If you have a failing mass air flow sensor this can act up after a bit of time of running as I have seen before on this model here and can send an incorrect air flow reading signal and cause this issue here.I had a problem one of these S classes around this year that did the same thing and spent weeks trying to locate the fault and then swapped in a new mass air flow sensor as I was out of ideas and it corrected the fault here.
