The AdBlue system in your 2013 Audi Q7 plays a crucial role in reducing harmful emissions. However, you may encounter situations where the AdBlue system requires a reset. This can be due to various factors, including a faulty sensor, a low AdBlue level, or a software error. This guide will provide you with a comprehensive understanding of the AdBlue system and how to reset it effectively on your 2013 Audi Q7.
Understanding the AdBlue System
AdBlue is a solution of urea and deionized water that’s injected into your vehicle’s exhaust system. When heated, it breaks down into ammonia, which reduces NOx emissions. Your 2013 Audi Q7’s AdBlue system includes a tank, a pump, a sensor, and a control module.
The AdBlue sensor monitors the fluid level in the tank and sends this information to the control module. The control module then determines when to inject AdBlue into the exhaust system. If the AdBlue level drops too low or the system malfunctions, you might receive an error message on your dashboard, limiting your vehicle’s performance.
Common Reasons for an AdBlue Reset
Here are some common reasons why you might need to reset your 2013 Audi Q7’s AdBlue system:
- Low AdBlue Level: When the AdBlue level falls below a certain threshold, your vehicle’s computer might trigger an error message.
- Faulty AdBlue Sensor: A faulty AdBlue sensor can lead to inaccurate readings, causing the system to malfunction.
- Software Error: Sometimes, software errors within the AdBlue control module can necessitate a reset.
- Incorrect AdBlue Type: Using the wrong type of AdBlue solution can damage your vehicle’s system.
- AdBlue Tank Contamination: If the AdBlue tank is contaminated, it can affect the system’s functionality.
