So, on the C43 the issue has been identified as a certain driving style during the break-in causing an incomplete initial adaptation cycle. They didn't specifically say what it is that causes it, but my personal hunch is that it's caused when owners don't stay in Comfort mode for the first 1000 miles, and use WOT too early. The issue first appeared on the press cars, which are driven by a bunch of journalists in less than an ideal way. I have not heard of this issue on the GT press cars. Also in case of the C43 it was the first time AMG paired this transmission with a non-V8. The MCT was specifically designed for the V8 engines, so I also suspect they left a few rough edges making it work with a smaller less torquey 4 cylinder. I'll repeat it again, stick to the break-in instructions as laid out in the owner's manual and the sticker in the windshield. Don't start using Sport and higher modes, use only partial throttle and stay below the specified rpms, and don't do manual shifting before completing the break-in.

I wonder if MB should had limited the RPM and specific break-in guidelines through software so people have to follow the break-in as the computer won't let the car go beyond the conditions set prior to break-in being completed. I see some form of this in place for example race start not possible but is it too dangerous if say they limit the engine to only 4K RPM through software until break-in is done, say for passing or get out of a dangerous situation?

No, just not properly adapted. Best approach if OP indeed didn't follow the break-in instruction would be to reset the adaptations and then follow the break-in instructions for the next 1000 miles. Basically do it over.
That would be a liability in case of an emergency.

I thought so.

[QUOTE=superswiss;9173492]W przypadku C43 problem został zidentyfikowany jako pewien styl jazdy podczas docierania, powodujący niepełny cykl adaptacji początkowej. Nie podano konkretnej przyczyny, ale moim zdaniem wynika ona z faktu, że właściciele nie pozostają w trybie Comfort przez pierwsze 1000 mil i zbyt wcześnie włączają tryb WOT. Problem pojawił się po raz pierwszy w samochodach prezentowanych przez dziennikarzy, którymi jeździ wielu dziennikarzy w sposób daleki od ideału. Nie słyszałem o tym problemie w samochodach prezentowanych przez GT. Również w przypadku C43 był to pierwszy raz, kiedy AMG połączyło tę skrzynię biegów z silnikiem innym niż V8. Skrzynia biegów MCT została zaprojektowana specjalnie do silników V8, więc podejrzewam, że pozostawiono kilka niedociągnięć, aby mogła współpracować z mniejszym, mniej dynamicznym silnikiem czterocylindrowym. Powtórzę to jeszcze raz: trzymaj się instrukcji docierania zawartych w instrukcji obsługi i na naklejce na przedniej szybie. Nie należy zaczynać od trybu Sport ani wyższego, należy używać tylko częściowego otwarcia przepustnicy i utrzymywać silnik poniżej określonych obrotów na minutę, a przed zakończeniem docierania nie należy zmieniać biegów ręcznie.[/QUOTE
]After driving about 4,500 km in my AMG GT 63 Coupe, the transmission started jerking.
The car was unbearable to drive in traffic. I've already had the second update and adaptation done at the service center. It helped for 5 minutes.
The service center told me that many models have this problem.
