The AdBlue system in your Vivaro plays a crucial role in reducing harmful emissions. However, you might encounter problems like AdBlue warning lights, system malfunctions, or even complete failure. This guide will provide you with a step-by-step approach to understanding the AdBlue reset process, troubleshooting common problems, and getting back on the road without delay.
Understanding AdBlue and Its Importance
AdBlue is a urea-based solution that is injected into the exhaust system of your Vivaro. It breaks down harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor, meeting strict emission standards. When the AdBlue system malfunctions, it can trigger warning lights and potentially restrict engine performance.
Common Vivaro AdBlue Problems and Solutions
Here are some common AdBlue problems encountered by Vivaro owners:
1. AdBlue Warning Light
The AdBlue warning light indicates a low AdBlue level or a problem with the system.
Solution:
- Refill AdBlue: Check the AdBlue reservoir and refill it with the correct type of AdBlue.
- Reset the warning light: In most cases, the warning light will reset automatically after refilling the AdBlue. However, some Vivaro models might require a manual reset.
How to Manually Reset the AdBlue Warning Light:
- Consult your owner’s manual: Each Vivaro model might have a slightly different procedure for resetting the AdBlue warning light. Your owner’s manual will provide specific instructions.
- Use a diagnostic tool: If you can’t find the instructions in your owner’s manual, you can use a diagnostic tool to reset the warning light.
- Contact a mechanic: If the warning light persists after refilling and resetting, it’s recommended to consult a mechanic.
2. AdBlue System Malfunction
The AdBlue system can malfunction due to various reasons, such as faulty sensors, clogged lines, or a defective control unit.
Solution:
- Check AdBlue lines and sensors: Inspect the AdBlue lines for any leaks or clogs. Check the AdBlue level sensor for proper function.
- Diagnose with a scan tool: Utilize a scan tool to identify specific fault codes related to the AdBlue system. These codes will help you pinpoint the source of the problem.
- Consult a mechanic: If the problem persists after diagnosing, it’s advisable to take your Vivaro to a qualified mechanic for professional diagnosis and repair.
3. AdBlue Pump Failure
The AdBlue pump is responsible for delivering the solution into the exhaust system. If the pump fails, it can cause the AdBlue system to stop working.
Solution:
- Replace the pump: If the AdBlue pump fails, you’ll need to replace it with a new one. This requires professional assistance and a specialized tool.
- Check for related issues: While replacing the pump, it’s essential to inspect the AdBlue lines and sensors to ensure they are in good condition.
When to Consider a Professional AdBlue Reset
In some cases, a simple reset might not be enough to fix the AdBlue system. Here are a few scenarios where professional help is recommended:
- Frequent warning light: If the AdBlue warning light appears frequently even after refilling the AdBlue, it indicates an underlying issue that needs attention.
- Engine performance issues: If your Vivaro is experiencing reduced engine performance or power loss, it could be related to the AdBlue system.
- Complex diagnostic codes: If the scan tool displays complex fault codes that you can’t interpret or resolve, a mechanic can provide a more in-depth diagnosis.
- Physical damage: Any visible damage to the AdBlue system, such as leaks, broken lines, or damaged sensors, should be addressed by a qualified professional.
Avoiding AdBlue Issues in the Future
- Use high-quality AdBlue: Using the correct type of AdBlue is essential for optimal system performance.
- Regularly check AdBlue level: Monitor the AdBlue level regularly and refill it before it gets too low.
- Schedule regular maintenance: Follow the recommended maintenance schedule for your Vivaro, which includes checks on the AdBlue system.
- Avoid refilling with contaminated AdBlue: Always ensure that the AdBlue you use is clean and uncontaminated.
Conclusion
The AdBlue system in your Vivaro plays a crucial role in reducing emissions. Understanding common AdBlue problems and solutions is essential for maintaining optimal performance and avoiding potential issues. While basic troubleshooting can be done at home, consulting a qualified mechanic is recommended for complex problems or if you’re unsure about any aspect of the AdBlue system. Remember, taking care of your Vivaro’s AdBlue system will contribute to a smoother driving experience and a more environmentally friendly journey.
