The AdBlue system plays a vital role in reducing nitrogen oxide (NOx) emissions in diesel vehicles, ensuring compliance with environmental regulations. Proper maintenance of your AdBlue system is essential to prevent costly repairs, improve fuel efficiency, and extend the lifespan of your vehicle’s Selective Catalytic Reduction (SCR) system.
Star Garage Mansfield offers expert AdBlue solutions, including AdBlue repair services for diesel vehicles. Their specialists ensure efficient AdBlue system maintenance, helping reduce emissions and keep your vehicle compliant with environmental standards.
At Star Garage Mansfield, we specialize in AdBlue solutions, providing expert maintenance and repair services to keep your system in top condition. In this guide, we will explore the best practices for AdBlue system maintenance, helping you avoid common issues and ensuring optimal performance.
Understanding the AdBlue System
AdBlue is a high-purity urea-based fluid that is injected into the exhaust system of diesel vehicles equipped with SCR technology. When heated, AdBlue breaks down into ammonia, which reacts with NOx emissions, converting them into harmless nitrogen and water vapor.
A well-maintained AdBlue system ensures:
Compliance with Euro 6 emissions standards
Reduced NOx emissions for a cleaner environment
Improved fuel efficiency and engine performance
Prevention of costly AdBlue repair issues
Key Steps to Maintain Your AdBlue System
1. Regularly Check AdBlue Levels
One of the simplest yet most important maintenance tasks is to monitor your AdBlue levels regularly. Running out of AdBlue can cause:
The vehicle to enter limp mode, reducing engine power
Activation of dashboard warning lights
Failure to start in some cases
Most vehicles provide a low AdBlue warning when the fluid level drops, but it's best to refill before the warning appears.
2. Use High-Quality AdBlue Fluid
Always use ISO 22241-certified AdBlue to ensure purity and prevent contamination. Low-quality or counterfeit AdBlue solutions can:
Damage the SCR system
Cause injector blockages
Lead to increased repair costs
At Star Garage Mansfield, we supply premium AdBlue solutions that meet the highest industry standards.
3. Store AdBlue Properly
Proper storage of AdBlue is essential to maintain its effectiveness. Follow these guidelines:
Store AdBlue in a cool, dry place away from direct sunlight
Keep it in sealed containers to prevent contamination
Avoid storing AdBlue in extreme temperatures (below -11°C or above 30°C)
Improper storage can degrade the fluid, reducing its effectiveness and causing SCR system issues.
4. Inspect for Crystallization and Deposits
Crystallization occurs when AdBlue dries and leaves solid deposits around the injector or supply lines. This can lead to:
Injector blockages
Reduced AdBlue injection efficiency
Increased NOx emissions
Regularly inspect AdBlue injectors and supply lines for crystallization and clean them if necessary. If the problem persists, professional servicing may be required.
5. Avoid Contaminating the AdBlue Tank
Contamination is one of the leading causes of AdBlue system failure. To prevent contamination:
Never mix AdBlue with water, fuel, or other fluids
Use a clean funnel or pump when refilling
Ensure the AdBlue cap is securely closed after filling
If contamination occurs, the entire system may need flushing to remove impurities.
6. Check for Leaks in the AdBlue System
Leaks in the AdBlue tank or supply lines can cause:
Rapid fluid loss
Inefficient NOx reduction
Dashboard warning lights
Inspect the AdBlue tank, hoses, and injector seals for cracks or loose connections. If you notice a leak, have it repaired immediately.
7. Perform Regular AdBlue System Diagnostics
Modern vehicles store AdBlue system fault codes that can be checked using an OBD-II scanner. Some common fault codes include:
P20EE – SCR system efficiency below threshold
P207F – Reductant quality performance issue
P204F – Reductant system malfunction
If your vehicle displays any AdBlue-related fault codes, seek professional diagnostics and repair services at Star Garage Mansfield.
8. Clean or Replace the AdBlue Injector When Necessary
The AdBlue injector is responsible for spraying the fluid into the exhaust system. Over time, it may become clogged due to crystallization or contamination. Cleaning or replacing the AdBlue injector ensures proper function and prevents:
Inefficient fluid distribution
Increased NOx emissions
SCR system failure
9. Flush the AdBlue System Periodically
Over time, impurities can build up in the AdBlue system, leading to performance issues. A periodic AdBlue system flush can:
Remove contaminants and prevent injector blockages
Improve overall system efficiency
Extend the life of the SCR system
At Star Garage Mansfield, we offer professional AdBlue flushing services to keep your system in optimal condition.
10. Reset the AdBlue System After Servicing
After refilling AdBlue or performing repairs, some vehicles require a system reset. If the AdBlue warning light remains on after a refill, a reset using a diagnostic tool may be necessary. Our experts at Star Garage Mansfield can perform a full system reset to ensure proper function.
Common Mistakes to Avoid When Maintaining Your AdBlue System
To prevent AdBlue-related issues, avoid these common mistakes:
Using Water Instead of AdBlue – Water cannot replace AdBlue and will damage the SCR system.
Mixing Different AdBlue Brands – Stick to a trusted supplier to ensure consistent quality.
Overfilling the AdBlue Tank – This can cause spills and crystallization.
Ignoring the AdBlue Warning Light – Running out of AdBlue can trigger limp mode, restricting vehicle performance.
