The Mercedes Sprinter 2016 is a popular van known for its reliability and performance. However, like any vehicle, it can experience issues, and one common problem is with the AdBlue system. AdBlue is a urea solution that is injected into the exhaust system to reduce NOx emissions. When the AdBlue system malfunctions, it can cause problems such as reduced engine power, warning lights, and even a complete engine shutdown. In this article, we’ll discuss how to reset the AdBlue system in your 2016 Mercedes Sprinter.
Understanding AdBlue Reset on a Mercedes Sprinter 2016
The AdBlue reset procedure on a Mercedes Sprinter 2016 involves essentially clearing the fault codes related to the AdBlue system. This process usually involves using a diagnostic tool to access the vehicle’s computer system.
The AdBlue system is an integral part of the Sprinter’s emission control system. When the system detects a fault, it triggers an error code. This fault could be due to various issues such as:
- Low AdBlue Level: The system needs a sufficient level of AdBlue to function correctly. If the level drops below a certain point, the system will trigger an error.
- Defective AdBlue Sensor: The AdBlue sensor measures the concentration of the solution. If the sensor malfunctions, it may provide incorrect readings leading to errors.
- Clogged AdBlue Lines: The AdBlue solution is delivered to the exhaust system through a network of pipes. If these lines become clogged, it can hinder the flow of the solution.
- AdBlue Pump Failure: The AdBlue pump is responsible for injecting the solution into the exhaust system. If the pump fails, it can lead to errors.
Before attempting to reset the AdBlue system, it is crucial to understand the root cause of the fault. Simply resetting the system without addressing the underlying issue will only lead to the problem recurring.
When Should You Reset the AdBlue System?
You should only reset the AdBlue system on your Mercedes Sprinter 2016 after addressing the underlying issue.
Here’s a breakdown of when it’s appropriate to perform a reset:
After Filling the AdBlue Tank: If the warning light is on due to a low AdBlue level, topping up the tank should automatically reset the system.
After Replacing a Defective Component: After replacing a faulty AdBlue sensor, pump, or fixing a clogged line, resetting the system allows it to recognize the new component and function correctly.
After a Diagnostic Check: After addressing a diagnosed fault within the AdBlue system, a reset helps the system recognize the repair and clear any stored error codes.
Important Note: If you’re experiencing ongoing AdBlue system errors, it’s essential to consult a qualified technician to diagnose the problem properly.
