Are you driving a Peugeot and suddenly see an AdBlue warning light on your dashboard? This can be a stressful situation, but don’t panic. This guide will walk you through the common causes of an AdBlue warning light in Peugeot vehicles, what you can do to solve the issue, and how to reset the warning.
AdBlue is a crucial fluid that helps reduce harmful nitrogen oxide emissions from your car’s diesel engine. The warning light indicates a problem with your AdBlue system, which could be low AdBlue levels, a faulty sensor, or a blockage in the system.
Why Your Peugeot AdBlue Warning Light Is On
Here are the most common reasons why your Peugeot AdBlue warning light might be illuminated:
1. Low AdBlue Level: The most common cause is simply that your AdBlue tank is running low. AdBlue is a consumable fluid that needs to be refilled regularly. Your car’s computer will usually provide a warning message before the tank completely empties.
2. Faulty AdBlue Sensor: The AdBlue sensor measures the fluid level and quality in the tank. If the sensor malfunctions, it might send false readings, triggering the warning light.
3. AdBlue System Blockage: Over time, the AdBlue system can become clogged with debris, preventing the fluid from reaching the exhaust system. This can be caused by using low-quality AdBlue or by dirt and particles accumulating in the system.
4. AdBlue Injector Issues: The AdBlue injector sprays the fluid into the exhaust system. A faulty injector can cause problems with the AdBlue system and trigger the warning light.
5. Software Glitch: While less common, software glitches can also trigger the AdBlue warning light. This is usually resolved by updating the vehicle’s software.
What to Do When You See the AdBlue Warning Light
-
Check the AdBlue Level: The first step is to check the AdBlue level in your vehicle’s tank. If it’s low, simply refill the tank with high-quality AdBlue. You can find AdBlue at most gas stations and auto parts stores.
-
Reset the Warning Light: After refilling the AdBlue tank, you’ll likely need to reset the warning light. This is usually done by following a specific procedure for your Peugeot model. You can find instructions in your vehicle’s owner’s manual or online.
