Thank you Ralph, I was afraid it could be the problem, but is it possible so lock the very thick filler pipe without breathing the tank. The 3-4 liters oil could be go in for hours not belching but (slow) leaking. I think you are right! The filler pipe (about 2 inch thick) joins to the tank approximately 3-4 inch high from the bottom of the tank. When we realized the lock, the oil level in the tank must be above the feed pipe, so the filler pipe was full of fuel at same level.
While the water is denser, in the resting car the water should be at the bottom of the tank. (possible frozen?) The fuel pump suchs the fuel from the lower part of the tank of course and the car did not recognized any water in the fuel system. (The car has water_ recognize sensor, but fortunately we never seen such a signal for today). So I could not imagine that the tank had 3-4 inch ice at the bottom in an absolutely horizontal staying car. Unfortunatelly I never seen where is the upper end of the breathing pipe, I will look for. . .
