Could AdBlue® be Volkswagen’s go-to solution when it comes to respecting the environment?
Why do some Volkswagen diesels not use AdBlue®?
In order to meet the Euro VI European standard, Volkswagen equips its diesel models with an AdBlue®-powered SCR system, as seen on the Passat and the Touareg. Other manufacturers, such as Mercedes-Benz, also use AdBlue® (a mixture of urea and water) on some of their diesel models. For the compact models Golf, Jetta and Beetle, Volkswagen believes that the 2.0-litre TDI diesel engine is able to meet the emission standards by simply using a catalytic converter that reduces nitrogen oxides (NOx).
For the Passat and Touareg TDI models, AdBlue® is sprayed into the exhaust gas stream to control nitrogen oxide emissions. The AdBlue® tank must be filled periodically, approximately once every 9600 miles (16,000 km). This frequency may be higher if you consume more AdBlue® as a result of your driving style, the ambient temperature or your annual mileage.
How much will a full tank of AdBlue® cost for my Volkswagen?
A full tank will cost around £25–30 (€30–40), depending on the option chosen (from the dealership, at a service station, at the pump or in cans). In the United States, AdBlue® refills are included in the three-year maintenance plan. Volkswagen policies vary from one European country to another: some include AdBlue® maintenance in the annual service while others do not. You can fill up your tank yourself by buying a canister from a filling station and following the tutorial on infodiesel.fr.
