If you are driving a car equipped with AdBlue, you might have encountered an AdBlue warning light on your dashboard. This warning light is a reminder that your AdBlue tank is getting low. While it’s not a dire emergency, ignoring the warning light could lead to bigger problems down the road. That’s why it’s important to address this issue promptly.
This article will explain what the AdBlue warning light means and how to reset it. We will also discuss how to prevent the warning light from coming on in the first place.
What Does the AdBlue Warning Light Mean?
The AdBlue warning light indicates that the AdBlue fluid level in your vehicle’s tank is low. This warning light may come on when there is only about 1,500 miles (2,400 kilometers) of AdBlue remaining.
It is important to note that the AdBlue warning light is not always a sign that your AdBlue tank is empty. In some cases, the warning light may come on even though there is still some AdBlue left in the tank. However, it is always best to add AdBlue as soon as possible after the warning light comes on.
If you ignore the warning light, you may eventually run out of AdBlue. If this happens, your engine will go into a “limp mode” which will prevent you from driving at high speeds.
