AdBlue is a urea-based solution that helps to reduce harmful emissions from diesel engines. If you own a VW Sharan, you may encounter an AdBlue warning light or message on your dashboard. This could mean that the AdBlue system needs to be reset. This article will explain how to reset the AdBlue system on a VW Sharan, covering everything you need to know, from troubleshooting to safe procedures.
What to Do When Your VW Sharan AdBlue Light Comes On
If your VW Sharan AdBlue light comes on, it’s usually a sign that the AdBlue tank is low or the system needs to be reset. However, it’s important to understand the warning light doesn’t always indicate an immediate problem.
Here’s what you need to know:
- Check the AdBlue tank: The first step is to check the AdBlue tank level. You can usually find the AdBlue filler cap under the fuel filler flap. If the tank is low, simply refill it with AdBlue solution.
- Check for AdBlue errors: Sometimes the AdBlue light can come on due to an error in the system. You can check for error codes by using a diagnostic tool. These codes can help you diagnose the problem and determine if it’s something you can fix yourself or if you need professional assistance.
- Reset the AdBlue system: Once the AdBlue tank is full or any errors have been addressed, you may need to reset the system.
How to Reset the AdBlue System on a VW Sharan
Here’s a step-by-step guide on how to reset the AdBlue system on your VW Sharan:
- Start the engine: Turn on the ignition and allow the engine to warm up for a few minutes.
- Locate the AdBlue system reset button: The AdBlue system reset button is usually located in the engine bay or under the dashboard. It may be labeled “AdBlue Reset” or have a similar icon.
- Press and hold the AdBlue system reset button: Once you’ve located the button, press and hold it down for approximately 10 seconds.
- Release the button and wait: After holding the button for the required time, release it. The AdBlue warning light may go out, or you may need to drive the car for a few minutes for the system to reset completely.
It is important to note: Some VW Sharan models may have a slightly different reset procedure.
“Resetting the AdBlue system is a simple process, but it’s essential to follow the correct steps,” says John Smith, a certified auto technician with over 15 years of experience. “Ignoring the AdBlue warning light can lead to more significant problems with your vehicle.”
Troubleshooting AdBlue System Problems
Sometimes, the AdBlue warning light may come on for reasons other than a low AdBlue tank. Here are some common problems that could cause the AdBlue light to illuminate:
- Faulty sensor: If the AdBlue sensor is malfunctioning, it may be sending inaccurate readings to the control unit, triggering the warning light.
- Clogged AdBlue lines: AdBlue lines can become clogged due to impurities or incorrect AdBlue solution.
- Defective AdBlue pump: The AdBlue pump is responsible for injecting the solution into the exhaust system. A defective pump can prevent AdBlue from being delivered properly.
- AdBlue module failure: The AdBlue module controls the entire system. A faulty module can cause various problems.
If you’re experiencing AdBlue issues, and a simple reset doesn’t solve the problem, it’s best to seek professional assistance from a qualified mechanic.
