Moin dear forum community, in the diesel filter of my 240 D 3.0 was water. So there is probably also water in the tank. Actually incomprehensible because this year I have already consumed 4 to 5 tank fillings. The car runs now again but the water has to be bound. Which of the many available on the market is recommended? Would it make sense to thank the Benz over the winter e.g. with Ultimate Diesel?
