A typical AdBlue® system consists of several components

• AdBlue Tank: This is where the AdBlue fluid is stored in the vehicle.
• AdBlue Filler Cap: A dedicated filler cap for adding AdBlue to the tank.
• AdBlue Pump: A pump is used to transfer AdBlue from the tank to the dosing module.
• Dosing Module: This component precisely injects the correct amount of AdBlue into the exhaust system to react with harmful emissions.
• AdBlue Injector: The injector sprays AdBlue into the exhaust stream to facilitate the selective catalytic reduction (SCR) process.
• SCR Catalyst: A catalyst that helps in reducing harmful nitrogen oxide (NOx) emissions by reacting with AdBlue.
• AdBlue Sensors: These sensors monitor the AdBlue level, quality, and other parameters to ensure proper system operation.
• AdBlue Lines and Hoses: Various hoses and lines connect the components and allow the flow of AdBlue.
• Control Unit: A control unit or Electronic Control Module (ECM) manages the AdBlue system's operation and communication with the vehicle's engine control unit.

These are the primary components of a typical AdBlue system in a vehicle, and they work together to reduce harmful emissions and comply with emissions standards.

When a vehicle with AdBlue ® displays an engine warning light and or a mileage countdown to non start state the first thing to check is that there is enough AdBlue in the tank.

Once you have topped up if required and you still have the countdown and engine light it is important to immediately have it dealt with, as the countdown can be erratic and catch you out unexpectedly.

For example, we have calls from people with 700 mile to non-start countdown who put off the inevitable, the countdown can randomly drop overnight and or in between ignition cycles leaving owners with a non-starting vehicle.

The challenge of diagnosing an AdBlue issue is that a diagnostic tool however good can indicate a component fault that turns out to be a phantom fault.

What do we mean about phantom faults?
Simply put the diagnostic tool isn’t the silver bullet or magical solution most people think it is, and simply resetting the fault codes is no more than a very short-term reprieve.

When an AdBlue system fails, it can often lead to long wait times (for even an inspection by your main dealer) and then an expensive parts replacement process until the correct faulty part is identified and replaced.

Meanwhile, you can be left without your essential daily vehicle, we can help in this event.
