Your Peugeot Expert AdBlue warning light is on, and you’re wondering what to do next. This is a common issue that can cause stress for any vehicle owner, but don’t panic! This guide will help you understand the causes of the AdBlue warning light, explore potential solutions, and guide you through resetting the system if needed.
What is AdBlue?
AdBlue is a solution of urea and deionized water that is injected into the exhaust system of diesel vehicles to reduce nitrogen oxide (NOx) emissions. It’s a crucial part of modern diesel engines, ensuring they meet strict environmental regulations.
Why is My Peugeot Expert AdBlue Warning Light On?
There are a few reasons why your AdBlue warning light might be illuminated:
- Low AdBlue Level: The most common reason is simply that your AdBlue tank is running low. Your Peugeot Expert has a sensor that monitors the AdBlue level and triggers the warning light when it reaches a certain threshold.
- AdBlue System Malfunction: There could be an issue with the AdBlue system itself, including a faulty sensor, a clogged nozzle, or a problem with the pump.
- AdBlue Quality Issues: Using low-quality AdBlue can lead to problems, as it may not be compatible with your vehicle’s system.
- Incorrect AdBlue Filling: Incorrectly filling the AdBlue tank can cause problems, such as air pockets or contamination.
What to Do When the AdBlue Warning Light is On
- Check the AdBlue Level: First, ensure the AdBlue level is low by checking the gauge on your dashboard or using the dipstick in the AdBlue tank. If it’s low, top up the tank with high-quality AdBlue.
- Drive Carefully: If the AdBlue level is low, you can drive your vehicle for a short distance while topping up. However, you should avoid long journeys and high speeds, as this can increase the risk of engine damage.
- Professional Inspection: If the AdBlue warning light stays on even after topping up the tank, you need to have your vehicle inspected by a qualified mechanic. They can diagnose the problem and recommend the appropriate solution.
Can I Reset the AdBlue Warning Light Myself?
In some cases, you might be able to reset the AdBlue warning light yourself. However, it’s essential to understand the risks involved. If the underlying issue isn’t addressed, resetting the warning light might only temporarily mask the problem.
Here’s a common method for resetting the AdBlue warning light:
- Turn the ignition to the “ON” position without starting the engine.
- Press the accelerator pedal three times in quick succession.
- Turn the ignition off.
- Start the engine.
Important: This method may not work on all Peugeot Expert models, and it’s vital to consult your owner’s manual for specific instructions for your vehicle.
Common AdBlue Problems and Solutions
AdBlue System Malfunction:
- Faulty Sensor: A faulty sensor can trigger the AdBlue warning light even if there’s enough AdBlue in the tank. A qualified mechanic will need to diagnose and replace the faulty sensor.
- Clogged Nozzle: A clogged AdBlue nozzle can prevent the solution from reaching the exhaust system properly. This can be cleaned or replaced by a mechanic.
- Pump Failure: An AdBlue pump failure can prevent the solution from being delivered to the exhaust system. A mechanic will need to diagnose and repair or replace the pump.
AdBlue Quality Issues:
- Using Incorrect AdBlue: Always ensure you’re using the correct type of AdBlue for your vehicle. Using a different type can lead to compatibility issues and damage the system.
- Contaminated AdBlue: Contaminated AdBlue can also cause problems. Use high-quality AdBlue from a reputable source.
Incorrect AdBlue Filling:
- Air Pockets: If the AdBlue tank is not filled properly, air pockets can form, leading to system problems.
- Contamination: Filling the AdBlue tank with contaminated fluids can lead to system failure. Always use clean, high-quality AdBlue.
AdBlue System Maintenance Tips
Here are a few tips to help you avoid AdBlue-related problems:
- Regularly Check AdBlue Level: Check the AdBlue level regularly to ensure you don’t run out.
- Use High-Quality AdBlue: Always use high-quality AdBlue from a reputable source.
- Avoid Contaminating the AdBlue Tank: Only use a clean funnel and avoid spilling any other fluids into the AdBlue tank.
