Auxiliary Battery Replacement

[Jordan12291257]

Hi All,

I have been getting a warning message on my dash saying “Auxiliary Battery Malfunction”. I have read about this and most people advise to replace. So I have ordered a new battery of the internet however I am struggling to locate where the aux battery is - I drive a CLA 220d 67 Plate (Estate). I’ve seen a few videos saying it is under the passenger footwell, I have looked here above the fuse box there is a small black box but this doesn’t look like the other aux batteries on the videos. If this is it I am unsure on how to take it out / unlock it to replace it. Am I looking in the right place?

Any help would me much appreciated.

Thanks

Scan the 3d rescue barcode on the door pillar with your mobile phone camera , it'll take you to a website showing you locations of all batteries.

Looking on you tube points to passenger footwell under a black plastic cover ,near the pollen filter housing.
