Mercedes Sprinter Steering Angle Sensor – Genuine OEM | NCV3 | #9064640318 (2007–2018)

A failed steering angle sensor on a NCV3 Sprinter removes the ESP system's ability to determine where the driver intends to steer relative to where the vehicle is actually going — disabling the stability control program that intervenes in emergency maneuvers and slippery conditions, and triggering ESP, ABS, and traction control warning lights that won't clear until the sensor is replaced and the system recalibrated. This is the Genuine Mercedes-Benz OEM steering angle sensor for NCV3 Sprinters, a direct replacement that restores accurate steering angle input to the stability and braking control systems.

What This Part Does

The steering angle sensor is an optical or magnetic encoder mounted in the steering column that continuously measures the absolute angular position of the steering wheel and the rate at which it is being turned. This data is fed to the ESP (Electronic Stability Program) control module in real time, where it is compared against the vehicle's actual yaw rate and lateral acceleration to determine whether the vehicle is tracking in the direction the driver intends. When the two don't match — as in understeer or oversteer — the ESP module selectively applies individual brakes and reduces engine torque to correct the vehicle's path. The steering angle sensor is also used by the ABS module for brake force distribution calculations and by the traction control system to determine appropriate power delivery in cornering. When the sensor fails, drifts out of calibration, or develops a communication fault, all these systems lose their steering reference and disable.

Common Symptoms of a Failing Steering Angle Sensor

• ESP, ABS, and traction control warning lights illuminated simultaneously
• Steering angle sensor fault codes stored in the ESP or ABS control module
• ESP system that intervenes incorrectly during normal driving — applying brakes when not needed
• ESP that fails to intervene during a genuine oversteer or understeer event
• Warning lights that return after clearing without any other identified fault

When to Replace

Replace when the sensor is confirmed faulty by XENTRY or a compatible scan tool with active steering angle sensor fault codes, after ruling out the steering column, clock spring, and wiring harness. After replacement, the steering angle sensor must be calibrated with XENTRY — drive the van in a straight line and perform the required recalibration procedure before returning to service.

NCV3 Specific — VIN Verification Required

This steering angle sensor is VIN-specific for NCV3 Sprinters (W906). Steering angle sensor configurations vary by build date, market, and ESP system specification. Always verify your VIN before ordering. Contact us and we'll confirm fitment before you buy.

Fitment
