Purpose and Function in the Vehicle

The presented convertible roof latch with motor and actuator has been designed for BMW E88 models equipped with an opening roof. The component operates in the front body area, where it is responsible for proper locking and unlocking of the roof structure and synchronizing its movement with other system components.

By integrating the functions of a latch, drive, and actuator into a single unit, the convertible roof system can operate predictably and repeatably, which is important for both user comfort and vehicle operational safety.

Compatibility and BMW Compliance

The part comes from the BMW line, meaning its construction is adapted to the vehicle's factory mounting points and electrical and mechanical installations. Using an original solution in the Other category allows for consistency with other convertible roof sub-assemblies, without the need for modifications or adaptations.

The presence of the OEM part number and interchangeable numbers (visible in the technical specifications) facilitates verification of compatibility with specific body variants and model years of the BMW E88. This is particularly important when selecting components for roof systems, where construction differences between variants can be significant.

Performance Characteristics and Installation

As a component installed in the front of the vehicle, the convertible roof latch with motor and actuator operates in a critical body area, exposed to temperature changes and mechanical loads. The design has been developed to ensure:

• stable roof locking in the closed position,
• controlled movement during opening and folding,
• cooperation with the factory roof control system,
• proper fit with the front frame structural elements.

The product is in used condition, allowing for an economical repair of the roof system while maintaining the original BMW construction. Before installation, standard verification of the vehicle's electrical and mechanical systems is recommended to ensure proper cooperation of all components.
