The tap closes, as if the tank was already full. when I pull out the trunk, then the diesel sprays against me with quite high pressure (the smell hardly gets rid of it again). you have the feeling, in the tank there is a big overpressure. with a little fingertips you can then fill in a liter again until the whole again blocked. for me this has happened already 2 times in a row at two different filling points. e n defect of the pumps can therefore be excluded. what can this be? can you somehow vent the tank myself? because I have to leave tomorrow and the workshop has logically only opened again on Tuesday.
