Lost! One Auxiliary Battery... W213 2017 Hybrid

[bogy]

Hello all,
I've had my 2017 E350e for 18 months or so now, and love it! Especially the acceleration, and ride.

Warning "Auxiliary Battery Malfunction" came up a dew days ago. I took it to dealer - not covered by Extended Warranty and they want over 500 quid to fix!

Thought I'dl ook into it myself, at least to understand what I'm paying for!

But can't even find the thing!

(According to google they can be in a number of places depending on the car and exact date of manufacture).

Very grateful if anyone can shed any light...
1) where excyly is it located, and how do I get to it (on my car 2017 E350e (hybrid), happy to PM vin)
2) what's the part number / cost
3) does it need any coding etc, or once found can I just fit it?

many many many thanks!

Just goes to show the profit the main dealer is making on a battery change!
Shocking

Under front passenger footwell, carpet and under carpeting panelling removed. Not meant to be a "user serviceable battery."

Main battery needs to be disconnected as well when doing this.
