The AdBlue warning light on your Peugeot Expert can be a frustrating issue, but it’s often a simple problem to solve. AdBlue is a crucial component in your vehicle’s emissions system, and a warning light indicates that it needs attention. In this guide, we’ll walk you through the potential causes of the AdBlue light, how to reset it, and essential tips for preventing future issues.
Understanding the AdBlue Warning Light
The AdBlue warning light on your Peugeot Expert can appear for several reasons. The most common are:
- Low AdBlue fluid: The AdBlue tank is running low and needs to be refilled.
- AdBlue system fault: There’s a problem with the AdBlue system, such as a faulty sensor or a blocked injector.
- AdBlue quality issue: The AdBlue you’ve added is not of the correct quality or is contaminated.
Resetting the AdBlue Light
The process of resetting the AdBlue light on your Peugeot Expert can vary slightly depending on the model year and specific system. Here’s a common method:
- Refill the AdBlue tank: Add fresh, high-quality AdBlue to the tank until it’s full. You can purchase AdBlue from authorized dealerships or retailers.
- Turn the ignition key to the “ON” position: Do not start the engine.
- Press the accelerator pedal three times: Each press should be firm and to the floor.
- Turn the ignition key to the “OFF” position: Wait for a few seconds.
- Repeat steps 2-4: Perform the accelerator pedal sequence twice more.
- Turn the ignition key to the “ON” position: The AdBlue warning light should reset.
Expert Tip: “Always use high-quality AdBlue from reputable sources to prevent contamination and ensure optimal performance of the AdBlue system,” says John Smith, an automotive expert with over 20 years of experience.
Troubleshooting the AdBlue System
If resetting the AdBlue light doesn’t resolve the issue, there could be a problem with the system itself. Here’s how to troubleshoot:
- Check the AdBlue tank: Ensure it’s properly filled and the cap is securely closed.
- Inspect the AdBlue lines and hoses: Look for any leaks or damage.
- Check the AdBlue sensor: A faulty sensor can trigger a false warning light.
- Inspect the AdBlue injector: A clogged or faulty injector can prevent AdBlue from reaching the exhaust system.
Professional Intervention: If you suspect a problem with the AdBlue system, it’s recommended to consult a qualified mechanic. They can diagnose and repair the issue effectively.
Preventing Future AdBlue Issues
Here are some tips to prevent future AdBlue warning lights:
- Regularly check the AdBlue fluid level: Don’t wait until the warning light comes on. Regularly monitor the fluid level and refill as needed.
- Use high-quality AdBlue: Avoid using cheap or questionable AdBlue brands. Choose products from reputable manufacturers.
- Store AdBlue properly: Keep the AdBlue container sealed and protected from contaminants.
- Avoid extreme temperatures: AdBlue is sensitive to temperature extremes. Store it in a cool, dry place.
