Battery disconnect if car stands for a long time
Hallo,
I will be traveling for business over a period of 5 weeks and will leave my car at a park and ride station. Do I need to disconnect the battery or are there other solutions.
Thank you

You should activate the standby mode in the COMAND system. Not sure what year you have and if you have COMAND, but at least the 2019+ have a standby mode. It turns everything off, including the online services so the battery doesn't drain. If you have COMAND, mBrace or Mercedes Me connect are essentially constantly active and maintain a connection so that you can get status information from the car and do things like lock/unlock remotely. That will eventually drain the battery. After about 3 weeks I start getting battery critical warnings for my C63S through the Mercedes Me app if I don't turn on standby mode. I was traveling for 9 weeks earlier last year when I still had my previous car, an Audi RS5 and I hooked it up to a battery tender, just to make sure the battery doesn't go bad while I'm away.
I would also properly inflate your tires, preferably to max load recommended pressure, so that you don't get flat spots from the tires not moving for 5 weeks. Should be OK, though. I've been away for 4 weeks in the past w/o doing anything special to my cars and there were no issues.

I can start my car from anywhere in the world as long as my phone can connect to the internet using the ME app (that is when it works) It will automatically turn itself off after 10 minutes OR you can leave it with a trusted friend and (briefly) show him all the unique car tracking functions of the app, like the car log which shows when its been started, where its currently at, where it's been and how fast it's been driven. (My kid hates that I told him this...Bueller?...Bueller?...Bueller?)
