Setup, Compatibility & Care
Compatibility: This actuator is specifically designed for Mercedes-Benz Vito W639 (model years 2004-2014) and Mercedes-Benz Viano models. Ensure your vehicle falls within these ranges and is a rear-wheel-drive variant. Verify that the original part numbers match or are listed as cross-references (6397400035, 6397401635, A6397400035, AA6397401635).
Setup: Installation typically involves removing interior trim panels around the tailgate, disconnecting the old actuator, and connecting the new one. Securing the new actuator and reconnecting any linkages are key steps. Due to the complexity and potential for damage, professional installation by a qualified mechanic is often recommended.
Care: As an electromechanical component, the actuator itself requires no regular user maintenance. However, keeping the surrounding tailgate mechanism clean and free of debris can help ensure smooth operation. Regularly test the tailgate lock function to identify any potential issues early.
