Auxiliary Battery Replacement 2016 GLC 300 | Auxiliary Battery Malfunction 2016 GLC 300 

😊🙏

Yep! Thank you so much, my friend 🙏

That's what the OEM part from Mercedes named Auxiliary battery. I believe you didn't do your research.

The falt code or the error message that showed on the instrument cluster said Auxiliary Battery. At the end of the day, it's a module like you described....voltage conveter aka....voltage regulator.

You're welcome 🙏

Thank you very much 😊

Did you have the message that said Auxiliary battery malfunction as well?

It's the basic model.

Yes, my wife's GLC300 is 2016

Yes, it showed the message on the gauge cluster.... Auxiliary Battery Malfunction.

U ever see the code stop engine leave vehicle running - with a battery symbol?

@@michaelbhim7585 No I haven't seen that symbol. It sounds like it needs a new battery or weak battery.

Yes, you are correct.

Did you unplug car battery? Can u send link for glc 2017 300 coupe aux battery@@MrBeeHS

No I didn't disconnect the car battery because it's not necessary.

You can definitely test it, but you have to remove the unit itself and use the equipment which I don't know what equipment the engineer uses to test the device. The only trick that I know is if you get the Auxiliary battery malfunction on your dashboard, it means that the unit is bad. I hope this helps.

It is usually located in passenger front underneath the glove box compartment

Yes definitely will work on 2017 GLC

@@MrBeeHS thank you so much!

You're welcome 😊

It does work. What you can do is to get the part number from the Mercedes dealership and find the same part number on Amazon. The warning will continue to come on and off for a while until the part is totally fried then it stays on.

It's called voltage converter (Auxiliary battery) part number is 2059053414

Thank you again@@MrBeeHS

@@garyfeatherston4850 you're very welcome 🤗

Thanks bro. There seems to be cheaper ones. Are they same thing

You can get it from Amazon (cheapest). It's called voltage converter or auxiliary batter (that's what Mercedes called it).

I am 100% sure there will be no problem buying it from Amazon. The one that I installed was from Amazon still working great. This is the link to the one that I bought from Amazon. maXpeedingrods 2059053414 2054400073 Voltage Converter Module for Mercedes-Benz C-class CLS350 W205 W253 S450 2013-2018 a.co/d/1QEzTRk
