OEM Audi AC System Parts

Refine Results

What an Audi AC system does is straightforward: it keeps the cabin cool during a drive. It does so in four steps, equivalent to the four parts that make up the system.

First, a compressor pressurizes the refrigerant, transforming it into a hot gas. Second, a condenser cools the gas, converting it back into a liquid. Third, an expansion valve draws the fluid in, and it becomes a gas once more as it goes, though, this time, at a lower pressure. Fourth, and lastly, an evaporator cools the gas down rapidly, with assistance from a fan. The result: chilled air, which travels through your vehicle's ducts, out its vents, and into its cabin, keeping you and your riders comfortable when the weather's warm.

Unfortunately, car air conditioning seals can weaken sometimes, often just from use and age. An air conditioner's hoses can even degrade and break, not to mention that AC compressors can go bad every so often. Luckily, there are signs to tell you what the problem is. For instance, if the system's not cooling properly, leaking refrigerant is usually to blame, if not low levels of it. For another example, if you're seeing higher-than-normal cabin temperatures, hearing strange noises during operation, or your compressor clutch is stuck, you've probably got compressor problems. Of course, if you've got frost buildup, your AC button is flashing, the HVAC warning light's lit, or you've got issues with discharge pressure, it means you've likely got AC condenser problems.
