In this article, we’ll delve into the reasons behind this warning, the symptoms you might encounter, and the solutions to get your car back on track.
What is AdBlue?
AdBlue is a urea-based solution that is used in diesel vehicles to reduce harmful nitrogen oxide emissions. It works by injecting a precise amount of AdBlue into the exhaust system, where it reacts with NOx gases to convert them into harmless nitrogen and water.

- Low AdBlue Level: This is the most common reason for the AdBlue warning light to appear. It means that your AdBlue tank is running low and needs to be refilled.
- AdBlue System Malfunction: The AdBlue system can sometimes experience malfunctions, such as a blocked injector, a faulty sensor, or a problem with the AdBlue pump.
- AdBlue Quality Issue: The AdBlue solution you’re using might not be of the correct quality or might be contaminated.
- AdBlue Tank Issue: The AdBlue tank itself could be damaged, leaking, or have a faulty level sensor.
