If you have someone with a STAR / Das machine they can reset self-adaptation mixture, not only delete de error. I will start with that first and see what happens.
You can check o rigs / injectors on that bank, also a faulty lambda sensor. I had one and only after 3 months the error finally appear on the diagnostic.

I am not sure about the translation in your picture but it seems like this message is saying "too rich". The only things I can think that might cause that are a malfunctioning MAF or "fuel pressure too high".

The fuel pressure regulator is built into the fuel filter, if it's due for replacement, go ahead and replace it proactively.

A too rich condition can cause damage to your CAT - is your Check Engine light blinking?

Guessing as to the problem can get expensive. You will be best served to find an independent shop or dealer that has the MB DAS (Diagnostic Assistance System) to connect to the car. It will provide you with much more information than the more generic code readers and may well tell you exactly what is causing the codes you have. I would consider any other steps a waste of time and money at this point.

Dear All
Update... I change also coils (6 of course) problem same... but my "specialist" said that before different errors.. should be right?
I don't Know... today he said that the problem is in catalizer...shall be clean, how? he suggest to use the car at high speed for 100/200 km, and don't care about the error.
This is the last change, Anyway with my interface OBDII wi fi I red the below error code (my self by obd check software)
P2188 , P2190, P0750, P0746. May be someone in the forum can give to more details about solution, using alldatadiy.com as per database.
thank you in advance.

Dear All, the problem is SOLVED
I went in MB, after 10 days of check , re-check, run test (they used the car for more than 350 km) some parts changed (spark plug, injector, air mass flow valve, air mass sensor, fuel system cleaning , injector nozzle, control unit program, gaskets, ...)
I cannot identified which of spare parts solved the problem, because MB have a sequence of instructions, and step by step they go on, and using also temporary spare parts that they used for test.
Anyway the is more 'drivable" soft, in particular during the deceleration, is different car now.
My suggestion is to give the car to qualified people.. of course you will pay more but when you will open the roof you will forget everything.
For any question full free to contact me any time.
The thread can be closed.
Thank-you to everybody
