20812620 — Adblue Level Sensor 20812620 For Volvo Truck Fh12 Fh16 Nh12 Fh Vnl780

This AdBlue level sensor is a crucial component within the Selective Catalytic Reduction (SCR) system, responsible for accurately measuring the amount of AdBlue (Diesel Exhaust Fluid) in the tank. It ensures the vehicle's emissions control system has sufficient DEF to operate correctly and meet regulatory standards. A faulty sensor can lead to incorrect DEF level readings, triggering dashboard warnings or potentially derating the engine's performance.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial indication of a faulty AdBlue level sensor is an inaccurate or fluctuating reading of the Diesel Exhaust Fluid level on the dashboard display. If this issue persists, the vehicle may display a persistent warning light or even reduce engine power to enforce emissions compliance. The ultimate consequence of ignoring a faulty sensor is the inability to operate the vehicle legally due to emissions system faults.

Installation Tip

Ensure the new sensor is properly seated and sealed to prevent any leaks of AdBlue fluid from the tank. Do not operate the vehicle until the AdBlue tank has been refilled and the system has had time to recalibrate.

Service Note

When replacing the AdBlue level sensor, inspect the AdBlue tank for any contamination and check the SCR system's dosing unit for proper operation.
