This AdBlue level indicator is an original AGCO component for the exhaust system of the host tractor. It monitors the fluid level in the AdBlue tank, providing a signal to the engine control unit that manages the selective catalytic reduction process. A failing or inaccurate indicator can cause the system to enter a derated operating mode or trigger a warning light, as the control unit cannot verify the correct fluid supply for emissions reduction. The indicator is designed to match the original housing and connector interface, preserving the electrical signal range that the control unit expects for accurate level reporting.
