yes, it works a treat, if you look closely at picture you may see red bits in the nozzle, these have to be pushed to open and the green unleaded nozzle wont open them. its perfect, i have it and know it works. I was so lucky not like a friend with an 08 jetta, he filled to top with u/l and drove, cost him over 1500 so far and engine still not right.
AA charge 250 to come out around dublin to drain etc plus parts. this gizmo is 48 euro or thereabouts. a godsend. there is a newer better version with more red catches so it is easier to fit and does more models.
