AdBlue faults — sorted before the countdown ends

Common AdBlue problems we see

The SCR system has several failure points, and the warning message rarely tells you which one it is:

• Faulty NOx sensors — the most common culprit
• AdBlue pump and injector faults
• Crystallised AdBlue in the tank or lines
• Wiring and control module faults

How we approach it

We scan the system, check live data from the NOx sensors and dosing system, and pinpoint the actual fault. You get a straight answer on what needs fixing and what it involves — before you spend money on parts you might not need.
