Audi's turbocharged engines and quattro all-wheel-drive hardware hold up well, which makes a tested unit out of a low-mileage donor a sound alternative to dealer pricing. Audi also shares platforms with Volkswagen and Porsche, which widens what we can source and cross-verify. Every unit we list is cleaned, inspected, and function-tested before it ships.
Send us the year, model, and VIN and our USA-based team confirms chassis code, engine variant, and quattro configuration before anything ships. A4 alone has run through several chassis generations (B6 through B9) with different engines and drivetrain layouts, so model name isn't specific enough to order against.
Chassis generations, quattro matching, and shared VW Group platforms. Need help? Call 1-800-606-1107.
No, generally not. Audi's chassis codes (B6 through B9 on the A4, for example) mark real engineering changes in engine, transmission, and body hardware, even when the model name stays the same. We match by chassis code and VIN.
Yes — quattro models run a different transmission, driveshaft, and rear differential than front-wheel-drive versions of the same car. We confirm drivetrain configuration against your VIN before shipping.
Sometimes — Audi shares the MQB and MLB platforms with Volkswagen and, on some models, Porsche. Certain engines and drivetrain components cross over. We verify the specific part rather than assuming either way.
On a limited basis, as availability allows. S and RS models run different engines, brakes, and suspension hardware from the standard trim, and they move quickly. Call for current stock.
Multitronic is Audi's CVT, used on certain front-wheel-drive models; S tronic is the dual-clutch automatic used more widely, including on quattro models. They're not interchangeable — we confirm the exact type off your VIN.
If we VIN-matched it and it's wrong, we cover the return and replacement. Every eligible order also carries the 90-day warranty.
