Replacing rear light unit

[Altamar]

Apologies if this has been asked before but I couldn't find a suitable thread.

I have damaged a rear light unit on my 2014 facelifted E class W212. If I manage to find a used one in a scrap yard (or splash out for a new one) are they just plug and play or do they need to be programmed in in any way?

Thanks.

As far as I am aware it’s just straight swap , plug in.
