The Citroen C4 Grand Picasso is a popular choice for families and commuters alike. However, like all vehicles, it can experience occasional issues. One such issue is the AdBlue system. If your Citroen C4 Grand Picasso is displaying AdBlue errors, it’s important to address the problem quickly. This guide will help you understand what causes AdBlue issues, how to reset the system, and when to seek professional assistance.
Understanding AdBlue and Its Importance
AdBlue is a urea-based solution that is injected into the exhaust system of diesel engines. It helps to reduce harmful nitrogen oxides (NOx) emissions, meeting strict environmental regulations. In the Citroen C4 Grand Picasso, AdBlue is stored in a dedicated tank, and the system automatically injects the appropriate amount during driving.

- AdBlue Tank Empty Warning: This is the most common AdBlue issue. It simply means the tank needs refilling. You can usually top up the tank with AdBlue solution purchased at most auto parts stores.
- AdBlue System Malfunction: This error message could indicate a problem with the AdBlue pump, injectors, or sensors. You may need to have the vehicle diagnosed by a qualified mechanic to determine the exact cause.
- AdBlue Quality Error: The AdBlue solution you’re using might not meet the required quality standards. Always use genuine AdBlue solution for your Citroen C4 Grand Picasso.
- AdBlue Heater Malfunction: The AdBlue heater ensures the solution stays at the correct temperature for optimal performance. If it malfunctions, you’ll need to address this issue.
Resetting the AdBlue System
If you are experiencing an AdBlue error, you may be able to reset the system yourself. Here’s a step-by-step guide:
- Ensure the AdBlue Tank is Full: Double-check that the AdBlue tank is full. If it’s not, top it up with genuine AdBlue solution.

Important Note: If the reset procedure doesn’t clear the AdBlue error, or if you’re unsure about any aspect of the process, it’s best to consult a qualified mechanic.
When to Seek Professional Help
While you can try resetting the AdBlue system yourself, it’s important to seek professional assistance if the problem persists. Here are some signs you should consult a mechanic:
