Product Details

Arnott’s air suspension compressor line focuses on replacement components for factory air ride systems, and P-3278 follows that approach with a complete compressor assembly for Audi C7 and 4G chassis vehicles. This part number is built for the 2012-2018 Audi A6, 2012-2018 Audi A6 Quattro, 2012-2018 Audi A7 Quattro, 2014-2018 Audi RS7, 2013-2018 Audi S6, 2013-2018 Audi S7, and 2016-2017 Audi A7. It cross-references Audi 4G0616005C and 4G0616005D for the same application.

Arnott P-3278 is intended to restore proper air supply to the suspension system when the original compressor is worn, noisy, or no longer building pressure correctly. The integrated dryer helps manage moisture in the air system, while the plug-in electrical connectors support faster installation on the vehicle.

Common Issues This Part Can Address

• Compressor runs but does not build sufficient air pressure
• Suspension warning light related to air supply faults
• Slow vehicle height recovery after startup
• Compressor noise from a failing OE unit
• Air suspension performance loss caused by system leaks

Installation Notes and Tips

Before replacing the compressor, inspect the air springs, lines, and fittings for leaks. Arnott notes that compressor failure often starts with a leak elsewhere in the air suspension system, especially in the rubber air springs. Confirm connector style, voltage, and OE part number match before installation on your Audi A6, A7, S6, S7, or RS7.

Quality Assurance

This is a new Arnott replacement component built to standard grade specifications for air suspension service. The compressor assembly includes the dryer and relay listed in the product data, supporting a straightforward OE-style repair on Audi air suspension systems.
