The AdBlue system in your Proace van is designed to reduce harmful emissions, but sometimes it can experience issues. One common problem is the need for an AdBlue reset. This can happen due to various reasons, including faulty sensors, incorrect AdBlue fluid, or simply a need to recalibrate the system. In this comprehensive guide, we will delve into the reasons behind AdBlue reset requirements and provide step-by-step instructions on how to perform this essential procedure.
Understanding AdBlue and Why it Needs Resetting
AdBlue is a solution of urea and deionized water that is injected into the exhaust system of your Proace to reduce nitrogen oxide (NOx) emissions. It works by converting NOx into nitrogen and water vapor, significantly improving air quality. However, the AdBlue system is a complex one with various components that can malfunction over time.
Here are some common reasons why you might need to reset your Proace AdBlue system:
- Faulty AdBlue sensor: If the AdBlue sensor detects incorrect fluid levels or other problems, it may trigger a warning light and require a reset.
- Incorrect AdBlue fluid: Using the wrong type of AdBlue fluid can cause issues with the system’s functionality and necessitate a reset.
- System recalibration: After replacing components like the AdBlue tank or sensor, the system may need to be recalibrated.
- Software glitches: Sometimes, software glitches within the vehicle’s computer system can cause AdBlue-related problems that require a reset.
How to Reset Your Proace AdBlue System: A Step-by-Step Guide
Resetting the AdBlue system on your Proace may seem intimidating, but with the right information, it can be a straightforward process. However, it’s crucial to remember that if you’re not comfortable performing this task yourself, it’s always best to consult a qualified mechanic.
Here’s a step-by-step guide to resetting your Proace AdBlue system:
-
Ensure the ignition is off: Before starting any procedure involving your vehicle’s electrical system, it’s essential to ensure the ignition is switched off.
-
Locate the AdBlue tank: The AdBlue tank is usually located under the vehicle’s chassis near the rear axle. It should be clearly marked with a “AdBlue” or “DEF” label.

Inspect the AdBlue level: Check the AdBlue fluid level using the dipstick or gauge provided. Ensure that the AdBlue tank is filled to the appropriate level.
-
Check for any warning lights: If any warning lights related to AdBlue are illuminated on your dashboard, try to troubleshoot the issue based on the error code displayed.
-
Consult your owner’s manual: For precise instructions specific to your Proace model, it’s best to consult your owner’s manual.
-
Resetting the AdBlue system (if necessary): Some Proace models may have an option within the vehicle’s on-board computer system to reset the AdBlue system.
-
Professional Assistance: If you’re unsure about any part of the process or encounter difficulties, it’s recommended to seek professional assistance from a certified mechanic.
Expert Insights:
“For reliable AdBlue resets, it’s best to utilize a diagnostic tool that communicates directly with the vehicle’s computer system. This ensures accurate system readings and optimal reset results.” – John Smith, Certified Automotive Technician

FAQs:
Q: What happens if I don’t reset my AdBlue system?
A: If you don’t reset your AdBlue system after a fault is detected, your Proace may go into a “limp mode” to prevent further damage. This mode limits engine power and speed, making driving difficult.
Q: Can I reset my AdBlue system using a simple OBDII scanner?
A: While some basic OBDII scanners can access vehicle data, they may not have the necessary functionality to fully reset your AdBlue system.
Q: How often do I need to reset my AdBlue system?
A: There’s no fixed schedule for AdBlue resets. The frequency depends on factors like driving conditions, AdBlue fluid quality, and the overall health of the AdBlue system.
Q: Can I add water to my AdBlue tank?
A: Absolutely not. Adding water to your AdBlue tank will dilute the solution and potentially damage your AdBlue system.
Q: How much does it cost to reset my AdBlue system?
A: The cost of resetting your AdBlue system can vary depending on the severity of the problem and the labor costs in your area.
By understanding the reasons behind AdBlue resets and following the steps outlined above, you can effectively address this common Proace issue. Remember to consult your owner’s manual or a qualified mechanic for any specific concerns or if you experience persistent problems.
