One of the latest techniques used to clean up diesel emissions is known as selective catalytic reduction (SCR). A solution of urea in water is used to treat exhaust gases and remove harmful pollutants, including nitrogen oxides (NOx), of which nitrogen dioxide (NO2) is the most harmful. What happens if you run out of AdBlue? If you run out of AdBlue while you're driving, then the engine's power and performance will be reduced to limit its emissions. Once you've stopped, you won't be able to restart the engine if the AdBlue tank's empty. How long does a tank of AdBlue last? 18 months Provided that it is kept in the optimal conditions — out of direct sunlight and at a temperature between -6°C and 25°C — your AdBlue can last up to 18 months in storage. If you store it at a higher temperature than this or in a vented container, the shelf-life will only be around 6 months. How many miles after AdBlue light comes on? Most cars will manage around 12,500 miles between AdBlue top-ups according to Citroen, which fits its cars with bigger tanks than other manufacturers. When the warning light comes on, the car will countdown the number of miles left until the tank is expected to run dry, at which point the car will no longer start. Do all new diesel cars use AdBlue? Many diesel cars registered after September 2015 use AdBlue to reduce emissions. In general, if you own a Euro 6-compliant diesel Audi, BMW, Citroën, Jaguar, Land Rover, Mercedes-Benz or Peugeot, it's likely to use AdBlue technology. There's often a clue in the car's model name, which may have 'Blue' or 'SCR' in it.
