Manufactured by Stabilus, a global specialist in damper and motion-control technology, this electric tailgate strut integrates an internal motor and damping mechanism to precisely manage tailgate movement while supporting the distinctive Coupé tailgate design.

What the Electric Tailgate Damper Does

This powered damper:

• Assists automatic opening and closing of the rear tailgate
  
• Delivers smooth, controlled movement throughout the lift cycle
  
• Supports the tailgate safely when fully open
• Works in harmony with the vehicle’s comfort electronics
• Reduces strain on hinges, latches and body components

It is essential for correct powered tailgate functionality on Cayenne Coupé models.

Why Electric Tailgate Dampers Fail

Common reasons for failure include:

• Internal motor wear from repeated operation
  
• Loss of damping efficiency, causing uneven or jerky movement
  
• Electrical faults within the actuator
  
• Exposure to moisture, dirt and temperature extremes
• General age-related component fatigue

Symptoms may include slow operation, incomplete opening, warning messages or a tailgate that will not stay open.

Why the Tailgate Damper Should Be Replaced

Replacing a worn electric tailgate damper restores:

• Full powered tailgate operation
• Quiet, smooth and controlled opening and closing
• Safe tailgate support in all positions
• Correct interaction with the vehicle’s electronic systems
• Everyday convenience and premium usability

Timely replacement helps prevent further damage to the tailgate mechanism and related components.
