AdBlue / SCR Delete

Permanent ECU software solution to disable the AdBlue (SCR) system. Eliminate AdBlue warning lights, injector failures, and costly top-ups.

AdBlue (also known as DEF — Diesel Exhaust Fluid) is a urea-based solution injected into the exhaust system of Euro 5 and Euro 6 diesel vehicles to reduce NOx emissions. While the system works well when new, AdBlue components are notoriously unreliable — the injector, pump, level sensor, and NOx sensors are all common failure points. A faulty AdBlue system will trigger warning lights and, if ignored, prevent the engine from starting entirely. LutonRemap offers a complete ECU software solution that permanently disables the AdBlue/SCR system, eliminating all associated fault codes and warnings.

Common AdBlue Problems

  • •AdBlue level warning — vehicle will not start after countdown reaches zero
  • •AdBlue injector failure — crystallisation blocks the injector nozzle
  • •AdBlue pump failure — common on high-mileage vehicles
  • •NOx sensor failure — triggers fault codes and limp mode
  • •AdBlue quality warning — system rejects fluid due to contamination
  • •SCR catalyst failure — extremely expensive to replace

How We Disable AdBlue

We connect to your ECU and modify the SCR/AdBlue control maps, disabling all monitoring, dosing, and fault-triggering logic. The system is completely neutralised in software — no physical components need to be removed. All related fault codes are cleared and suppressed permanently.

Compatible Vehicles

AdBlue delete is available for all Euro 5 and Euro 6 diesel vehicles including VW Group, BMW, Mercedes, Ford, Vauxhall, Renault, Peugeot, Citroën, Volvo, DAF, MAN, Iveco, and more.

Legal Notice: AdBlue/SCR deletion is intended for off-road, agricultural, and export use only. It is illegal to use an AdBlue-deleted vehicle on UK public roads. The customer is solely responsible for compliance with applicable regulations.

Key Benefits

  • Eliminates all AdBlue warning lights and fault codes
  • Prevents engine start lockout caused by empty or faulty AdBlue system
  • No more AdBlue top-ups (typically every 5,000–8,000 miles)
  • Removes risk of expensive injector and pump failures
  • Saves hundreds of pounds in AdBlue system repairs
  • Fully software-based — no physical components removed
  • Suitable for off-road, agricultural, and export vehicles

Frequently Asked Questions

My AdBlue warning says I have X miles left — can you fix it before it locks out?+

Yes. We can disable the AdBlue system at any point before or after the countdown. Even if the vehicle has already locked out, we can resolve it via ECU modification.

Will AdBlue off affect engine performance?+

No negative effect on performance. In some cases there is a slight improvement as the ECU no longer has to manage the SCR dosing strategy.

Is the fix reversible?+

Yes. We always save the original ECU map and can restore the AdBlue system to factory settings at any time.

Does it work on vans and trucks?+

Yes — we cover light commercial vehicles (LCVs) such as Ford Transit, VW Crafter, Mercedes Sprinter, as well as HGVs and agricultural machinery.
