When we were stripping and cleaning the inside of the camper we noticed that the side door was not running as smoothly as it should be. Upon closer inspection we noticed that the lower guide assembly (252843405A) was showing signs of wear.
We managed to secure a new one on an overnight carriage and it was an easy fix.
As you can see the wheels that help guide the door into position have a lot of play which they shouldn’t be able to do. This was enough to prevent the door from sliding smoothly.
A new 252843405A Volkswagen Camper T25 Lower Guide Assembly replaces the entire running guide and the door is now running how it should be.
