Removal and Requalification of AdBlue: Intervention and Restoration of the ECU

In this way, the vehicle will continue to operate according to the manufacturer’s regulations and specifications. During this period, the data collected will be useful for improving the vehicle's performance without compromising its compliance with emission standards.

The removal of AdBlue from a vehicle's ECU is an operation that involves various components of the emission control system. Here’s how it generally works:

Function of AdBlue: AdBlue is a urea-based solution used in diesel vehicles to reduce nitrogen oxide (NOx) emissions. It is injected into the exhaust system, where it reacts with exhaust gases to convert NOx into nitrogen and water.

Control Unit: The vehicle's electronic control unit (ECU) monitors and manages the AdBlue injection system, including the amount to be injected and the proper functioning of the system. This ECU receives information from various sensors, such as those measuring temperature, pressure, and AdBlue level.

Removal of AdBlue:

Software Modification: A technician can modify the ECU software to disable controls related to AdBlue. This may involve altering the operating parameters of the ECU so that it no longer detects the presence or level of AdBlue.
