Can I use the parts from any year of W212 for my 2014 e350?
 

Hello,
I have 2014 Mercedes-Benz e350 (base). I need to change passenger side door and fender, can I use parts from 2012 or 2013? Will they fit?
Thank you!

yes

I am not convinced one can use a pre-facelift (2011-12) fender on a 2014 facelift model

OP does not say whether it's a front or rear fender. Assuming front fender, I have doubts. But someone more familiar than me will have a better answer..

I agree

I am seeing them as compatible, the part number is A2128801218 (right side sedan fender) The E63 is different; which is A2128800818 (right side E63s & E63 fender)

I am pointing out the only two possible right side fenders ever made for the w212 sedan... because DFWdude and you believe that the pre-facelift and facelift are different. You act as if i am providing non-relevant information here or personally insulting you here.

If i remember correctly, fenders should be the same from 2010-2016 on the E350 and the doors are also showing the same part number across the same years as well.

Thank you guys. I think fenders are compatible. Now I am worried about doors. My 2014 E 350 sedan needs passenger front door, will the door from 2013 e 350 sedan fit? Any thoughts?

Im sure they were the same 10-14 after that .... no idea

The only thing that should not be cross compatible between pre and post face lift would be headlight/taillights, front/rear bumpers along with any grille or molding pieces attached to it, and hood.
