Weird how sometimes, my home charger is an easy fit, other times it's a lot of wiggle and jiggle....even though I feel like i'm doing the same thing every time. ¯\_(ツ)_/¯
Never had an issue where I couldn't get it in, though; however, I recently had issue where I couldn't open the charging port "door" - the "OOOO" Audi rings section wouldn't release. Even pulled on the little tab. Nada.
Eventually had to take to dealer to get it replaced (with two weeks remaining on 4yr. warranty) - phew!
