How does an SCR AdBlue system work?
An SCR AdBlue system works by injecting a small amount of AdBlue solution into the exhaust stream. When this solution is heated, it breaks down into ammonia (NH3) and carbon dioxide (CO2). The ammonia then reacts with NOx in the exhaust, converting it into harmless nitrogen (N2) and water (H2O).
The AdBlue solution is stored in a separate tank and is typically replenished during routine maintenance. The injection of AdBlue into the exhaust stream is controlled by a dosing module, which receives signals from the engine control unit (ECU) to determine the proper amount of AdBlue to inject.

Symptoms of a malfunctioning SCR AdBlue system
If the SCR AdBlue system is not functioning properly, there are several symptoms that may indicate an issue. One common symptom is a warning light on the dashboard, which may indicate a fault with the AdBlue system. Other symptoms may include decreased engine performance, increased emissions, or even engine shutdown in severe cases.
Fault codes associated with SCR AdBlue systems
When an SCR AdBlue system malfunctions, it may trigger one or more fault codes that can help diagnose the issue. Some of the most common fault codes associated with AdBlue systems include:

Fault codes associated with SCR AdBlue systems
When an SCR AdBlue system malfunctions, it may trigger one or more fault codes that can help diagnose the issue. Some of the most common fault codes associated with AdBlue systems include:
- P20EE: This code indicates a malfunction in the AdBlue system, often caused by a faulty AdBlue pump or injector.
- P204F: This code indicates a malfunction in the Reductant System Performance, often caused by a clogged injector or low AdBlue levels.
- P229F: This code indicates a fault with the diesel exhaust fluid (DEF) pressure sensor, which may cause the AdBlue system to malfunction
