Engine run-in (break in period) beyond 1,000 miles
I have owned my 2021 C63S cabrio for around 4 months. I do enjoy the car, I just don't do a lot of driving right now, thus my car is still in the break in period having just under 800 miles. I have been careful keeping the RPM's at or under 4,500. As I approach 1,000 miles, are there any restrictions as far as maximum RPM's after hitting 1,000 miles? I doubt I will be using launch mode for some time to come. I have been using the different performance settings while driving including S+ but only to check out handling characteristics. It seems I remember seeing additional break in procedures even past the 1,000 miles?????? Any input would be appreciated!

I remember talking to one of the amg guys at amg track driving event. He said after 1k miles then increase your rpm every 100 miles. Make sure you do an oil change plus differential. Then another oil change after 2k miles. I change mine every 5k miles
Last point in the breaking-in notes. You are supposed to gradually increase engine speed after 1000 miles. Don't just go WOT the moment you hit 1000 miles. Unscheduled oil changes are unnecessary. There's no break-in oil in these engines. The rear differential oil change is also no longer necessary unless stated on the window sticker.

ya seems like according to mercedes the break in period for the later year W205s is a little different than the early year W205s. the differential change is not needed anymore.
I purchased my 2019 C63S coupe in early April 2019, it had the window sticker regarding the Break In Period and the Differential Oil change at 1,875 miles. (Photos below). I was also informed by Tech Advisor at that time to have the rear Differential Oil changed at 1,875 miles. The Invoice parts and labor was $278.05 with tax.
As for the recommended Break In Period of 1,000 miles? but I felt it took over 4,000 miles to where the performance and handling greatly improved. Now as I approach 17,000 miles the car is a dream to drive
