The AdBlue system in your Mercedes Benz Sprinter plays a crucial role in reducing harmful emissions, but what happens when it throws a fault code? You might be wondering how to reset the AdBlue system and get your van back on the road. This guide will delve into the intricacies of AdBlue resets, providing you with comprehensive information and steps to address this issue.
What is AdBlue and Why is it Important?
AdBlue, also known as DEF (Diesel Exhaust Fluid), is a non-toxic solution containing urea and deionized water. It’s injected into the exhaust system of modern diesel vehicles, such as the Mercedes Benz Sprinter, to reduce nitrogen oxides (NOx) emissions. NOx is a major air pollutant, contributing to smog and acid rain.
AdBlue is essential because it allows your Sprinter to meet stringent emission standards. Without a functional AdBlue system, your vehicle will likely experience reduced performance, potentially leading to engine damage and a restricted driving range.
When Do You Need to Reset AdBlue on Your Mercedes Benz Sprinter?
Several situations might require an AdBlue reset:
- Low AdBlue Level: When the AdBlue tank runs low, your Sprinter’s system will trigger a warning message. This message typically prompts you to refill the tank.
- AdBlue System Malfunction: Sometimes, the AdBlue system itself might experience a malfunction, such as a clogged injector or a faulty sensor. This can lead to error codes and require a reset.
- After Refilling AdBlue: After refilling the AdBlue tank, you might need to reset the system to ensure it recognizes the new fluid level.
Can You Reset AdBlue Yourself?
You can certainly reset the AdBlue system on your Mercedes Benz Sprinter yourself, but it requires some technical knowledge and the appropriate tools. We’ll provide you with a step-by-step guide later in this article. However, if you’re uncomfortable performing this procedure, seeking professional assistance is always a wise choice.
