling as if the clutch too tight or too slack.
It once happened that the Austo went out when leaving the parking lot (here zero errors)
When the car heats up everything is ok!
I will make another exchange and write what and how ..

And how was the car?
Is he still trembling?

Added after 4 [minutes]:

For me on a cold engine, trembling on reverse is very noticeable at N much less.
Immediately after driving off, when I reach the roundabout and the speed drops, the whole shack swaying as if I was driving on corrugated asphalt.
The hot engine is ok

Hello.
I am struggling with a similar problem in the Chrysler 300c 3.5, I have exactly the same symptoms after changing the oil in the box, I will add twice. Twice because after the first exchange of the cradle, it began to jerk when shifting gears and sometimes gently vibrated, so that it was felt all over the car, led to the mechanic again, rinsed the crates, flooded again with new oil for this conditioner and now there is a tragedy, exactly as described by maxbike1. ... Errors on the zero box, I also got it at a professional who only overwhelms an American, the previous mechanic tells me to do some kilometers on this oil and wait for a week, I have done 400 km and a week and I would say nothing and maybe even worse,
Question to maxbike 1, after driving how many km you noticed an improvement ???

Solution! The chest is OK ... !!!!
1. Purchase and replacement of two new engine cushions!
2. Purchase of two new rear cushions.
3. Replacement of exhaust gas temperature sensor before turbine!
(defective sensor causes the car to enter the state of burning dpf.
The car at high speed gives faulty information to the box and it happens that the car sometimes jerks on the box)
