Is the AdBlue indicator in your Audi A6 illuminated? Don’t panic! This article explains everything you need to know about the AdBlue indicator, potential problems, and solutions, so you can drive with peace of mind and avoid unnecessary workshop visits. We will cover the meaning of the AdBlue indicator, give you troubleshooting tips, and show you how to save costs in the long run.
What Does the AdBlue Indicator in the Audi A6 Mean?
The AdBlue indicator in your Audi A6 is part of the emission control system and signals that the AdBlue fill level is low. AdBlue, a urea solution, is injected to reduce nitrogen oxides in the exhaust gas and thus minimize environmental pollution. Do not ignore the indicator, because if the AdBlue fill level is too low, the engine can no longer be started.
AdBlue: Basics and Functionality
AdBlue is a non-toxic, aqueous urea solution used in the SCR catalytic converter (Selective Catalytic Reduction) of your Audi A6. It converts harmful nitrogen oxides into harmless nitrogen and water vapor. The system is essential for compliance with current emission standards. “The correct AdBlue quality is crucial for the optimal function of the SCR system,” emphasizes Dr. Klaus Müller, expert in emission control technology, in his book “Modern Exhaust Aftertreatment”.

AdBlue Indicator Light Is On: Possible Causes and Solutions
If the AdBlue indicator light is on, in most cases it means that the AdBlue tank needs to be refilled. You can purchase AdBlue at gas stations or specialist retailers. Make sure to use the correct AdBlue quality. However, sometimes the indicator may also light up due to system errors. Possible causes include a defective AdBlue sensor, problems with the AdBlue pump, or a clogged AdBlue injector. In such cases, you should visit a specialist workshop.
AdBlue: Save Costs and Avoid Problems
To avoid high repair costs, you should regularly refill the AdBlue tank and check the quality of the AdBlue. “Regular maintenance and the use of high-quality AdBlue can significantly extend the lifespan of the SCR catalytic converter,” says engineer Anna Schmidt, specialist in vehicle diagnostics, in an interview. Also, make sure not to run the AdBlue tank completely empty.
