ML63 break in...
That being said the ECU records rpm, temp, etc so not following the break-in could potentially void your warranty.
There are also other things, transmission ,differentials, tires etc. that do require some break-in for optimal performance and durability.
On my visits to AMG and the engine facility I have never been told that there is no break-in needed.
With Porsche that is not the case, run them hard they claim....
Go for some fun short and long kinda boring rides holding back as best you can and break-in will be over in no time.
