The Genuine Mercedes-Benz door lock vacuum actuator (part number 2117200635) is a factory OEM component designed to control the central locking system in select Mercedes-Benz vehicles. This vacuum-operated actuator uses engine vacuum or vacuum pump pressure to mechanically lock and unlock the door latch mechanism when the central locking system is activated.

Key Features:

• Genuine Mercedes-Benz OEM part ensures perfect fit and reliable operation
• Vacuum-operated mechanism provides smooth, quiet door locking action
• Direct replacement for worn or failed door lock actuators
• Restores proper central locking system function
• Includes vacuum actuator unit with mounting hardware connection points

This actuator is commonly found in Mercedes-Benz W210, W211, and related chassis models that utilize vacuum-based central locking systems. When this component fails, symptoms typically include doors that won't lock or unlock with the central locking system, or one door that operates inconsistently. Replacing a faulty vacuum actuator restores full functionality to your vehicle's security system.
