Vibration under load @ low RPM HELP

2017 C63s Coupe. Today for the second time since owning the car I received the “ELECTRONIC REAR DIFFERENTIAL LOCK INOPERATIVE “ message. Not sure if it was coincidence or not but on the way home once car was at normal temp I could feel a vibration in the drive train under load and low rpm. No matter what gear or dynamic setting. Anything over 3-3500 rpm I couldn’t really feel it. Car has 24k miles on it. Any help appreciated before I dump a bunch of money at the dealership.

Awhile back, I would always receive that message anytime going over 10 mph but I was still under warranty so I brought it in. After a software update, never seen that message again. Around the Dallas Fort Worth area, it would cost 180$ if your not under warranty. There are other threads about this issue and majority was solved with the software update.
