Auxiliary battery W213

[JT1]

I’ve had the auxiliary battery malfunction warming for a week or so.
I’ve googled it, found it’s not a battery at all but a voltage regulator - found a good YouTube tutorial and found the part - genuine and not so

Here’s the part https://xenons4u.co.uk/mercedes-benz-a2059053414-voltage-converter.html

Here’s the tutorial

I’m assuming “passenger side” is regardless of left or right hand drive?

My fuse box is passenger side so I’m assuming all the rest is too and it will all be just a mirror of the RH drive video? I know I could just yank the trim out and find out but I’d rather know first.

Hoping it’s as easy as it looks!

Right, well, thank heavens for YouTube, eh!

I once did a leg amputation on you tube so, nothing to lose. Wish me luck…. hopefully more luck than I had with the dining table!
