I drive a 2016 E350 4matic and would like to get the code (which buttons to push) to enter Engineering Mode. After many previous MBs, I truly believe this system sounds the most anemic. Thank you for any help.

Thanks. I gave that a try but nothing happens. I must say that this COMAND systems looks different than others in the past.

I did come across a DEALER SERVICE menu...hang up/7/9. Doesnt do much tho. I hope there is a fix. Harmon Kardon would be upset if they heard the poor performance I am listening to right now. SMH
