Product Details

Arnott AS-3031 is engineered as a direct replacement air suspension strut for the rear left side of the Audi A8 Quattro. It is designed for vehicles equipped with normal suspension and PR Code 1BK, and it replaces the OE strut while providing a custom-tuned response for everyday driving. This part cross-references Audi OE numbers 4E0616001D and 4E0616001E for the same application.

The Arnott NEW product line focuses on replacement air suspension components built with upgraded materials and precise fitment. For the Audi A8 rear air strut application, that means a new assembly with a protected air sleeve, durable upper and lower mounting points, and a hydraulic internal damper matched to the vehicle’s rear suspension layout.

Common Problems This Part Can Address

• Rear suspension sag on the driver side
• Air leaks from a worn air sleeve or fitting
• Excessive bounce or reduced damping control
• Ride-height inconsistency at the rear of the vehicle
• Noise or wear from aging OE air strut components
