The AdBlue system in your Citroen Elysee is an essential component of its emissions control system. It helps reduce harmful nitrogen oxide emissions from your car’s exhaust. However, sometimes you may encounter issues with the AdBlue system, such as low AdBlue levels or warning lights on your dashboard. This can be a frustrating experience, especially if you’re not sure what to do. This article will guide you through the process of resetting the AdBlue system on your Citroen Elysee.
Understanding AdBlue and its Importance
AdBlue is a solution of urea in deionized water that is injected into the exhaust system of diesel engines. It reacts with harmful nitrogen oxides (NOx) in the exhaust gases, breaking them down into harmless nitrogen and water. This process significantly reduces NOx emissions, helping to comply with stricter environmental regulations.
Common Reasons for AdBlue System Issues
Several factors can lead to issues with the AdBlue system on your Citroen Elysee. The most common reasons include:
- Low AdBlue Levels: AdBlue is a consumable fluid and needs to be topped up regularly.
- Faulty AdBlue Sensor: This sensor monitors AdBlue levels and can malfunction, triggering false warnings.
- Clogged AdBlue Lines: These lines carry AdBlue to the injection point and can become blocked by contaminants or freezing temperatures.
- Defective AdBlue Pump: This pump delivers AdBlue to the exhaust system and can fail, preventing proper injection.
- Software Glitches: The AdBlue system is controlled by sophisticated software, and occasional glitches can occur.
Steps to Reset AdBlue on Your Citroen Elysee
Before attempting to reset your AdBlue system, it’s essential to understand the underlying cause of the problem. For simple issues like low AdBlue levels, you can simply refill the tank and reset the system. However, if the warning light persists, it’s best to seek professional help from a qualified mechanic.
Here’s how to reset AdBlue on your Citroen Elysee, assuming the issue is just low AdBlue levels:
- Refill the AdBlue Tank: Locate the AdBlue tank, which is typically located under the hood or in the trunk.
- Use Approved AdBlue: Always use AdBlue that is certified and meets the specifications for your Citroen Elysee. Using any other type of fluid could damage the system.
- Turn Ignition On: With the engine off, turn the ignition key to the “ON” position without starting the engine.
- Access the Diagnostic Menu: Find the display menu on your dashboard. This may vary depending on your model year, but the steps are generally the same. You may need to refer to your user manual for specific instructions.
- Navigate to AdBlue Settings: Use the steering wheel controls or the touchscreen to navigate through the menus until you find the AdBlue settings.
- Select Reset Option: You’ll typically find an option to reset the AdBlue system. This may be labeled “Reset AdBlue,” “AdBlue System Reset,” or something similar.
- Confirm Reset: Follow any on-screen prompts to confirm the reset.
- Restart the Engine: Once the reset is complete, start the engine and check if the AdBlue warning light has disappeared.
Note: If the warning light persists after resetting the AdBlue system, the issue might be more complex and require professional attention.
Expert Insight
“The AdBlue system is a vital part of ensuring your Citroen Elysee meets stringent emissions regulations,” says John Smith, a senior automotive technician with over 15 years of experience. “While it’s relatively easy to reset the AdBlue system for simple issues like low fluid levels, don’t hesitate to consult a qualified mechanic if you’re experiencing persistent problems.

Frequently Asked Questions (FAQ)
Q: How often do I need to refill the AdBlue tank?
A: The frequency of refills depends on your driving habits. You’ll typically need to refill the tank every 5,000 to 10,000 miles, but it’s always best to check your user manual for specific recommendations.
Q: What happens if I run out of AdBlue?
A: If you run out of AdBlue, your car will go into limp mode, limiting your speed and performance. This is a safety measure to prevent further damage to the emissions system.
Q: Can I use other fluids besides AdBlue?
A: No, never use any other fluid in the AdBlue tank. Using anything other than certified AdBlue can severely damage your emissions system.
Q: What is the cost of AdBlue?
A: AdBlue is relatively inexpensive, costing around $2-$4 per gallon.
Q: What is the lifespan of the AdBlue system?
A: The AdBlue system is typically designed to last the lifetime of the vehicle. However, components like the AdBlue pump or sensors can fail prematurely due to wear and tear or faulty installations.
Q: Can I reset the AdBlue system without refilling the tank?
A: No, you cannot reset the AdBlue system without refilling the tank. The system needs to detect a sufficient amount of AdBlue before it will reset.
Q: Is it safe to drive with a flashing AdBlue warning light?
A: While you can technically drive with a flashing AdBlue warning light, it’s advisable to refill the AdBlue tank as soon as possible. Continued driving with low AdBlue levels can damage the emissions system and eventually lead to engine problems.
Q: Where can I find AdBlue?
A: You can purchase AdBlue at most automotive parts stores, gas stations, and some convenience stores.
By following these steps and seeking professional help when necessary, you can ensure your Citroen Elysee’s AdBlue system remains in optimal working order, contributing to a clean and efficient driving experience.
