The evaporator is one of the unsung hero components of the cooling system on the Audi A4. This unsung hero is responsible for converting liquid refrigerant into gas, which more significantly absorbs heat from the cabin air. Located strategically inside the climate control system, this evaporator ensures efficient heat transfer to keep the inside of the A4 comfortable and refreshing during even the hottest days.
This evaporator is designed to Audi's exacting standards and blends in seamlessly with your remaining A/C components to deliver both reliability and long service life. For an Audi enthusiast, the installation of a high-quality evaporator is an essential step toward preserving comfort and functionality in your A4.
The Audi A4 A/C evaporator is an essential component at the core of the vehicle's cooling system. This component performs the fundamental activity of converting refrigerant from liquid form to gaseous form, which facilitates absorption of heat from the cabin air. Due to its position within the climate control system, it allows for proper heat transfer , the A4's air conditioning cools and freshens the interior for the occupants.
Manufactured to Audi standards, the evaporator is built to become a cohesive part of the rest of the A/C equipment and to offer durability in addition to functionality.
This evaporator covers the B8 chassis Audi platform:
Notably, this evaporator covers the famous B8 chassis Audi S5 V8 (2008-2012). See our separate Audi S5 V8 Engine listing for the related 4.2 FSI V8 engine (354 HP, naturally aspirated). The B8 chassis shared between A4/S4/A5/S5 means the same evaporator works across all these applications.
The evaporator is the heat absorption component of the A/C system:
The confirmed primary fitment is the B8 chassis, not the B5. Buyers should verify their specific Audi model and year against this fitment list. If you have a B5 chassis A4 (1996-2001), B6 (2001-2005), or B7 (2005-2008), call (240) 301-0095 for our chassis-specific evaporator availability.
The same evaporator works across various B8 chassis engine options:
| Vehicle | Compatibility |
|---|---|
| Audi A4 (B8 chassis) | 2009-2016 with factory A/C , the primary application |
| Audi S4 (B8 chassis) | 2009-2016 with 3.0 TFSI V6 supercharged engine |
| Audi A5 (B8 chassis) | 2008-2017 (2-door coupe variant) |
| Audi S5 (B8 chassis) | 2008-2017 (including B8 S5 V8 2008-2012 and later 3.0 TFSI V6 supercharged) |
| Audi A4 Allroad | B8 chassis based, generally compatible |
| NOT Compatible | Audi A4 B5 (1996-2001), B6 (2001-2005), B7 (2005-2008), B9 (2016+) , different chassis use different evaporators |
