Condition
Customer states that the vehicle cannot be refueled due to difficulty with inserting the fuel pump nozzle into the
filler neck.
Technical Background
Beginning with MY2013, the filler necks of all A3 TDI
vehicles are equipped with a misfueling guard
(Figure 1). The guard minimizes the likelihood that
fuel other than ultra-low sulfur diesel will be put into
the vehicle.
The misfueling guard is designed to remain in a
locked position when a nozzle with a diameter
typically suited for non-diesel fuels (approximately
13/16”, or 20.6mm) is inserted, to prevent further
insertion of the nozzle into the filler neck.
A nozzle with a larger diameter typically suited for
diesel fuel (approximately 15/16”, or 23.8mm) will
unlock the misfueling guard when inserted, allowing
the nozzle to be further inserted into the filler neck.

Service
Explain to the customer the purpose of the misfuel guard, and how the guard is designed to function.
Also state that some refueling stations may have damaged or worn nozzles with diameters that are out-ofspecification, and that such nozzles may not be able to unlock the misfueling guard. Suggest that in such cases,
the customer try turning the nozzle before inserting it into the fuel filler neck, try using a different fuel pump, or see
an authorized Audi dealer or authorized repair facility for assistance.
Do not replace the fuel tank, as this is a normal condition.
