2016 CLS550 4matic

Hi all,

Im new to the benz machine but better late than never. I have had a few glitches in my ride that have puzzled me to no end. First I keep hearing sounds long after the car is shut off. Most of the time its a clicking over and over coming from the fuse box under the hood. Next I fired up yesterday and now I get the AUX batt malfuncton. I replaced the main batt a last month as it was dead as a door nail. I went to batt plus and got a replacement and a friend said you should have gone to MB for that. I said MB wants $400 for a batt is it really that serious?? I will have to get that aux batt from them though.

I think something is not shutting down and it drains my battery but be damn If I know what it is. Scanner not telling me jack on that issue.
