AdBlue is a crucial part of your VW Touareg’s emissions system, and when its warning lights come on, it’s important to address the issue promptly. This guide will walk you through the process of resetting the AdBlue warning on your VW Touareg.
Understanding the AdBlue System
AdBlue is a urea-based solution that is injected into your car’s exhaust system to reduce harmful nitrogen oxides (NOx) emissions. The system monitors the AdBlue level and triggers a warning light when it’s running low.
Why Does the AdBlue Warning Light Come On?
Several factors can cause the AdBlue warning light to appear on your VW Touareg:
- Low AdBlue level: This is the most common reason. The system will trigger the warning when the AdBlue tank is low, indicating a need for refilling.
- AdBlue system fault: There might be a problem with the AdBlue pump, injectors, sensors, or other components of the system.
- AdBlue quality issues: Using incorrect AdBlue or a contaminated solution can also cause issues.
- Software malfunction: Rarely, the AdBlue system software might need a reset or update.
How to Reset the AdBlue Warning Light
Important: It’s crucial to refill the AdBlue tank first, then follow these steps to reset the warning light:
1. Start the engine and let it idle.
2. Press and hold the “OK” button on the steering wheel.
3. Navigate to the “Settings” menu.
4. Select “Vehicle” or “Car” (depending on your model year).
5. Choose “AdBlue.”
6. Look for the option to “Reset AdBlue Warning” or similar.
7. Follow the onscreen instructions to reset the warning.
Common Mistakes to Avoid
“I’m Just Going to Ignore It” – Don’t do this. Driving with a low AdBlue level can eventually lead to reduced engine performance or even disable your vehicle.
“I’ll Just Top It Off a Little” – The AdBlue system needs a minimum level to function properly. It’s essential to completely refill the tank whenever you see the warning light.
“I’ll Use Regular Diesel Fluid” – Do not use regular diesel fuel or any other fluid instead of AdBlue. It’s critical to use only genuine AdBlue as it is specially formulated to work with the system.
