AdBlue (diesel exhaust fluid) is used in selective catalytic reduction (SCR) systems on modern diesel vehicles to reduce NOx emissions. When the AdBlue system develops a fault — whether that’s a faulty sensor, contaminated fluid, a pump failure, or a system that’s been exposed to incorrect fluid — the consequences can be severe: warning lights, reduced performance, and eventually a vehicle that won’t start.
AdBlue system faults can also arise from vehicles being filled with the wrong fluid, or from systems that have developed faults requiring calibration or component attention. Diagnosing AdBlue issues accurately is important, because the wrong approach can create further problems.
We carry out a thorough diagnostic of the SCR and AdBlue system, identify the root cause of the fault, and recommend the most appropriate solution — whether that’s component repair, system calibration, or a software-based resolution. We explain everything clearly before any work begins.

Frequently asked
What causes AdBlue system faults?
Common causes include faulty sensors, pump failure, contaminated or incorrect fluid, and system calibration issues. Some faults are straightforward; others require detailed diagnosis.
My AdBlue warning light is on — can I keep driving?
AdBlue warnings escalate. An early warning may give you time to act; a later-stage warning typically means the vehicle won't restart once stopped. Address it promptly.
Will you need to drain and refill the AdBlue tank?
If contamination is the cause, yes. In other cases, the tank and fluid may be fine and the fault is elsewhere in the system.
How long does AdBlue system diagnosis and repair take?
Diagnosis is typically under an hour. Repair time depends on what's found — we'll give a clear estimate once we know the fault.
