Hello, now I get annoyed again over my tank control light. Although I have fuelled this morning, the tank warning light lights up on shortly after starting and leaving. At some point after 10 or 20 KM the tank indicator then shows fully and the lamp goes off. Can also happen that the process repeated after a short time display zero gasoline and indicator light is again. Would not like to expand the complete tank you do not get there from above ? mennzer
