A special refill bottle is needed in order to fill the tank with AdBlue.
The flap that covers the tank cap is unlocked and locked automatically by the central locking. The AdBlue filler neck is located immediately to the right of the diesel filler neck.
Opening the filler neck and refilling AdBlue
Press the left side of the flap to open it Fig. 3 -arrow-.
Unscrew the cap on the filler neck anti-clockwise using the box spanner from the vehicle's tool kit Fig. 1.
Take the cap off the refill bottle.
Screw the refill bottle onto the filler neck clockwise as far as it will go Fig. 2 -1-.
To empty the refill bottle, lightly press the bottom of the bottle -2-. Keep pressing the bottom of the bottle until the bottle is empty, or until no more fluid runs into the tank.
Unscrew the bottle anti-clockwise without applying pressure.
Closing the filler neck
Screw the cap onto the filler neck by turning the box spanner clockwise until you hear the cap click tight.
Press the left side of the flap to close it (you should hear it click into place).
WARNING!
- AdBlue can cause irritation to the skin, eyes, and respiratory organs. Wash thoroughly with clean water should you come into contact with this fluid. Seek medical assistance if needed.
- Keep AdBlue away from clothing. Wash thoroughly with clean water should you come into contact with this fluid.
Caution!
- Use only AdBlue that complies with the ISO 22241-1 standard. Do not mix AdBlue with additives and do not dilute it with water.
- AdBlue is not a diesel fuel additive and must not be added to the diesel tank. Mixing AdBlue with diesel fuel can damage the engine and the AdBlue tank system. Such damage is not covered by the warranty.
- AdBlue attacks surfaces such as paintwork, plastic veneer and carpets. Remove spilt fluid as soon as possible with a damp cloth and plenty of water. If the AdBlue has already solidified, use warm water and a sponge. Unremoved residues of AdBlue solidify after a while and can damage the affected surface.
- Do not carry refill bottles in the vehicle all the time, as leaking AdBlue can damage the vehicle interior.
Note
- The tank flap is not locked when you lock the vehicle from the inside.
- The refill bottle holds about 1.9 litres. Always refill with two bottles of AdBlue (3.8 litres) when the refill message appears in the instrument cluster display Link. The ignition must be switched off while you are refilling.
- The vehicle must be driven after refilling. It can take up to two minutes for the system to detect that the AdBlue has been refilled. If the AdBlue tank has run dry and a range of 0 km is shown in the instrument cluster display, the ignition must be switched on for approx. 15 seconds before starting the engine.
- Refill bottles are available from any Audi dealer or specialist retailer.
- Please follow the AdBlue manufacturer's instructions for storage and use.
