What is an Audi DEF Injector?

An Audi DEF (Diesel Exhaust Fluid) Injector, also known as an AdBlue injector, is a vital component of the Selective Catalytic Reduction (SCR) system in modern Audi diesel vehicles. Its purpose is to precisely inject DEF into the exhaust stream, triggering a chemical reaction that converts harmful nitrogen oxides (NOx) into harmless nitrogen and water.

This process is crucial for meeting stringent emissions standards and reducing the environmental footprint of diesel engines. A functioning DEF injector ensures optimal performance of the SCR system, improves fuel efficiency, and prevents engine warnings or limp mode related to emissions faults.
