Purpose and function in the suspension system

The offered item belongs to the Steering rods and ends category and operates in the rear part of the suspension on the left side. Its task is to mechanically connect the height sensor to the moving parts of the suspension, so that changes in wheel position are accurately reflected in the signal sent to the vehicle's control units. A properly functioning sensor with a rod contributes to:

• maintaining the correct vehicle ride height relative to the road surface,
• vehicle stability under changing load conditions,
• the operation of comfort and safety systems linked to the suspension.

Compatibility with BMW i4 G26

This height level sensor with rod has been designed specifically for the BMW i4 G26 model, taking into account the rear axle geometry and the vehicle's electronic requirements. Placement on the rear left side eliminates the risk of installation errors and allows for compliance with factory mounting points. As a result, the suspension system maintains predictable reactions, and adaptive control systems can operate within a stable range.

Characteristics as a BMW part

As a BMW brand component, the height level sensor with rod is structurally matched to the vehicle manufacturer's standards. This means maintaining appropriate connection rigidity, correct operating angles, and compatibility with factory wiring harnesses and control units. A used OEM part is a good solution for users who want to:

• maintain original suspension performance parameters,
• avoid modifications to mounts and installation,
• maintain consistency with other chassis components.

Condition and service application

The offered height level sensor with rod is in used condition, which allows for an economical repair of the suspension system while maintaining the original BMW specification. It is particularly useful in situations where:

• mechanical damage to the rod or sensor housing has occurred,
• replacement of a component on one side of the axle is necessary after a collision,
• system errors related to suspension height readings appear.

Using a part from the same design group helps reduce vehicle downtime and facilitates service work without the need to adapt aftermarket replacements.
