Understanding the AdBlue System in Your Audi
AdBlue, also known as Diesel Exhaust Fluid (DEF), is a crucial component in modern diesel Audis. It helps reduce harmful nitrogen oxide emissions, contributing to a cleaner environment. The AdBlue system works by injecting the fluid into the exhaust stream, where it reacts with the nitrogen oxides, converting them into harmless nitrogen and water vapor. When the AdBlue level is low, a warning light illuminates on your dashboard. This indicates the need for a refill. Ignoring this warning can eventually lead to the vehicle not starting, as designed to comply with emissions regulations.
