FixDeviceProblems.comDefects of the AdBlue tank on the Peugeot 308: impacts and solutions
The AdBlue tank is a key component of the modern diesel engine depollution system, and on the Peugeot 308, it plays a crucial role in meeting environmental standards. However, like any automotive component, issues can arise, impacting the vehicle's performance and requiring appropriate solutions. In this article, we will examine the common defects of the AdBlue tank on the Peugeot 308, their impacts on the car, and possible solutions to resolve these problems.
The role of the AdBlue tank in the Peugeot 308
The AdBlue tank of the Peugeot 308 is an integral part of the SCR (Selective Catalytic Reduction) system, allowing for effective reduction of nitrogen oxide (NOx) emissions. This technology has become essential to meet Euro 6 standards, and the AdBlue tank stores a urea-based solution that is injected into the exhaust system to treat exhaust gases before they are released into the atmosphere.
Common defects of the AdBlue tank on the Peugeot 308
1. Leak in the AdBlue tank
A leak in the AdBlue tank can lead to a loss of the solution necessary for the proper functioning of the SCR system. This issue is often caused by cracks or faulty seals. A leak can result in excessive AdBlue consumption, or even engine malfunction if the tank becomes too empty.
2. Failure of the AdBlue level sensor
The AdBlue level sensor is a device that monitors the amount of solution in the tank. If this sensor fails, it can distort the indicators on the dashboard, giving the impression that the tank is full or empty. This can create a situation where the driver finds themselves without AdBlue with no prior warning.
3. Blockage of the AdBlue distribution system
Another common issue is the blockage of the AdBlue distribution system, often due to the accumulation of crystals in the pipes or pump. This blockage prevents AdBlue from being injected properly into the exhaust system, which can lead to increased pollutant emissions and a warning on the dashboard.
The impacts of defects in the AdBlue tank on the Peugeot 308
1. Increase in pollutant emissions
When the SCR system does not function properly due to an issue with the AdBlue tank, NOx emissions increase, which harms the environmental performance of the car. This can also result in non-compliance with Euro 6 standards, which can be problematic during technical inspections.
2. Engine performance issues
A defective AdBlue tank can lead to a limitation of engine power. The vehicle may enter "performance limitation" mode, a safety measure to prevent engine damage. This results in less smooth driving and a significant loss of power.
3. Risk of mechanical failure
In the event of a complete failure of the AdBlue tank, the car may stop completely, preventing any start or leading to severe mechanical failure. This type of failure requires immediate intervention to prevent further damage to the vehicle.
Solutions for defects in the AdBlue tank of the Peugeot 308
1. Replacement or repair of the AdBlue tank
If the tank has a leak, replacing the tank is often necessary. Depending on the severity of the leak, a repair may suffice, but it is essential to ensure the tank's tightness to avoid any loss of AdBlue and ensure optimal operation of the SCR system.
2. Replacement of the AdBlue level sensor
In case of a failure of the level sensor, it is often simpler and more economical to replace it. This allows for accurate AdBlue level readings and avoids false alerts.
3. Maintenance of the AdBlue distribution system
To prevent clogs, it is essential to regularly maintain the AdBlue distribution system, particularly by checking the pump and pipes to ensure that no crystal buildup occurs. Periodic cleaning or flushing can extend the lifespan of the system.
4. Use quality AdBlue
To prevent crystallization and blockage issues, it is important to use quality AdBlue that meets ISO 22241 standards. This ensures that the solution does not contain impurities that could damage the tank or the SCR system of the Peugeot 308.
Conclusion: Ensure the maintenance of the AdBlue tank in your Peugeot 308
In summary, although the AdBlue tank of the Peugeot 308 is an essential component for meeting environmental standards, it can be subject to certain defects that may impact vehicle performance. By ensuring regular maintenance and promptly addressing any issues that arise, you can extend the lifespan of your vehicle and maintain its performance at an optimal level.
