Your Peugeot Partner’s AdBlue warning light is flashing, and you’re unsure what to do. It’s a common problem, and it can be frustrating to deal with. This guide will explain everything you need to know about this issue, from the causes to potential solutions and how to reset the warning light.
What is AdBlue?
AdBlue is a solution of urea and deionized water that’s injected into the exhaust system of diesel engines. It helps reduce harmful emissions like nitrogen oxides (NOx) by converting them into harmless nitrogen and water. It’s an essential part of modern diesel vehicles that meet Euro 6 and later emission standards.
Why is the AdBlue Warning Light On?
The AdBlue warning light on your Peugeot Partner can illuminate for various reasons:
Low AdBlue Fluid Level
The most common reason for the AdBlue warning light is simply a low fluid level in the tank. This could be due to:
- Not topping up the AdBlue regularly: AdBlue needs to be topped up at regular intervals, and neglecting this can lead to a low level.
- Leaking AdBlue tank: A cracked or damaged AdBlue tank can cause leaks, leading to a lower fluid level.
- Faulty AdBlue sensor: The sensor that monitors the AdBlue level might be malfunctioning, giving a false reading.
AdBlue System Malfunctions
If the AdBlue warning light is accompanied by other symptoms, it could be a sign of a problem with the AdBlue system itself, including:
- Clogged AdBlue lines: AdBlue lines can get clogged with debris or frozen AdBlue during cold weather.
- Faulty AdBlue pump: The pump that injects AdBlue into the exhaust system might be broken.
- Defective AdBlue injector: The injector that sprays AdBlue into the exhaust might be malfunctioning.
What to Do When the AdBlue Warning Light Comes On
If you see the AdBlue warning light, don’t panic. Here’s a step-by-step guide on how to troubleshoot the issue:
-
Check the AdBlue fluid level: First, check the AdBlue tank level using the dipstick or gauge on your vehicle. If it’s low, simply top up the tank with fresh AdBlue.
-
Reset the AdBlue warning light: After topping up the tank, you’ll need to reset the warning light. This can be done using a diagnostic tool or by following the instructions in your vehicle’s owner’s manual. You can also consult a professional mechanic for assistance with resetting the light.
-
Inspect the AdBlue system: If the warning light remains on even after topping up the tank and resetting it, there may be a problem with the AdBlue system. Look for signs of leaks, damaged lines, or other visible issues.
-
Consult a mechanic: If you’re unsure about the cause of the AdBlue warning light, it’s best to take your Peugeot Partner to a qualified mechanic. They can diagnose the problem accurately and provide the necessary repairs.
How to Prevent AdBlue Warning Lights
You can prevent future AdBlue warning lights by:
- Regularly checking and topping up the AdBlue tank: Make sure to check the AdBlue level frequently and top up the tank when it’s low.
- Using high-quality AdBlue: Only use AdBlue from a reputable manufacturer, as low-quality AdBlue can damage the system.
- Maintaining the AdBlue system: Regularly inspect the AdBlue system for leaks, damaged lines, or other issues.
