AdBlue Diagnostics
Mobile across Birmingham & the West Midlands
Seen an “AdBlue system fault” message, a warning light or a countdown? Start with a proper diagnostic. We come to you, scan the ECU and live SCR data, and tell you exactly what’s failed — NOx sensor, pump, injector, dosing module or crystallisation — and what it’ll take to fix. No guesswork, and a clear quote before any repair.
What is an AdBlue diagnostic?
An AdBlue diagnostic is a full scan of the engine ECU and SCR system to find the exact cause of your warning, “AdBlue system fault” message or countdown. We read live NOx, dosing and temperature data and the stored codes — P2BAF, P13DF, P13F6, P20EE and similar — so we can tell you whether it’s a NOx sensor, pump, injector, dosing module or AdBlue crystallisation, and exactly what the fix involves. It’s the right first step before any repair.
Sensors, pumps, dosing & crystallisation
We test NOx sensors, the AdBlue pump and injector, the dosing module, SCR temperatures and AdBlue quality — and check for crystallisation — to find the real cause, not just the symptom.
Live data and stored codes, read on-site.
Fix the right thing, once
AdBlue codes point to a system, not always a single part. A proper diagnostic means you only pay to replace what’s actually failed — not a guess that comes straight back.
How the diagnostic works
A quick, mobile process — we come to you.
- Tell us the symptoms. Share your make, model and the warning, message or countdown you’re seeing so we arrive prepared.
- We come to you. Our specialist arrives at your home, work or yard anywhere across Birmingham & the West Midlands with full diagnostic equipment.
- Full ECU & SCR scan. We read live SCR and NOx data and all stored fault codes to pinpoint the exact cause.
- Clear report & quote. You get a plain-English report of what’s wrong and a quote to put it right — repair or, for off-road vehicles, a software solution.
Common AdBlue faults we find
The faults a diagnostic most often uncovers behind an AdBlue warning.
Failed NOx sensor
The most common cause — upstream or downstream NOx sensors fail and trigger warnings and countdowns.
AdBlue pump fault
A failed or blocked dosing pump stops AdBlue being metered into the exhaust.
Blocked injector / crystallisation
The AdBlue injector crystallises and blocks, leaving white residue and dosing faults.
Dosing module fault
The control module that meters AdBlue fails, so warnings won’t clear even after a new sensor.
SCR & temperature faults
SCR catalyst or exhaust temperature issues that stop the system converting NOx correctly.
AdBlue quality / level
Contaminated or crystallised AdBlue, or a faulty level sensor giving false low warnings.
After the diagnostic
Once we know the fault, here’s how we put it right.
Genuine repair
For road vehicles we replace or repair the failed part — NOx sensor, pump or injector — keeping you road-legal and MOT-ready.
Crystallisation clean
Where the injector or system has crystallised, we clear it and confirm correct dosing.
Software solution
Where component repair isn’t the right route, a permanent ECU solution resolves the fault for good.

AdBlue diagnostics — common questions
Quick answers before you book.
What does ‘AdBlue system fault’ mean?
It means the SCR system that injects AdBlue has detected a problem — commonly a NOx sensor, pump, injector, dosing module or crystallisation. A diagnostic reads the exact codes and live data to confirm which, so it’s fixed right first time.
Do I need a diagnostic before a repair?
Almost always, yes. AdBlue codes point to a system, not always one part. A diagnostic means you only pay to replace what’s actually failed, rather than guessing.
Do you really come to me?
Yes — we’re fully mobile and come to your home, work or yard across Birmingham & the West Midlands, 7 days a week, with all the equipment needed.
