2014 GL550 Part Number for Battery Cover etc

I recently purchased a 2014 GL550, I ordered it online and the seller agreed to pay for any issues found upon delivery. Well its missing the battery cover and heater duct from what I have been able to identify. I believe this is the duct part number 166-831-18-46 but I cannot find the cover that would actually cover the battery and duct up. It has grey leather interior but I think its likely the cover is just black to match the carpet? The one other oddity I found is in the passenger foot well on the far right side there is a small gap between the carpet and the side wall. There are a number of wrapped wires under that part of the carpet and at least one terminal plug, I would have thought there'd be some sort of plastic cover on the floor under the carpet to protect these but I can't find anything in the parts diagrams I have located online.
I have been searching here: https://www.benzpartshq.com/auto-par...-v8-gas-engine but it doesn't make it terribly easy to find a part if you're not sure if it even exists or know what it would be called.

Can you gu

Battery missing cover and heater duct...anything else?


Gap in passenger foot-well.


Wires next to / under passenger foot-well gap. Is there a cover that is supposed to be here or something?

Any help is appreciated and if this things look indicative of some major issue please let me know so can send it back, I have about a week to decide if I will keep it.

Battery cover is 1666800218

As for the front there is not an extra cover missing. Likely the carpet has shifted for some reason or was cut. This could explain the missing battery cover.

Side note the battery area is missing another piece that covers it. I can get the part number but will have to be later. The piece is a pain to remove I am told and will just wait for my friend who builds these to come play with it.


Hope these pics pics help you

Sorry you returned that one - did you find another of the same model?

For future reference I've found this website to be extremely helpful in identifying MB parts: https://www.mbpartsstore.com/ Just designate your year, choose MB or Smart, and pick your model + trim level and you're good to go!
(good to go if you've acquired another Mercedes that is)

Best of luck in any case!
