If your dashboard is showing a UREA or AdBlue warning light, derate, or “engine power reduced” message, it’s almost always the SCR (Selective Catalytic Reduction) system flagging a fault a blocked injector, failed NOx sensor, crystallised dosing line, or a failing pump. Left alone, most systems force the engine into limp mode or refuse to start at all.
We carry out UREA removal, UREA delete and full UREA system repair for trucks, vans, cranes, excavators and static plant across London and the M25 area. Our mobile technicians come to your depot, yard or roadside so your vehicle stays off the ramp and back to work the same day, whether you need a permanent delete or a proper repair to keep the system running as intended.

Frequently Asked Questions About UREA Services
What's the difference between UREA delete, removal, repair and bypass?
What causes a UREA system fault?
Can I drive with a UREA warning light on?
You can usually keep driving initially, but most systems will start a countdown (often measured in miles or engine starts) after which the vehicle is forced into limp mode or won’t restart. It’s best treated as urgent rather than ignored.
What happens if the countdown reaches zero?
The engine will typically restrict to a very low speed (limp mode) or refuse to restart entirely until the fault is cleared, which usually means arranging a diagnostic and fix before the vehicle can be used normally again.
Why does my UREA fault keep coming back?
Usually because the underlying part the injector, pump or sensor hasn’t actually been replaced, just the fault code cleared. That buys a short window before the same fault resets. A proper repair replaces the failing component rather than just resetting the ECU.
How much does UREA repair cost?
It depends on which part has failed and your vehicle type we confirm a fixed price in writing after an on-site diagnostic, before any work starts.
Is a UREA delete legal?
(Match legal wording used on live AdBlue Delete FAQ confirm exact phrase with legal/compliance before publishing.)
How long does it take?
2–3 hours on-site, most jobs.
