Detailed Description

This trunk lock actuator motor is built for BMW trunk latch assemblies that use an automatic trunk mechanism or latch and actuator assembly, depending on the application. The Dorman 940-151 is engineered as a direct OE-style replacement for BMW 330i, BMW 530i, BMW 540i, BMW M340i, BMW M5, BMW 740i, BMW 840i, BMW M8, and related models listed in the fitment data. It is designed to restore proper trunk latch function by replacing a worn or failed actuator motor while retaining the factory wiring connection.

As a trunk lock actuator motor, this part is intended for vehicles with electrical trunk release operation. The housing uses metal and plastic materials, and the connector is a rectangular male style with pin terminals for factory integration. Dorman 940-151 is a practical replacement choice when the original trunk actuator no longer responds correctly or the trunk latch assembly is not operating as expected.

What It Helps Fix

• Trunk will not latch or release properly
• Intermittent or nonresponsive power trunk operation
