Auxiliary battery malfunction
#26
Warranty took care of the aux battery and I noticed the distronic plus system seem more "active" when turned on. It was able to sense the lane markers better and make faster lane corrections. Unfortunately, the eco autostop also works all the time now...

I just read through the owner's manual and this is what it says about the display message;
"The auxiliary battery for the automatic transmission is no longer being charged. Visit a qualified specialist workshop."
Is replacing the battery the fix, or could there be more to the error message?

The infotainment system seems to default to off when I started the car. Had my aux battery replaced today.

Replaced mine today and the Brake Hold feature is back. It was explained to me that the auxiliary battery's main purpose is to keep power to the electronic shifter in case the main batter dies. This way the shifter can be placed in neutral for towing.
That's why the owner's manual says ""The auxiliary battery for the automatic transmission is no longer being charged."
Thanks everyone for the help.
