Detailed Description

Arnott A-3892 is an air suspension spring assembly for the rear left side of the Audi C7 platform. It is engineered for vehicles that use rear air suspension and is a direct-fit replacement for the listed Audi A6, A6 Quattro, S6, S7, and RS7 applications. This part cross-references Audi 4G0616001AA and 4G0616001K for the same application.

Construction details matter in air suspension service, and this unit uses a multi-ply ContiTech air sleeve, heavy-duty crimping rings, and anodized metal components to support consistent fit and function. The included airline fitting helps streamline replacement work on the rear left air spring assembly. Arnott recommends replacing air springs in pairs when servicing the suspension system.

Common Problems This Part Can Address

• Rear corner sagging on an Audi A6, A6 Quattro, S6, S7, or RS7
• Air leaks from a worn bellows or cracked air sleeve
• Uneven ride height at the rear left suspension position
• Compressor strain caused by a leaking air spring
• Loss of ride quality from aging air suspension components

Installation Notes and Tips

Verify rear left fitment before installation and confirm the vehicle is equipped with air suspension. Inspect the airline, mounting points, and surrounding suspension components for wear or damage during replacement. Because Arnott recommends pair replacement, service both rear air springs when the opposite side shows similar age or wear.

Quality Assurance

Arnott manufactures this replacement air spring in the USA and uses application-specific materials and hardware for the listed Audi models. The A-3892 is part of Arnott's NEW line of aftermarket suspension components for direct replacement service.
