What does it mean?
An AdBlue system fault is a broad dashboard description for a detected SCR problem. It is not a component diagnosis by itself.
Symptoms to look for
The message may appear with an emissions warning, countdown, no-start warning or engine light.
Possible causes
Sensors, dosing, pressure, fluid quality, tank, pump, heater, injector, wiring and software communication can all be relevant.
What diagnostics check
A full scan, live-data review and physical inspection are needed to separate a genuine component failure from a secondary or communication fault.
What should happen next?
S7 Remaps can provide diagnostic-led AdBlue support and explain the next repair or servicing step without disabling the emissions system. 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
