Volvo FH/FM AdBlue Level Sensor Pick Up Unit 21232204 22203920 Front Euro 6 Used

Description:
Genuine Volvo AdBlue / DEF tank level sensor and pick up unit, OEM part number 21232204 with cross references 22203920, 7421232204 and 7422203920. This assembly combines the AdBlue (urea) level and temperature sensor with the suction tube and return lines for the SCR system on Euro 6 Volvo FH and FM trucks. It fits directly into the AdBlue tank and provides accurate level information to the engine ECU to control NOx emissions.

The unit in this listing is a used original component removed from a working Volvo Euro 6 truck and tested on the vehicle prior to dismantling. The sensor correctly reported DEF level and did not generate dashboard warnings or diagnostic trouble codes. The stainless steel tubes are straight with no dents, the plastic head and electrical connectors are in good condition, and the suction filter screen is present. Only light dirt and minor surface corrosion are visible from normal service.

Typical applications confirmed from online catalogues and listings include Volvo FH4, FM4 and FMX4 series Euro 6 trucks from around 2013-onwards, and related Renault heavy trucks such as Range T that share the same SCR/AdBlue system when using OE numbers 21232204 or 22203920. Always compare your existing part number, connector type and overall length with the photos before ordering.

The part will be supplied as shown in the photos, without additional seals, bolts or hoses. It is strongly recommended to use new sealing gasket or O-ring when installing into the AdBlue tank and to follow Volvo workshop procedures. No coding is usually required when replacing the level sensor on these models, but clearing of stored fault codes and basic checks with a diagnostic tool are advisable after installation.

This is an ideal cost-effective replacement for a faulty or corroded AdBlue tank sensor causing issues such as incorrect DEF level display, AdBlue system failure messages or derate warnings on Volvo FH/FM Euro 6 trucks.
