Aston Martin DBX 707 Steering Column Shaft A0934600600

part number A0934600600 identifies the Upper Steering Column Assembly for the Aston Martin DBX and DBX707.

Because the DBX utilizes a Mercedes-Benz electrical and interior architecture, many structural steering components carry Mercedes-Benz part numbers (indicated by the “A” prefix). However, this specific column is uniquely calibrated for the DBX’s electric power steering and column-mounted shift paddles.

1. Component Overview

Part Number (Cross-Ref): MY83-SE3C529-BA (Aston Martin internal) / A0934600600 (Mercedes-sourced OEM).
Type: Electrically adjustable steering column (Tilt & Telescopic).
Compatibility: * Aston Martin DBX (V8 & Straight-Six): 2020–2026.
- Aston Martin DBX707: 2022–2026.
Function: Houses the electric motors for driver position memory and the steering angle sensor. It provides the mounting interface for the steering wheel and the DBX’s specialized magnesium shift paddles.

2. Technical Features

Active Safety: The column includes a “collapsible” safety feature designed to absorb energy during a frontal impact, preventing the steering wheel from being pushed into the cabin.
NVH Management: The shaft is engineered with high-density dampers to minimize engine and road vibration (Noise, Vibration, and Harshness) from reaching the driver’s hands.
Locking Mechanism: Features an integrated electronic steering lock module that pairs with the vehicle’s keyless entry system.

3. Pricing & Market Value (2026 Estimates)

Replacing a steering column is a technical and costly repair, often involving significant labor to remove the dashboard “scuttle” area.

Condition	Estimated Price	Notes
New OEM (Dealer)	$2,800 – $3,400	Includes electric adjustment motors.
Used (Grade A)	$950 – $1,300	Common from low-mileage donor vehicles.
Lower Shaft only	$450 – $600	If only the universal joint/shaft (MY83-3F800-BF) is needed.

4. Installation & Programming

The “Zero Point” Calibration: After installing a new column or shaft assembly, the steering angle sensor must be recalibrated to the “Zero Point” using the Aston Martin Diagnostic System (AMDS). If this isn’t done, the ESP (Electronic Stability Program) and active torque vectoring will likely remain disabled.
Hardware Matching: Ensure you check the Lower Steering Column Shaft (MY83-3F800-BF) as well. If the car was in a front-end collision, the lower shaft is designed to deform before the A09346
