Bentley Bentayga steering gear 4N1423053L

Part Number: 4N1423053L

Restore the precision and effortless handling of your vehicle with this Genuine OEM Electromechanical Steering Gear. As a critical safety and performance component, this steering rack is engineered to communicate road feel directly to the driver while providing the power-assisted refinement expected from a Bentley.

Technical Specifications

• System Type: Electromechanical Power Steering (EPS).

• Compatibility: * Bentley Bentayga (2017–Present).

  • Specifically designed for models with Standard Steering or All-Wheel Steering configurations (Please verify suffix L for your specific chassis).

• Construction: High-strength aluminum housing with integrated electric motor and torque sensors.

Key Features

• Variable Assist: Adjusts steering weight based on driving mode (Comfort vs. Sport) and vehicle speed.

• Active Return: Automatically assists the steering wheel back to the center position for a more natural driving feel.

• Vibration Damping: Integrated software filters out unpleasant road oscillations without sacrificing steering feedback.

Common Failure Symptoms

If your steering gear is failing, you may notice:

• Heavy Steering: A sudden loss of power assistance, making the wheel difficult to turn.

• Mechanical Noise: Clunking or grinding sounds when turning the wheel, often indicating internal gear wear.

• Dashboard Warnings: An “EPS Fault” or “Steering Defective” light on the instrument cluster.

• Fluidless Design: Unlike older hydraulic systems, this unit is dry. Any moisture found inside the bellows usually indicates a seal failure that can short out the internal electronics.

Installation & Programming Notice

Critical: This steering gear is a “smart” component. After mechanical installation, it must be programmed and basic settings must be performed (End-stop learning and torque sensor calibration) using Bentley-specific diagnostic software. Failure to code the unit will result in a total lack of power assistance.

Fitment Verification

Because the steering rack varies depending on whether your Bentayga has Rear-Axle Steering or specific driver-assistance packages, we strongly recommend providing your VIN at checkout to ensure part number 4N1423053L is the correct iteration for your build.
