The AdBlue system is a vital part of modern diesel vehicles, helping to reduce harmful nitrogen oxide (NOx) emissions. It’s common for drivers of the 2018 Citroen Dispatch to encounter AdBlue system problems that require resetting. This article will guide you through the process of resetting your 2018 Citroen Dispatch’s AdBlue system, providing detailed instructions and troubleshooting tips.
Understanding AdBlue and Its Role in Your Citroen Dispatch
AdBlue is a non-toxic urea solution that is injected into the exhaust system of your Citroen Dispatch. When heated, it breaks down into ammonia, which then reacts with NOx in the exhaust gases, converting them into harmless nitrogen and water. This process significantly reduces the harmful emissions from your vehicle.
The AdBlue system in your Citroen Dispatch has a specific tank that needs to be regularly refilled. If the AdBlue level falls below a certain threshold, your vehicle will display a warning message on the dashboard.
Why Resetting Your AdBlue System is Necessary
Resetting the AdBlue system on your 2018 Citroen Dispatch is often necessary in situations like:
- AdBlue level warning: When the AdBlue tank is low, your Citroen Dispatch will display a warning message, and the system may require resetting after refilling the tank.
- Faulty sensor: If the AdBlue sensor malfunctions, it can trigger false warnings, requiring a reset to recalibrate the system.
- After a repair: In case of repairs or maintenance involving the AdBlue system, resetting may be necessary to ensure the system operates correctly.
- Software update: After receiving a software update for the vehicle’s ECU, resetting the AdBlue system might be recommended.
How to Reset the AdBlue System on Your 2018 Citroen Dispatch
Here’s a step-by-step guide on how to reset the AdBlue system on your 2018 Citroen Dispatch:
- Fill the AdBlue tank: Ensure the AdBlue tank is filled with the correct solution. If the tank is low, it’s essential to top it off.
- Turn on the ignition: Make sure the engine is off, but the ignition is turned on.
- Access the vehicle’s menu: Use the steering wheel controls or the touchscreen display to navigate to the vehicle’s settings menu.
- Locate the AdBlue settings: Search for the AdBlue settings within the menu. You may need to scroll through different options.
- Select the “Reset” option: The AdBlue settings will usually have an option to reset the system. Choose that option.
- Confirm the reset: The system may ask you to confirm the reset action. Confirm the process to begin the reset.
- Wait for the reset to complete: The reset process can take a few minutes. Avoid turning off the ignition or restarting the engine during this time.

Common AdBlue Problems and Troubleshooting Tips
Even after resetting the system, you may still encounter AdBlue issues. Here are some common problems and troubleshooting tips:
- Incorrect AdBlue solution: Ensure you are using the correct AdBlue solution. Using an incorrect fluid can cause damage to the system.
- Clogged AdBlue lines: If the lines are clogged, the solution won’t reach the exhaust system. Check for blockages and clear them if necessary.
- Faulty sensor: A faulty sensor can provide inaccurate readings, triggering false warnings. If you suspect a sensor issue, consult a mechanic for a proper diagnosis.
- Software malfunction: A software glitch in the vehicle’s ECU can also cause AdBlue problems. Contact your Citroen dealer or a qualified mechanic to troubleshoot software issues.
