31406561 Volvo Blind Spot Rear Sensor G2611 (Left / Right Side).

Product Description

The Blind-Spot / Rear Sensor with Volvo part number 31406561 is an OEM radar / object detection sensor used in Volvo’s BLIS / BSM (Blind Spot / Blind Spot Monitoring) and rear collision warning systems. It monitors the area behind and to the side of the vehicle, detecting moving objects and vehicles entering the blind zone. The module sends alerts to the vehicle’s warning system to assist the driver in lane changes or warning of potential collisions from the side or rear.

This part is typically used (OEM) and tested. Before installation, confirm sensor mounting orientation (left / right), connector type, software version (firmware), and compatibility with the vehicle’s BLIS control unit. A diagnostic tool may be required to pair or configure the sensor after installation.

Compatibility / Notes

The part number 31406561 is genuine Volvo for collision / warning sensor systems.
Volvo parts listing confirms “Sensor. CH, Collision, Warning” under that number.
It is listed in Volvo parts catalog under that number, cross-reference also 31406224, 31451062.
In used part listings, 31406561 is shown as a blind spot / rear side sensor for Volvo V40 specifically (left or right).
One used parts site lists a “Volvo V40 Blind spot module 31406561” for 2014 V40, confirming that the same number is referenced in V40 contexts.
Because many listings are for other Volvo models (V60, S60, XC60) using the same sensor number, whether it fits your V40 depends on the system version (trim, BLIS variant). Use the original sensor’s connector, wiring, and module software as cross-check.
