Fairly straightforward, thanks for the tips. Hardest part was putting the plastic tray-panel back in on the right. New battery fixed the problem. Oh, it was hard to find the righthand bolts on that tray, because there's a removable liner that hides them. Baffled me for the first 10 minutes.
Very easy battery replacement. Takes about 10 minutes and as stated, a ratchet with a 10mm socket will do the trick. You'll want to call ahead to your local automotive parts shop to see if they have it in stock. In my case, both O'Reilly's and AutoZone only had 1 auxiliary battery in stock, both at the same price. That said, you can actually do the swap in the parking lot in minutes and have the shop take your old battery when done.
Even easier fix, fiddle with the connectors and then try the car again. Sometimes the battery malfunction disappears. I did this two years ago and it’s been fine since.
Exactly ! how is finding , ordering , and spending at least $150 to buy a new battery , & ultimately replacing it with a new one , an easy fix ❕❔this video just pmo sooo bad ,,,,,, like we all know replacing it will fix the problem duh 😒
do you really need to replace the batt for old mercs , i have a b class w246 , its function is only for start and stop . .which i never use , i havent replaced mine for almost a year and so , still running fine
I’m getting the same message “auxiliary battery malfunction” on my 2013 CLA45 it won’t let me switch from eco mode to sports or manual mode and my parking sensors aren’t working, going to replace the battery tomorrow hopefully that solves the issue

Did you need to remove the main battery or disconnect it first, before swapping out the aux battery?
@@j.gamble2236 Nope - It’s super easy, I actually swapped mine out in the O’Reilly’s parking lot.
Even easier fix, fiddle with the connectors and then try the car again. Sometimes the battery malfunction disappears. I did this two years ago and it’s been fine since.

He didn’t even try to charge it or anything !
Disconnect the negative terminal first!
do you really need to replace the batt for old mercs , i have a b class w246 , its function is only for start and stop . .which i never use , i havent replaced mine for almost a year and so , still running fine
My E class 250d 2014 did this but i just need to change this batery and it will be fixed ?
I’m getting the same message “auxiliary battery malfunction” on my 2013 CLA45 it won’t let me switch from eco mode to sports or manual mode and my parking sensors aren’t working, going to replace the battery tomorrow hopefully that solves the issue
Did it work?
Did it work and solve your issues?
Unfortunately no it had nothing to do with the battery
Can this issue make my display screen not turn on? But my radio work just fine?
Will a bad auxillary prevent my car from starting its a 2014 e350
Either the auxiliary or the Esl steering lock which requires an emulator smh 🤦🏿♂️ i dont lnow why NhtSB dont recall it
I changed my auxiliary battery not even a year ago and I’m again getting the malfunction message
It may be the connectors?
Mine "failed" after a month(brand new battery). I read somewhere that this little voltage converter thingy can cause that error as well.
Changed the battery in the trunk for my 2016 E350, still getting the malfunction message
What are you going to do now?
Possible capacitor issue. I think it's located next to the small battery.
@@stephenrees3502 dealer sold me bad battery
@@MrSamuel8099 did it go off after you got the new battery or was it the capacitor?
@@rubenperez1481 it went away when I got a good battery
How 2007 Mescedes SL550 ?
Is this guy dead?
