AdBlue is a crucial component of modern diesel vehicles, designed to reduce harmful nitrogen oxides emissions. However, if you’re facing issues with your AdBlue system, you might need to reset the start count. This process involves resetting the counter that tracks the number of engine starts since the last AdBlue refill.
This guide will help you understand the importance of AdBlue start count reset, when you might need it, and how to perform it.
Why is AdBlue Start Count Reset Important?
The AdBlue start count is a critical parameter that the vehicle’s computer uses to monitor the AdBlue consumption rate. If the vehicle starts a certain number of times without enough AdBlue, the system will trigger a warning light and potentially restrict engine performance.
Here are some reasons why resetting the AdBlue start count might be necessary:
- Incorrect AdBlue Level Measurement: If your vehicle’s AdBlue sensor is malfunctioning or the AdBlue level is not measured accurately, the start count might be incorrectly incremented.
- After Refilling AdBlue: When you refill the AdBlue tank, it’s important to reset the start count to ensure the system is aware of the new AdBlue level.
- After AdBlue System Repair: If you have recently repaired the AdBlue system, it’s essential to reset the start count to ensure the system is functioning correctly.
How to Reset AdBlue Start Count: A Step-by-Step Guide
The process of resetting the AdBlue start count varies depending on the make and model of your vehicle. However, the general steps involved are:
- Locate the AdBlue Tank: The AdBlue tank is usually located under the hood, near the diesel fuel tank. It is often marked with a blue cap.
- Turn Off the Ignition: Make sure the ignition is turned off and the vehicle is parked in a safe location.
- Refill the AdBlue Tank: If your AdBlue tank is empty or low, refill it with the correct type of AdBlue.
- Open the Hood: Open the hood of your vehicle to access the AdBlue tank and its related components.
- Locate the Reset Button: The AdBlue start count reset button is usually located near the AdBlue tank or within the engine bay. It might be a small button or lever. Consult your vehicle’s owner’s manual or an online resource specific to your vehicle model for the exact location.
- Press and Hold the Button: Locate the reset button and press and hold it for a few seconds. The exact time you need to hold the button will vary depending on the vehicle.
- Release the Button: Once the reset is complete, the warning light on the dashboard should go off, or you might hear a beep. Release the reset button.
Important Note: For certain vehicles, resetting the AdBlue start count might require using a specialized diagnostic tool or connecting to the vehicle’s onboard computer.
