The AdBlue system in your 2015 Mercedes Sprinter is designed to reduce harmful emissions from your vehicle’s diesel engine. While this system is essential for environmental protection, it can sometimes cause issues that require resetting. If you’re encountering AdBlue-related problems, you may need to perform a reset. This article will guide you through the process of resetting your 2015 Mercedes Sprinter AdBlue system.
What is AdBlue?
AdBlue is a solution of 32.5% high-purity urea and 67.5% demineralized water. When injected into the exhaust system of your diesel engine, AdBlue reacts with NOx (nitrogen oxides) to convert them into harmless nitrogen, water, and carbon dioxide.
Why Reset Your AdBlue System?
There are several reasons why you might need to reset your AdBlue system, including:
- Low AdBlue level: If your AdBlue tank falls below a certain level, your vehicle may enter limp mode to prevent damage to the emissions system.
- AdBlue sensor malfunction: Faulty AdBlue sensors can trigger error messages and disrupt the system’s operation.
- Software glitch: Sometimes, software glitches can interfere with the AdBlue system’s functionality.
- Incorrect AdBlue refill: Using the wrong type of AdBlue or filling the tank above the maximum level can lead to problems.
