The AdBlue warning light on your Peugeot 208 can be a bit of a head-scratcher, especially if you’re unfamiliar with the system. This light indicates a problem with your car’s AdBlue system, which is crucial for reducing harmful emissions. Don’t panic! We’ll explain what the warning light means, why it’s important, and how to troubleshoot it.
What is the AdBlue System?
AdBlue, also known as DEF (Diesel Exhaust Fluid), is a solution of urea and deionized water that’s injected into your Peugeot 208’s exhaust system. It helps to break down harmful nitrogen oxides (NOx) emissions into harmless nitrogen and water. The AdBlue system is a vital component in modern diesel vehicles, ensuring they meet stringent emissions standards.
Why Is My AdBlue Warning Light On?
The AdBlue warning light can illuminate for several reasons, most commonly:
- Low AdBlue Level: This is the most frequent cause. The AdBlue tank needs to be refilled when the level drops below a certain point.
- AdBlue Quality Issues: If you’ve used the wrong type of AdBlue or if it’s contaminated, the system might detect a problem and trigger the warning light.
- AdBlue Injector Problems: The AdBlue injector is responsible for precisely injecting the fluid into the exhaust system. If it malfunctions, the light will come on.
- Sensor Malfunction: The AdBlue system relies on various sensors to monitor fluid levels, temperature, and other parameters. A faulty sensor can cause false warnings.
What To Do When the AdBlue Warning Light Comes On
-
Check the AdBlue Level: The first thing to do is check the AdBlue level in your Peugeot 208’s tank. You can usually find the AdBlue filler cap near the diesel tank. If the level is low, simply refill it with the correct type of AdBlue (refer to your owner’s manual).
-
Inspect AdBlue Quality: Make sure you’re using the right type of AdBlue for your vehicle. If you’ve recently refilled it, ensure that the fluid isn’t contaminated.
-
Reset the Warning Light (If Applicable): In some cases, after refilling the AdBlue tank or addressing a minor issue, you might need to reset the warning light. Consult your owner’s manual or a trusted mechanic for the correct procedure.
-
Seek Professional Help: If the AdBlue warning light persists after checking the fluid level, quality, and attempting a reset, it’s crucial to take your Peugeot 208 to a qualified mechanic. A thorough diagnostic scan can help pinpoint the issue and prevent further problems.
