Audi A6 Typ 4G: Completing AdBlue refill

Applies to: vehicles with selective catalytic reduction

Closing the filler neck

  • Turn the cap on the filler neck to the right with the wheel wrench until the cap clicks into place.

    This tightens the cap to the specification.

  • Then press on the left side of the tank door until it latches.

After filling

The vehicle must be driven so that the system recognizes that the AdBlue was refilled. This can take several minutes.

  • If there was no AdBlue left in the tank and a range of 0 mi (0 km) was shown in the display, switch the ignition on for about 30 seconds before starting the engine.

Tips

AdBlue can freeze at very low temperatures.

If this happens, the system will not detect that the AdBlue was refilled and it will continue to inform you of the low AdBlue level. The message turns off as soon as the tank thaws out again.
