Specialized service · AdBlue / SCR
The AdBlue (SCR) system reduces NOx emissions in Euro 6 diesels. When it fails, the vehicle enters a kilometre countdown and may become immobilized. Professional intervention resolves the problem and restores normal operation.
What is AdBlue
AdBlue (DEF - Diesel Exhaust Fluid) is a solution of 32.5% pure urea and 67.5% demineralized water. It is not a fuel additive — it has its own injection system directed into the SCR catalyst after the exhaust, where it chemically reacts with Nitrogen Oxides (NOx) to convert them into pure Nitrogen and water vapour.
If the AdBlue tank runs empty or the system fails, by environmental law, the engine will not restart after being turned off. Crystallization of the liquid can damage the injector, pump and entire AdBlue circuit.
Failure symptoms
Consequences
The AdBlue system is regulated by law. Ignoring warnings is not an option — the vehicle will immobilize. And system failures become progressively more expensive over time.
