Mine is a 20l plastic diesel can bought here in Germany. Used numerous times on my previous cars, 5 of which were Skoda diesels. It just doesn't fit this new type filler neck without the use of the little adapter. Bought from Ford at a cost of 7 euro [emoji2]

 

Glad you've got it sorted.

I have to go to the Skoda Accesories place today to collect some parts so I will ask if there is an official VAG tool also.
