How Audi vehicles work with AdBlue® and TDI Clean Diesel technology.
Audi was a pioneer in the use of an Audi AdBlue® tank system in Diesel vehicles and, as early as 2011, already met the Euro VI standard implemented in 2015! The manufacturer developed TDI Clean Diesel technology to meet the Euro VI standard, which states that, for diesel engines, no more than 80 mg/km of nitrogen oxides can be produced from the exhaust pipe. Only a few models do not use this additive: the Audi A1, the Audi A3 and the Audi TT.
How does TDI Clean Diesel technology work with AdBlue®?
To reduce nitrogen emissions, Clean Diesel technology injects AdBlue® at the engine outlet with a pressure of 2000 bar, just before the gas arrives in the particulate filter. This causes a chemical reaction in the engine exhaust gas and greatly reduces the pollutants. This means that, thanks to this “magic” technology, almost 90% of nitrogen oxide molecules are transformed.
TDI Clean Diesel technology is expensive for the final customer, and its price is even more of a factor than a low vehicle price.
Where can I find AdBlue® for my Audi?
All products marketed under the name AdBlue® are equal and meet the same ISO quality standards. You can find AdBlue® in most petrol stations in 5-l or 10-l canisters so that you can top up your tank yourself.
