AdBlue® is a biodegradable, water-based additive that’s been developed specifically to make your engine more environmentally friendly. A Volkswagen fitted with AdBlue® technology has reduced nitrogen oxide emissions. When it’s time to top up, a warning message will appear on your dash 2,400km and 1,000km beforehand.
The system uses a Diesel Oxidation Catalyst (DOC), combined with a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) which utilises the periodic injection of the AdBlue® solution. The solution is stored separately from your fuel tank and is pumped in small quantities into the exhaust when the engine is running – breaking down nitrogen oxide into water vapor and nitrogen gas.
AdBlue® is a corrosive liquid, so we advise you wear protective clothing when handling. If it touches your eyes, skin or respiratory organs or is swallowed, rinse with plenty of water for at least 15 minutes and seek medical help immediately. Do not try to induce vomiting unless recommended by a doctor. If small quantities of AdBlue® come into contact with the vehicle’s paintwork wipe them off and if necessary rinse the area with water.
