• Core height: 22.63 in.
• Core length: 15.44 in.
• Core thickness: 0.56 in.
• Fin height: 5 mm
• Designed for R-134a refrigerant systems
• OE reference numbers include Audi 5Q0 816 411 BF and Volkswagen 5Q0 816 411 BF

Detailed Description

This TYC A/C condenser is a direct-fit replacement for vehicles that use the factory parallel flow condenser layout with an integrated receiver/drier. The condenser core dimensions and configuration support proper refrigerant cooling performance in the HVAC system, making it a practical replacement for a leaking, damaged, or restricted condenser. TYC 4891 is listed for 2015-2020 Audi A3, 2015-2020 Audi A3 Quattro, 2015-2020 Audi S3, 2020 Audi Q3, 2015-2019 Audi A3, 2019 Audi Q3, 2015-2019 Volkswagen Golf R, 2016-2018 Audi A3 Sportback e-tron, 2016-2018 Audi TT Quattro, and 2016-2018 Audi TTS Quattro.

This part cross-references OSC 4891 for the same application.

What It Helps Fix

• A/C refrigerant leaks from a damaged condenser core
• Reduced cooling performance from internal blockage or restriction
• Heat transfer loss that affects cabin air temperature
• Corrosion or impact damage to the condenser assembly
• HVAC service needs on Audi A3, Audi S3, Audi Q3, and Volkswagen Golf R models

Installation Notes and Tips

Verify the vehicle uses R-134a refrigerant and the parallel flow condenser configuration before installation. Confirm core dimensions and OE reference 5Q0 816 411 BF against the original part to ensure proper fitment on Audi A3, Audi S3, Audi Q3, and Volkswagen Golf R applications. System evacuation, leak checking, and correct refrigerant recharge are required after condenser replacement.

Quality Assurance

TYC manufactures replacement HVAC components to OE-style specifications for fit and function. Part number 4891 is built to match the listed application requirements and condenser configuration for the covered Audi and Volkswagen vehicles.
