A few months ago, I posted here about rust appearing on the panel around the fuel filler area on my car. Upon closer inspection, this rust had started on the rear side of the panel and penetrated through to the outside. The car is a 2014 Citigo SE with only 20k miles showing. After a lot of back and forth conversations with Skoda, they finally inspected the car in July 2018 and agreed it was a manufacturing defect. The car was taken to an approved body shop where it remained for over a month. I understand that the rear quarter panel was replaced and also noticed when the car was returned, plastic rear wheel arch liners have been installed which will prevent future issues. The car never came with these from the factory and the fuel fill tube and poorly finished panel edge where the fuel fill housing sits, are mud, salt, water, dirt and everything else, traps. They also installed a liner on the passenger side. It would be interesting to see if these liners are now installed on new cars from the factory. I looked at a 2015 car on the Dealers forecourt and it too was showing the signs of rust starting around the fuel filler, so it is obviously a common problem. Thanks to Pulman Skoda of Durham for taking care of this issue for me.
