2019 CLS450 4 Matic 2011 E550
Command problem

I'm having an issue with my 2019 450 4 matic. The radio display goes out on me. Sometimes it will work if the car is restarted. Next the I notice it always shows partially charged. It has the original battery in it. If I have to replace it is 5hete any coding that has to be done or just buy one and pop it in? Any help would be appreciated.

In xentry there is a step to reset the battery counter, i usually do that after the 12v battery change. Best to check with the shop if they have xentry or suitable diagnostic tool to perform the battery reset.
