The Genuine 4L0 131 907 D is an OEM-quality DEF (Diesel Exhaust Fluid) Sending Unit, also commonly referred to as an AdBlue® level sender or SCR fluid level sensor. This unit is designed to accurately monitor the fluid level within the vehicle's DEF/AdBlue tank, transmitting real-time data to the engine control module (ECM) to support proper Selective Catalytic Reduction (SCR) system operation and emissions compliance.

Key Features:

• OEM-specification DEF sending unit for precise fluid level measurement
• Direct-fit replacement engineered to exact factory tolerances
• Ensures accurate DEF level readings to prevent emissions system warnings or faults
• Manufactured to meet original equipment standards for reliable long-term performance
• Compatible with Audi/Volkswagen Group diesel emissions systems using AdBlue® technology
