Seeing an AdBlue warning light on your Audi dashboard can be alarming. AdBlue, also known as Diesel Exhaust Fluid (DEF), is essential for reducing emissions in your Audi diesel engine. This warning usually means the AdBlue level is low and needs refilling. However, sometimes the warning light might persist even after a refill, requiring a manual reset. This article will guide you on how to reset your Audi AdBlue warning, empowering you to handle this issue with ease.
Understanding the Audi AdBlue System and Warning Light
Before we delve into the reset process, let’s understand why the warning light illuminates. Your Audi’s AdBlue system is designed to reduce harmful nitrogen oxide emissions. When the AdBlue level gets low, the warning light appears, giving you ample time to refill.
Here’s what the different AdBlue warnings mean:
- Yellow AdBlue light: The AdBlue level is low, but you can still drive a certain distance. Refer to your owner’s manual for the estimated mileage.
- Yellow AdBlue light with a distance countdown: The system is in refill mode, and your driving range is limited. Refill the AdBlue tank as soon as possible.
- Amber or red AdBlue warning with a refueling symbol: The AdBlue tank is empty, or the system has malfunctioned. You might experience limited engine performance or be unable to start the car.

Resetting Your Audi AdBlue Warning
In most cases, simply refilling the AdBlue tank will automatically reset the warning light. However, if the warning persists, you might need a manual reset.
Important Note: Always refer to your Audi owner’s manual for model-specific instructions, as procedures may vary.
Here are the general steps to reset your Audi AdBlue warning:
1. Refill the AdBlue Tank:
- Ensure you’re using the correct AdBlue fluid, specifically formulated for Audi vehicles.
- Carefully pour the AdBlue into the dedicated tank, typically located next to the fuel filler cap. Refer to your owner’s manual for the precise location and filling instructions.

2. Drive Your Audi:
- After refilling, drive your Audi for a few miles to allow the system to recognize the refilled AdBlue. In many cases, this is sufficient to reset the warning.
3. Manual Reset (If Necessary):
- Check your Owner’s Manual: Some Audi models might have a manual reset procedure outlined in the owner’s manual. This usually involves navigating through the car’s infotainment system.
- Use a Diagnostic Tool: If a manual reset option isn’t available or doesn’t work, you might need an OBD-II diagnostic scanner. These tools allow you to communicate with your car’s computer and reset the AdBlue warning.
