P0452 Error Code

[dogsridewith]

Don't put in those last 5 litres.
(When were you finally stopping? When gasoline became visible in the filler neck?)

(Before the last 5 litres, the always "slow tank" could have something to do with something wrong with the vent pipe--skinny pipe next to the fill pipe. I think more likely something w/ the station pump's shutoff system.)
