What is the AdBlue system?

AdBlue is a system used to reduce NOx emissions in diesel vehicles. The AdBlue fluid is stored in a separate tank and injected into the exhaust system upstream of an SCR catalyst. While this method is effective for emissions control, it requires regular refilling of the AdBlue tank, which can become costly over time.

AdBlue System Faults

When AdBlue related faults occur, such as low fluid levels, sensor failures, or system malfunctions, modern vehicles often display warning messages, activate countdown timers limiting how far you can drive, and eventually prevent the engine from starting altogether.

What is AdBlue Removal?

AdBlue removal is a software-based solution that disables the AdBlue system (also known as SCR — Selective Catalytic Reduction) within a vehicle’s ECU. This allows the vehicle to operate normally without requiring AdBlue fluid, and without any of the usual faults or restrictions associated with a failing AdBlue system.

The law regarding AdBlue removal.

If you are located outside of the UK, please check your local laws. For UK customers and installers, Under the Road Vehicles (Construction and Use) Regulations and the Road Traffic Act 1988 it is an offence to use on a road a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was originally designed to meet. Removal of emissions control devices is intended to support motorsport and off-road applications.

Further information on the UK law can be found on the UK government website here.
