AdBlue repairs and deletes for Wales.
Warning light on? Countdown to no-start? We help with AdBlue repairs and AdBlue deletes for cars, vans, trucks, plant and commercial vehicles across Wales.
Trucks and commercials
Support for larger diesel vehicles with SCR, NOx, dosing, countdown and limp-mode problems.
Plant and machinery
AdBlue fault help for plant, machinery, off-road vehicles, agricultural equipment and site-use vehicles.
Real workshop help
We find the cause before changing parts.
AdBlue systems can fail in frustrating ways. A single warning can be caused by crystallised AdBlue, a failed injector, a blocked line, a faulty tank heater, bad wiring, a NOx sensor issue, a software update problem or a genuine SCR fault.
We work through the vehicle properly, explain what we find, and give you practical repair options for cars, vans and light commercial vehicles across Cardiff, Swansea, Bridgend, Rhondda, Newport and the wider South Wales area.

Repairs first
AdBlue Repairs and AdBlue Deletes.
For vehicles used on public roads, the correct route is to diagnose and repair the AdBlue and emissions system so the vehicle remains compliant and MOT ready.
AdBlue delete work is only discussed for off-road, motorsport, export and non-road applications. If your vehicle is road-used, ask us about repair options instead.
Common faults
When to get in touch
"Engine will not start in 500 miles"
Countdown warnings need quick attention. Waiting until zero can turn a repair into a recovery job.
AdBlue topped up but still warning
The fault may be a level sensor, tank module, dosing pressure, injector, software adaption or wiring issue.
NOx or SCR efficiency fault codes
We check sensor readings, exhaust conditions and dosing behaviour before recommending parts.
Crystallised AdBlue or blocked dosing
Contamination and crystallisation can cause repeated faults if the system is not cleaned and tested properly.
Tell us what the dash says.
Send the registration, the exact warning message, any fault codes you have, and whether the vehicle still starts. We will point you in the right direction.
