Hello guys, the following problem !!! With my Omega B 2,5 TD Bj:1998 I have been observing two tank fillings as soon as I go under the 20 he mark on the tank watch and I want to start my car that he starts badly. And sometimes I also have a performance hole at about 90 km/h But if he has more in the tank the problem is not there !!! Thought already on the glow candles, but I made them new. So now I am finished with my Latin. Does someone know the problem and knows RAT ???
