Using AdBlue

depending on the manufacturer and model so it's best to refer to the owner's manual before you start. 

Aspartoftheoveralldrivetoreduceemissions, and to complywiththenewEuro standards, more and more diesel cars now include SCR (Selective Catalytic Reduction) technology. Used in the right way, SCR can help to reduce Nitrogen Oxide (NOx) emissions by as much as 90%, with fuelefficiencyalsoincreasingby between 3% and 5%. 

How will I know when it's needed? It's important to take action as soon as you see any relevant warning lights on your dashboard. There are three possible warnings: FirstWarning-advises you thatthe AdBlue®tank is getting low. 

For the technology to work, vehicles need to be fitted with a special tank for storing a liquid-reductant agent known as AdBlue®. Soifyourvehicleisfitted with AdBlue® there are a few things you'll need to know. 

Second Warning-will gives you a mileage range and sometimes is accompanied by an acoustic warning. 

What exactly is AdBlue®? AdBlue® is a mixture of water and urea, which you top up periodically, as you do with fuel. As you drive, AdBlue® flows from the tank into the exhaust pipe via a dedicated catalyst. The effect is a chemical reaction that converts most of the NOx molecules into nitrogen and water. This is then released into the atmosphere as steam. 

Final Warning-at this point the vehicle will either go into limp home mode (run at reduced power) or will not restart once the ignition has been switched off. 

Who pays for the AdBlue®? Because it's a solution you top up periodically, as you do with fuel, the costs are not covered by the maintenance contract and are therefore payable by the driver of the vehicle. The only exception to this is if the service
