Hi Mate, I’m glad it was helpful! To be honest most of what I tackle isn’t that hard it’s just a little bit daunting sometimes which is why I have built up quite a Mercedes playlist now to help everyone out: th-cam.com/play/PLor5qdyoV_nRcb5hDS-z6z1wUHNednb2h.html Cheers Drew
@@DrewFixIt exactly I almost went to my mechanic but had no openings so I just went for it. The aux Battery being low wouldn't let me shift into reverse or park so it was a big deal for me to get it fixed
I like your idea of using sticky tape, years ago when I was a young apprentice I was told to use a small amount of vaseline on the nut .. hope it helps others.
Your videos are always top notch Drew. Made my life much easier once again. 2 quick notes, for me the air vent and battery cover plate were connected with a pin, therefore slightly more tricky when inserting back. The Aux battery leads seemed to be connected on the far side for the battery housing. For the new one I left them on the near side, noting the +/- leads. Thanks again mate.
Some ML350's have the aux battery behind the main battery, others have the aux battery behind the rear passenger side wall. My neighbor has a 2011 ML350, can someone tell me exactly where that aux battery is before going through the painful process of checking?
Ok first thing. Bending the tab down will not allow you to slide the battery out. You must remove the 2-10 mm nuts on the floor below it, pull the passenger side floor trim, pull carpet back and remove a t-25 torx Then pull towards inside of vehicle so you can remove the 10mm nut that holds the bracket in place to secure the battery. If you do not remove that bracket you will short the battery to ground. Bracket must be removed.
The battery should be in the engine bay, anyway. The battery and control model are very close to the ground in that position. Do you know if there is a drain hole in the bottom, which would allow water to enter? I would estimate water only 30 cm's deep could enter perhaps.
There is a tool that takes a 9 volt battery that plugs into your cigarette lighter/12V outlet that keeps the Memory ALIVE when changing any battery. This is a must because many problems like a no start can occur 😢
Hi Mate, the most common cause of this is actually a weak battery. This may sound silly, however did you check the voltage of the battery before installing it? Perhaps it was old stock? Cheers Drew
Hi Mate, sorry I can't remember the exact aux Panasonic battery I used and I can't seem to find it on Google for some reason. However, something like this is very good value for money and will serve the purpose well at around $20 drypower.com.au/power/product/25804/vrla-agm-backup-main-power--12v-backup-&-main-power-battery.html Cheers Drew

Hi Mate, it is possible that one of ours has been changed out and not back the same previously so absolutely thanks for sharing! Cheers Drew
How did you get the battery to slide out when the terminals are taller than the bracket over the top?
I’ve been struggling for hours to get the fing thing out and it is still in there
Got to push the terminals flat to get it in or out I flipped it
So how do you get the battery spades past the cage? thats the hard part.
The sides looked raised on the cage, are they not?
@@eschrader no. In fact it's hooked in by a tab on one side.
Thank you for this video.

Hi Bill, a 2011 ML350 will be a W164 chassis, so it will be exactly the same as mine with the AUX battery behind the Main Battery. Cheers Drew
@@DrewFixIt Thanks so much!
Great video!
Glad you enjoyed it! Cheers Drew
Excellent tks Tpmerc

Is the Aux battery rechargable?
Yes mate, however your car will be recharging it via the alternator! Cheers Drew

Agreed should be in the engine compartment!! I assume there is a drain hole, so no river crossings folks! Cheers Drew
Thanks Mate!

Hi Mate, not required and infact not recommended for Mercedes sensitive electronics! Cheers Drew
I CHANGED MY AUX BATT. AND NOW MY RADIO SHOWS ANTI THEFT ACTIVATED. HOW DO I FIX THAT ???

@@DrewFixIt Well I had changed the aux battery then this happened
Replaced main battery last year
@@DrewFixIt THANK YOU FOR YOUR HELP I WILL CHECK IT WHEN WIFE GETS HOME 🤙🤙🤙🤙🤙🤙
@@johnmiller4553 no problems! Please let us know how you get on? Cheers Drew
hey, what is the exact generic auxiliary battery that was used ?
