As the world’s first automobile manufacturer BMW now equips all new diesel models as standard with a Fehlbetankungsschutz from. The innovative system keeps customers before a serious mistake at the pump. The accidental introduction of a gasoline Zapfpistole by a corresponding device on the tank nozzle prevented. The technique had been applied in a variety of BMW models with diesel engines and is now worth more than the first time all series across from the factory and installed at no extra charge.
Per year to only the ADAC road guard in Germany in more than 5 000 cases due to a technical assistance Fehlbetankung. The consequences of misfortune to eliminate a lot of effort, possibly with high costs. Even if the error before the engine start is noticed, leading to the emptying of the tank, cleaning the tank, the pipes and the pump and the change of the filter is no alternative.

The high number of Fehlbetankungen shows that even a brief distraction is enough to get to the gas station at the wrong Zapfpistole to bite. Just look at those in particular need to be drivers, who often rent a car or cars from different companies use fleet – especially as the performance characteristics and the measures for sound insulation in modern diesel engines have led to gasoline that differences barely noticeable. The difference in diameter of the Zapfpistole mainly prevents the erroneous filling of diesel into a petrol-tank vehicle with a narrow nozzle, can be reversed in a hurry, however, without further fueling the tap for petrol in the tank opening of a conventional diesel vehicle to be pushed.

BMW drivers are therefore now in the process effectively supported the tank, to avoid confusion. The BMW diesel models installed Fehlbetankungsschutz is designed so that it at the gas station only to use a diesel Zapfpistole permits. The tank opening these vehicles has a ratchet, which is designed so that only a standard diesel Zapfpistole can be unlocked. With the smaller diameter petrol-Zapfpistole can tank nozzles are not open.

Even the exception for situations in which a diesel vehicle is not at the pump, but using a reserve fuel canisters, it is designed Fehlbetankungsschutzsystem. Narrow cutouts on the outer side of the tank opening to allow fuel injection of smaller quantities. The refueling of the canister thus requires a bit more care – and reminds motorists while out at the right fuel to grasp.
