AA Ignition A/C Compressor Control Solenoid Valve – Replaces 1K0820803E for Audi/Volkswagen, Plug-and-Play, 2yr Warranty

AA Ignition A/C Compressor Control Solenoid Valve is a direct-fit replacement that restores variable compressor control for compatible Audi and Volkswagen models, replacing OEM part 1K0820803E.

If your vehicle's climate system blows weak, inconsistent, or no cold air, a faulty compressor control valve may be the cause. This replacement solenoid valve regulates the variable displacement on Sanden PXE14/16 compressors, restoring proper A/C output without cutting or splicing—it's plug-and-play for matched models. Built to meet original performance specs and backed by a 2-year/24,000-mile warranty, the unit offers an affordable alternative to dealer parts while keeping installation straightforward.

How does this valve restore consistent A/C performance?

The control solenoid modulates compressor displacement so the system can vary cooling output as needed. When the original valve fails, the compressor can stick at low or no displacement, producing weak or no cooling. Replacing it returns proper modulation and helps the system reach target cabin temperatures faster.

• Direct-fit replacement for Sanden PXE14/16 compressor assemblies.
• Restores variable displacement control and stable refrigerant flow.
• Plug-and-play electrical and mechanical connections—no modification required.
