The AdBlue system failure it's a common problem in modern diesel vehicles equipped with technology SCR (Selective Catalytic Reduction). This system is designed to reduce the engine's harmful emissions, but when it malfunctions, it can cause dashboard warnings, loss of power, or even prevent the vehicle from starting.
At our workshop, we offer professional solution for AdBlue system faults, performing advanced diagnostics and specialized repairs to restore the correct functioning of the emissions system.
What is an AdBlue fault?
A AdBlue fault it occurs when one of the SCR system components stops working correctly, or when the vehicle's electronic control unit detects a fault in the emissions control system.
When this happens, the vehicle may activate warnings such as:
- AdBlue or emissions system warning light on
- Error messages on the dashboard
- Avisos de “fallo del sistema SCR”
- Kilometer countdown until start-up lockout
These warnings indicate that the vehicle needs AdBlue system diagnosis and repair.
Symptoms of AdBlue System Problems
SCR system failures can manifest in different ways depending on the type of fault.
Among the most common symptoms are:
- AdBlue warning on the dashboard
- Loss of engine power
- Vehicle performance limitation
- Emissions-related error messages
- Inability to start the vehicle after a certain mileage
Detecting the problem early allows avoid major damage to the emissions system.
Main causes of AdBlue failures
Faulty NOx sensor
NOx sensors measure engine emissions. When they fail, the SCR system detects incorrect values and triggers an AdBlue system fault.
Clogged AdBlue injector
Over time, AdBlue can crystallize within the system, causing obstructions in the injector responsible for spraying the liquid into the exhaust.
AdBlue pump failures
The pump is responsible for transporting the fluid from the reservoir to the injection system. If it fails, the system cannot correctly perform the emissions reduction process.
AdBlue tank problems
The tank may develop faults such as:
- Defective level sensor
- Liquid crystallization
- Heating system problems
Electronic failures of the SCR system
In some cases, the problem might be related to errors in the emissions system control unit, which requires specialised electronic diagnostics.
Our AdBlue fault resolution service
In our workshop, we have professional diagnostic equipment capable of analyzing the SCR system and accurately detecting faults in the AdBlue system.
Our service includes:
- Advanced electronic diagnostics
- Reading and interpretation of error codes
- NOx sensor inspection
- AdBlue injector and pump inspection
- Tank and SCR system check
- System crystallization removal
This process allows us to identify the exact cause of the fault and apply the appropriate repair.
Professional AdBlue system repair
Once the source of the problem is identified, we carry out the necessary repairs to restore the system's functionality.
Solutions may include:
- AdBlue system cleaning
- Injector repair or replacement
- NOx sensor replacement
- Repair of pump or tank
- Electronic remapping of the system
Our goal is remove the AdBlue system fault and prevent it from reappearing.
