Diesel Exhaust Fluid (DEF) is another name for AdBlue. If the DEF/SCR system on an off-road, motorsport or export vehicle keeps faulting, we bypass it at the ECU so the warnings, countdown and limp mode stop. Mobile across Stoke-on-Trent, Staffordshire and Cheshire.
Supplied for off-road, motorsport and export vehicles. If yours is used on the road, we will fix the fault properly instead, and it is often less than people expect. See AdBlue repair.
Diesel Exhaust Fluid is the general name; AdBlue is the brand name used on most UK vehicles. It is the same urea solution and the same SCR system.
A DEF bypass reprograms the engine ECU so it no longer relies on that system, done in the software rather than with an emulator box. Your original ECU file is stored first. If your vehicle is used on the road, we will fix it properly with an AdBlue repair instead.
A clean, one-visit job at your home or workplace.
We plug in at your home or work and read exactly what is triggering the AdBlue warning, countdown or limp mode.
You get the cause, the options and the price before any work starts. No surprises, no pressure.
We do the job on the spot wherever possible, on your drive or at your workplace.
Codes cleared, warning off and the vehicle driving normally before we leave.
SCR efficiency and AdBlue quality codes that keep coming back.
"Starts remaining" messages before the vehicle locks out.

Upstream or downstream sensor errors and repeat warnings.
AdBlue will not dose, or freezes in winter.
Vehicles that never go on a UK public road.
Real fault codes from AdBlue systems we have diagnosed.

Yes. DEF (Diesel Exhaust Fluid) and AdBlue are the same urea solution used by the SCR system.
No. We make the change in the ECU software, which avoids the faults that plug-in emulators often cause.
Road vehicles must keep their emissions system working, so for those we repair the fault. A DEF bypass is for off-road, motorsport and export use.
Yes. We read and store your original ECU file before any changes, so the vehicle can be returned to standard.
We will diagnose the fault and quote for a proper repair. It is often less than people expect.
Yes. We are fully mobile across Stoke-on-Trent, Staffordshire and Cheshire.
Legal note: Removing or disabling emissions equipment on a vehicle used on UK public roads is not road legal and can lead to an MOT failure. AdBlue removal and delete work is supplied only for vehicles used off-road, in motorsport or for export. For any road vehicle we recommend an AdBlue repair, and we will always tell you which option fits how your vehicle is used.
