Symptoms of Fault

Reduced lid support, downward movement while partially raised, or creaking and knocking during operation warrant inspection. These symptoms do not establish that the damper alone is responsible; check the mechanism and electrical connections before replacement.

Why Replacement Matters

Renewing a confirmed faulty unit helps restore the intended rear lid operation. Inspect the opposite damper and mounting points at the same time, rather than assuming that replacing one component will resolve every operating fault.

FAQs

Must both units be renewed together?
Two are fitted per vehicle. Assess both units and follow the applicable repair procedure when deciding whether one or both need replacement.

Are mounting clips or brackets included?
The supplied information does not specify additional hardware. Confirm the required fittings before installation.

Is adjustment needed after installation?
Follow the vehicle-specific repair procedure for installation and any required setup.

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 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.
