Product Details

CSF 10684 is an A/C condenser for HVAC systems that need a direct-fit replacement with parallel-flow construction and block-fitting ports. The condenser dimensions and connection style are matched for Audi platforms across the 2009-2014 model years, including Audi A4, Audi A4 Quattro, Audi Q5, Audi S4, Audi A5, and Audi S5. CSF reports more than 30 million units sold and manufactures in ISO/TSO certified factories, supporting consistent production standards for this part number 10684.

This part cross-references CSF 3868 for the same application.

Common Problems This Part Can Address

• Weak cabin cooling from a restricted or leaking condenser
• Visible refrigerant oil residue at the condenser core or fittings
• Damage from road debris, corrosion, or front-end impact
• Reduced A/C performance caused by poor heat rejection
• Fitment issues when replacing an original block-fitting condenser

Installation Notes and Tips

Verify the vehicle’s A/C line connection style before installation, since this condenser uses block fittings at both the inlet and outlet. Confirm the application by year, model, and engine configuration where applicable, especially on 2013-2014 Audi Q5 non-hybrid vehicles. Inspect the rest of the A/C system for contamination, leaks, or damaged seals before charging the system.
