The “AdBlue System Fault” warning light on your Peugeot Boxer can be a stressful experience, but it doesn’t have to be a major headache. This article will guide you through the common causes of this warning, offer practical solutions, and explain how to reset the AdBlue system for a smooth driving experience.
What is AdBlue and Why Is It Important?
AdBlue is a urea-based fluid that’s added to your Peugeot Boxer’s exhaust system. It helps to reduce harmful nitrogen oxide (NOx) emissions, making your vehicle more environmentally friendly. The AdBlue system works by injecting the fluid into the exhaust stream, where it reacts with NOx to convert it into harmless nitrogen and water.
Common Reasons for a Peugeot Boxer AdBlue Warning Light
Here are some of the most frequent reasons for the AdBlue warning light to illuminate on your Peugeot Boxer:
- Low AdBlue Level: This is the most common reason. The AdBlue tank needs to be refilled periodically, just like your fuel tank.
- Faulty AdBlue Sensor: The sensor might be malfunctioning, giving a false reading about the AdBlue level.
- Clogged AdBlue Lines: The lines that carry AdBlue to the exhaust system can become blocked with debris, hindering the flow of fluid.
- Faulty AdBlue Pump: The pump responsible for injecting AdBlue into the exhaust might fail, preventing proper operation of the system.
- AdBlue Tank Problem: A leak in the AdBlue tank, a blocked vent, or other issues with the tank itself can lead to the warning light.
Troubleshooting the Peugeot Boxer AdBlue Warning Light
1. Check AdBlue Level and Refill if Needed:
- Locate the AdBlue tank in your Peugeot Boxer’s engine compartment.
- Use the dipstick or gauge to check the AdBlue level.
- If the level is low, refill the tank with certified AdBlue solution.
- Remember: Never use anything other than genuine AdBlue as it can damage your vehicle’s emissions system.
2. Reset the AdBlue System (If Applicable):
Sometimes, simply refilling the AdBlue tank might not be enough to clear the warning light. You may need to reset the AdBlue system.
Here’s a general guide:
- Turn the ignition to the “ON” position (but don’t start the engine).
- Find the AdBlue reset button. This button is often located near the steering wheel or on the dashboard.
- Press and hold the reset button for several seconds.
- Release the button.
- Start the engine and check if the warning light goes out.
Note: If the reset procedure doesn’t work, or you’re unsure how to do it, it’s best to consult your Peugeot Boxer’s user manual or contact a qualified mechanic.
3. Inspect AdBlue Lines for Blockages:
- Look for any visible blockages or damage in the AdBlue lines.
- If you find any problems, you may need to replace the damaged lines or clear the blockage.
4. Check the AdBlue Sensor:
- If you suspect a faulty sensor, consider having it checked by a mechanic. They can use diagnostic tools to assess the sensor’s functionality.
5. Examine the AdBlue Pump:
- If the pump is malfunctioning, it will need to be replaced by a qualified mechanic.
6. Inspect the AdBlue Tank:
- Look for any signs of leaks or damage to the tank.
- If you find any issues, you may need to repair or replace the tank.
