Introduction
The tank filler neck in diesel vehicles can be fitted with a misfuelling prevention device ⇒ Fig. 196.
The misfuelling prevention device ensures that the vehicle can be refuelled only using diesel pump
nozzles.
Turn the diesel nozzle to and fro if the misfuelling prevention device gets stuck. This can open the
misfuelling prevention device and make it possible to refuel the vehicle. If the misfuelling prevention
device remains closed, proceed to a qualified workshop to have the system checked.
If it is necessary to refuel the vehicle using a spare fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to fill the tank with fuel, pour the diesel into the
tank extremely slowly in very small quantities.
