The 2011 VW Sharan, like many modern diesel vehicles, utilizes AdBlue, a urea-based solution, to reduce harmful emissions. However, occasional AdBlue-related issues can arise, prompting the need for a reset. This guide will provide you with a comprehensive understanding of AdBlue reset procedures and troubleshoot common problems.
What is AdBlue and Why Does It Need Resetting?
AdBlue is an essential component in reducing nitrogen oxides (NOx) emissions in diesel vehicles. It works by injecting a urea solution into the exhaust stream, converting harmful NOx into harmless nitrogen and water.
The AdBlue system requires periodic resets, primarily due to:
- Low AdBlue Level: The system monitors the AdBlue level and triggers a warning light when it falls below a certain threshold.
- System Malfunction: Occasional sensor or software errors can lead to system malfunctions, requiring a reset.
Resetting the AdBlue System: Step-by-Step Guide
To reset the AdBlue system in your 2011 VW Sharan, follow these steps:
- Check the AdBlue Level: Begin by ensuring you have enough AdBlue in the tank. If the level is low, refill it before proceeding.
- Consult Your Owner’s Manual: Refer to your vehicle’s owner’s manual for detailed instructions specific to your 2011 VW Sharan model.
- Use a Diagnostic Tool: Most modern vehicles require a diagnostic tool to reset the AdBlue system. This tool allows you to access and interact with the vehicle’s computer systems.
- Follow the On-Screen Instructions: Once connected, follow the on-screen prompts and instructions to reset the AdBlue system.
Important Note: It’s crucial to note that attempting to reset the AdBlue system without proper knowledge and tools could lead to complications. It’s strongly recommended to seek assistance from a qualified mechanic or authorized VW service center.

Here are some common AdBlue issues and troubleshooting tips:
