Is your diesel engine vehicle flashing a warning about low AdBlue levels and limited starts remaining? Don’t panic! This is a common issue and often easily fixable. This article will guide you through understanding AdBlue, recognizing the warning signs, and most importantly, how to reset the AdBlue remaining starts counter in your vehicle.
Why AdBlue Matters
Before we dive into the reset process, it’s crucial to understand what AdBlue is and why it’s essential for your vehicle. AdBlue, also known as Diesel Exhaust Fluid (DEF), is a non-toxic solution injected into your diesel engine’s exhaust system. Its primary function is to break down harmful nitrogen oxides (NOx) emissions into harmless nitrogen and water vapor, reducing your vehicle’s environmental impact and meeting emission standards.

Recognizing the Warning Signs
Your vehicle has several ways of letting you know about low AdBlue levels:
- Warning Messages: Most modern vehicles display messages on the dashboard like “AdBlue Level Low,” “AdBlue Refill Required,” or “Starts Remaining Until Engine Start Prevented.”
- Warning Lights: A specific warning light, often resembling a stylized AdBlue container or a general engine warning light, might illuminate on your dashboard.
- Limited Engine Starts: As the AdBlue level gets critically low, your vehicle might limit the number of remaining starts to encourage you to refill the AdBlue tank promptly.

Gearing Up for the Reset
In most cases, simply refilling the AdBlue tank will automatically reset the remaining starts counter. However, if the warning persists even after a refill, you might need to manually reset the system. Here’s what you might need:
- AdBlue Fluid: Ensure you use the correct type of AdBlue fluid specified for your vehicle. Using incorrect fluid can damage the system.
- Diagnostic Scanner: In some cases, you might need a diagnostic scanner to communicate with your vehicle’s onboard computer and reset the AdBlue system.
Resetting the AdBlue Remaining Starts
1. Consult Your Owner’s Manual: Your vehicle’s owner’s manual is the best resource for specific instructions tailored to your make and model. It will outline the correct AdBlue reset procedure for your vehicle.
2. Refill the AdBlue Tank: Ensure the AdBlue tank is filled to the recommended level.
3. Automatic Reset: In many vehicles, the system automatically resets the remaining starts counter after a successful AdBlue refill and a short drive.
4. Manual Reset (If Necessary): If the warning persists, you might need to manually reset the AdBlue system. This usually involves using a diagnostic scanner to access the vehicle’s onboard computer and clear the error codes.

Important Note: While the manual reset process might seem straightforward, it’s generally recommended to consult with a qualified mechanic or dealership for assistance, especially if you’re not comfortable working with diagnostic equipment.
FAQs About AdBlue Systems
Q: Can I drive with low AdBlue levels?
While you can technically drive with low AdBlue levels for a short period, it’s not recommended. Driving with an empty AdBlue tank can trigger an engine malfunction or even prevent your vehicle from starting.
Q: What happens if I accidentally put diesel fuel in the AdBlue tank?
Do not start your engine if you’ve accidentally filled the AdBlue tank with diesel fuel. Contact your dealership or a qualified mechanic immediately, as this requires professional draining and cleaning of the AdBlue system.
Q: How often should I refill the AdBlue tank?
The AdBlue consumption rate varies depending on driving conditions and engine load. However, most vehicles will require an AdBlue refill between service intervals.
