Audi owners will no longer have to worry about accidentally filling their diesel vehicles with gasoline. The company is introducing a mechanism that will have you pumping without a problem.

Right now, you can’t put diesel into a gasoline-powered vehicle because the diesel nozzles are large and won’t fit in the filler neck. On the flip side, gas nozzles are smaller and will fit in the diesel neck. Audi’s new system will feature a flap in the neck that prevents fuel flow. This flap will open if the nozzle hits contact points just below the cap. Since the smaller gasoline nozzle can’t hit all of the contacts at once, the flap ensures that improper fuel won’t be getting into the tank.

Audi’s new flap system is similar to the one used by BMW, who installed this mechanism in all of its diesel vehicles since early 2009. Available for the 2011 model year, Audi’s A4, A5 and Q5 TDI will feature the new system in Europe.

In recent years, more people have been encountering the issue of misfuelling, resulting inconvenient and potentially expensive consequences. This could be the result of the increased refinement of diesel models, which has seen them run nearly as smoothly and quietly as their petrol counterparts.
