Nissens 89418 A/C Compressor

Nissens 89418 A/C Compressor Overview

The Nissens 89418 A/C compressor is a direct-fit HVAC replacement for select Audi and Volkswagen applications that use R134A refrigerant. Built around a 7SEU17C compressor design, it is supplied with pre-filled PAG 46 oil and is part of Nissens’ FIRST FIT program for faster installation on the correct application.

For Audi A6 Quattro, A8 Quattro, S4, S5, S6, S8, RS4, RS5, Q7, R8, Allroad Quattro, and Volkswagen Touareg applications, this compressor is specified for vehicles that require an OE-style replacement with the correct refrigerant and oil type. Part number 89418 is also cross-referenced to UAC CO11021C for the same application.

Detailed Product Description

Nissens 89418 is an A/C compressor engineered for vehicles that rely on R134A refrigerant and PAG 46 oil. The FIRST FIT format helps streamline replacement work by matching the application with pre-filled oil and the required sealing components when needed. This makes it a practical choice for restoring air conditioning performance on Audi and Volkswagen platforms where the compressor must match the original system specification.

Compatible With 2004-2005 Audi Allroad Quattro, 2004-2009 Audi S4, 2005-2007 Audi A6 Quattro, 2005-2009 Audi S4, 2007-2011 Audi S6, 2007-2013 Audi A8 Quattro, 2007-2014 Audi S8, 2007-2015 Audi Q7, 2008-2012 Audi R8, 2008-2012 Audi A8 Quattro, 2008-2012 Audi S5, 2008-2012 Audi A6 Quattro, 2008-2015 Audi R8, 2008-2015 Audi RS5, 2008-2009 Volkswagen Touareg, and 2013-2015 Audi RS5 applications listed in the fitment data.

Common Problems This Compressor Can Address

• No cold air from the vents due to compressor failure
• Weak or inconsistent A/C output on R134A systems
• Noisy compressor operation from worn internal components
• Loss of system pressure caused by compressor wear or seizure
• Air conditioning performance issues after an OE compressor failure

Installation Notes and Tips

Verify the vehicle’s compressor type, refrigerant specification, and VIN breakpoints before installation, especially on 2007-2008 Audi A6 Quattro, A8 Quattro, RS4, S5, S6, and Q7 applications with chassis-specific notes. Confirm the system uses PAG 46 oil and R134A refrigerant before charging. Flush the system as needed, replace the receiver/drier or accumulator when required by the repair procedure, and evacuate the system before final recharge.

Use the exact fitment data for the vehicle, including chassis/VIN notes where listed, to ensure the compressor matches the original HVAC configuration. Part number 89418 is intended for direct replacement on the specified applications and should be installed according to the vehicle service manual.

Quality Assurance

Nissens develops and manufactures thermal management components to high quality standards for the aftermarket. The 89418 A/C compressor reflects that focus with application-specific fitment, correct oil pre-fill, and OE-style system compatibility for the listed Audi and Volkswagen vehicles.
