AdBlue warning on your dash, or a countdown saying the engine won't restart? We diagnose and repair complete AdBlue (SCR) systems in our Northampton workshop: pumps, heaters, tanks, injectors and NOx sensors, for cars and vans of all makes.
AdBlue (diesel exhaust fluid) is injected into the exhaust by the SCR system to cut NOx emissions on Euro 6 diesels. When any part of it fails, the car warns you, limits power, and can eventually refuse to restart.
We find the actual cause with dealer-level diagnostics rather than guessing, then repair or replace what's needed: AdBlue pumps, tank heaters, level sensors, injectors (dosing valves), NOx sensors and wiring, followed by the correct coding and adaptations.
Book nowFull SCR system scan, live data and fault code analysis to find the real cause.
We check AdBlue quality, pump pressure, heater circuits, sensors and wiring.
Faulty parts are repaired or replaced with quality components.
Adaptations and resets are carried out, then a road test confirms the warning has gone.
Our workshop is at Moulton Park in Northampton, a short drive for customers from:
For a short while, but most cars count down to a point where the engine will not restart. Book in as soon as the warning appears to avoid being stranded.
Sometimes, but if the warning stays on after filling up with fresh AdBlue there is usually a fault with the pump, heater, sensor or injector. We diagnose it properly before replacing anything.
No. Removing or disabling AdBlue/SCR on a road vehicle is illegal in the UK and will fail the MOT. We repair the system so it works as the manufacturer intended.
Cars, vans and 4x4s of all makes, including Peugeot, Citroën, Vauxhall, Ford, VW Group, BMW, Mercedes and Land Rover.
