Thank you very much bro my 2016 C300 with 62k miles just started giving me the same messages unlike you I use my car heavily but either way this is something I can do myself instead of going to the dealership to be charged ridiculous amount of money God bless you bro thanks again!! ..Respect!!

I just followed this minute by minute and it worked perfectly. Took me just under one hour. Cheers my guy, you saved me £150!

Just wanted to watch someone else do it before I tackle it. My 2016 with 42k miles just started getting the same message.

Hello friend, do you know where the auxiliary battery of the Mercedes Benz c300 2008 4 magic is? If you help me, I would appreciate it.

very helpful. thanks

On the mercedes website it says you can do it through the hood. Which way is better?

What is the name of this part and where can I buy it. The link for the eBay is expired. Thank you :)

When you had this battery message on instrument cluster, was the Eco stop/Start workings. I have GLC 2018 that has stop start stopped working and I have a feeling it might be that battery causing the problem.

Thanks!

It would be helpful to list the socket sizes you use as you use them, but good video otherwise

Thank you

hows the aftermarket convertor holding up do you have link from where you got it?

I had the aux battery switched and I still receiving aux battery malfunction on display. Lost all sound from radio, (it comes on but no sound) no backup cam, navigation, and window won’t roll up with one tap. It rolls up and comes back down. Been to the dealership 2x! Any suggestions?????????????

Would you please share part number, and where did you order it from. Thank you.

What's that black box next to the auxiliary battery?

Did you feel a power loss by any chance during and after the part was replaced?

How is it now,?

6:24 the auxillary battery

How did the aftermarket battery is doing so far? so far so good?

My message is still there after they changed it. Not sure how to reset myself

Why does Mercedes insist on putting it in a place so hard to access if it’s a part that needs to be replaced?

I have an actual battery in there??

How much it cost for the battery?

BMW & Mercedes Benz finished no more , it becomes grabbed a cheep collections from Swedish Dacia and the rest fabrications from Taiwan n Chaina with cheep silly design , no more expert designer in MB or BMW as all them been terminated.. The last quality MB was W210 & w211
