Purpose and Function of the Component

The Connector Bracket BMW i3 I01 Front Axle Left Box Carrier Support serves as a precise mounting bracket on the front left side of the vehicle. It is responsible for the correct positioning of components that work with the wheel anti-lock system and driving stability control, which is crucial for accurate wheel signal readings and stable controller operation.

In practice, this means:

• maintaining constant geometry of the connection between the sensor and the rotating wheel components,
• reducing vibrations and play that could interfere with the measurement signal,
• preserving the factory mounting position in accordance with BMW design.

Original BMW Origin and Fitment

As a BMW OE part, the bracket has been specifically designed for the i3 I01 platform, taking into account the characteristics of the electric vehicle's front axle. The original mounting geometry allows for seamless integration with factory mounting points, without the need for modifications or hole adjustments.

The component is particularly useful for:

• repairs after mechanical damage to the front suspension,
• replacing the steering knuckle or wheel carrier after a collision,
• restoring full functionality of ABS/ESP systems after errors related to improper sensor mounting.

Condition, Installation, and Service Application

The bracket is offered as a used part, providing a cost-effective solution while maintaining the original manufacturer's specifications. Such structural components, when free from deformation and cracks, retain full functionality over a long service life.

When installing, pay attention to:

• correct alignment with the wheel axis and steering knuckle,
• checking the condition of bolts and mounting points,
• verifying the proper routing of cables or harnesses cooperating with the bracket.

Importance for ABS and ESP Systems

A correctly mounted bracket directly impacts the stability of wheel signal readings and, consequently, the operation of driving safety systems. Improper positioning or makeshift sensor mounting can result in:

• ABS/ESP error messages on the dashboard,
• incorrect system response during emergency braking,
• interference with driving stability control functions.

Therefore, selecting an original bracket is essential for any repair involving the front left suspension of the BMW i3 I01.
