The AdBlue injector doses fluid into the exhaust so the SCR catalyst can reduce nitrogen oxides.
What does it mean?
The AdBlue injector doses fluid into the exhaust so the SCR catalyst can reduce nitrogen oxides.
Symptoms to look for
A dosing fault can cause an AdBlue warning, SCR fault, countdown, poor dosing performance or visible crystallised deposits around the injector.
Possible causes
Crystallisation, blocked dosing, wiring, electrical failure, incorrect pressure or a fault elsewhere in the SCR system may be involved.
What diagnostics check
Diagnosis checks commanded dosing, system pressure, injector operation, wiring and physical deposits while considering the pump and quality of the fluid.
What should happen next?
Cleaning or replacement depends on the actual condition. S7 Remaps can diagnose the injector-related fault rather than applying an unsupported reset. Do not use a software change to hide an unresolved mechanical or emissions-system fault. A proper diagnosis should establish the cause before a solution is chosen.

Frequently Asked Questions
It can. The exact warning depends on the vehicle and fault, so the stored codes and live data need to be interpreted rather than guessed from the dashboard message.
