The 2011 Mercedes-Benz GL350 is equipped with a sophisticated AdBlue system that helps reduce harmful emissions. This system uses a urea solution to neutralize nitrogen oxides (NOx) in the exhaust gases. However, sometimes the AdBlue system may require a reset, especially after performing maintenance or encountering certain error messages. This guide will provide you with a step-by-step walkthrough on how to reset AdBlue on your 2011 GL350.
Understanding the AdBlue System and Resetting
The AdBlue system in your 2011 GL350 is essential for meeting emissions standards. When the AdBlue tank is low or the system encounters problems, the vehicle’s computer system may trigger a warning light or restrict engine performance. Resetting the AdBlue system can be necessary in a few scenarios:
- Low AdBlue Tank: After refilling the AdBlue tank, you may need to reset the system to recognize the new level.
