AdBlue® (Diesel Exhaust Fluid)
To help ensure proper diesel engine operation, you need to refill the AdBlue® tank when the warning light in the Driver Information Center on the instrument panel comes on.
The driver will receive plenty of warning; however, if the Empty Tank! warning appears, your vehicle will continue to run until you turn it off, but will not restart until AdBlue® or a comparable diesel exhaust fluid (DEF) is added. Audi Genuine Parts AdBlue is ISO 22241-1 certified to help ensure consistent quality.
If your AdBlue® tank runs dry,
your vehicle will not restart.
Refill your AdBlue® tank whenever you see the warning light on the instrument panel come on. The AdBlue® warning light will come on multiple times before the tank is empty. How often the tank needs to be refilled depends on your driving style.
