The heart of climate control is the compressor. The Denso a/c compressor offered by USP Motorsports is a durable OEM replacement. It’s a direct fit for your VW / Audi. Each compressor is brand new, with a new clutch assembly and no remanufactured parts. Every compressor we ship includes instructions and the hardware for proper installation. Each carries a manufacturer’s one-year warranty against defects in materials and workmanship. USP does recommend that you use a professional to diagnose repairs, evacuate the air-conditioning system and recharge it.

A/C control valve failure is common in newer VW / Audi models. Until now, it was necessary to replace the a/c compressor — possibly costing more than $800. Now you can save hundreds. USP offers the a/c compressor control valve only, so you can have a mechanic replace just the valve. This is a non-returnable electronics part, so click to make sure you have the correct control valve before buying.

Don’t overlook the cabin filter. You should replace your cabin air filter according to your vehicle’s maintenance schedule. A replacement filter ensures that your HVAC system pumps in air free of dirt, dust and allergens. Our cabin filters from Mann Filter make replacement easy and economical. They are made with activated charcoal, which also captures odors to keep your cabin fresh. We have filters to fit Audis as far back as 1999, some TT models, and VW GTI, Jetta and Beetle.

We also offer cabin filter freshness kits, which include a new filter and a can of air conditioning system deodorizer. The deodorizer will help the filter function better and longer, and will help eliminate odors. It can be sprayed directly onto the filter or into the a/c system air intake.
