Hello guys, about 2 weeks ago everything started… Vehicle always stank for gasoline… nothing could be found at Audi… Today I noticed that from the wheelhouse (right in front) petrol dripped… right to the friend and everything opened… Behind the cover is a black box and there drips gasoline out. The line from the tank leads in there and a line leads back to the engine… What is this box? Would have now typed on the filter but I am not sure… and how can I fix the problem? Have now for the first time clamped the black box and connected the two lines with a clamp.. direct injection is destined harmful to the engine or? is an Audi Cabrio 2.6 Bj 96
