The presence or absence of an auxiliary battery in my 2016 S212 220 Bluetec 4Matic is uncertain to me. There is a broken QR code on the B-pillar that cannot be read.
The weather isn't nice enough for me to disassemble half the car in search of a replacement part, and the online parts catalogue is somewhat vague on the topic.

You can find the aux in the boot or on the side of the dashboard if your vehicle has a start/stop or steering column shifter; the sequence is the identical, though. How do you enter the VIN into the EPC?

I can control the up and down motion.
Unfortunately, the online EPC site I previously used is currently inaccessible due to Russian advertisements that obscure the images and, well, pretty much everything else as well. It's worth another go, so I will...

Just look on the fuel flap for another QR code sticker. One is available on the 2015 E350 and 2017 GLA models.

You won't find an extra battery pack in my vehicle—not even in the front or back.
