The shark fin antenna on the Audi RS3 is the single point of contact between four important infotainment services and the outside world. AM/FM radio reception, GPS navigation, Audi Connect cellular data and SiriusXM satellite radio all route through this one assembly. When the antenna fails, multiple services drop out at once. Even worse, the most common failure mode is roof water leak from a degraded gasket, which not only kills antenna reception but also causes water damage to the headliner, the dome light wiring, and eventually the body computer wiring under the headliner.
A verified used Audi RS3 antenna restores full infotainment reception and stops roof leaks at a fraction of new dealer pricing. We inspect every assembly: housing condition, gasket integrity, cable connector cleanliness, mounting tab integrity, and paint condition where body-color. We can color-match to your VIN paint code if needed.

The Audi RS3 antenna is an integrated shark-fin assembly mounted at the rear roof position. The plastic housing has an aerodynamic shark-fin profile designed to minimize air noise at highway speed. Inside the housing are multiple antenna elements for different radio services: a planar AM/FM antenna element, a GPS patch antenna (positioned to see the sky), a cellular antenna for the LTE/4G band used by Audi Connect, and a SiriusXM satellite radio antenna.
The base of the antenna has a single threaded stud that passes through the roof panel and is secured with a nut on the underside (accessed by partially dropping the headliner). A gasket between the antenna base and the roof panel seals against water intrusion. Multiple coaxial cables exit the base of the antenna and drop into the headliner area, routing to the radio head unit, the MMI navigation computer, the telematics module and the satellite radio tuner.
The RS3 is known for its distinctive 5-cylinder engine sound, a warbling note produced by the 1-2-4-5-3 firing order that is unique to inline-5 engines. This sound is part of the RS3's appeal and identity in the Audi Sport lineup. The 2.5L TFSI 5-cylinder is the same engine family that powered the iconic Audi Sport Quattro of the 1980s.

The Audi RS3 Antenna I bought from Vaz Auto Solutions is fantastic! The reception has drastically improved, and it was surprisingly simple to install. It's sleek and complements the look of my vehicle perfectly. Definitely recommend it for anyone needing a reliable upgrade. Five stars for Vaz Auto Solutions!
I ended up purchasing the Audi RS3 Antenna from Vaz Auto Solutions. It's decent and does the job, but it's not a night-and-day difference in terms of reception for me. It looks good on the car, though, and feels sturdy enough. If you're in need of a replacement, this one will get the job done.
Note: a fresh gasket is strongly recommended at install (cheap, prevents roof leaks). Verify your vehicle is the correct RS3 generation. Contact (240) 301-0095 within 15 days of delivery.
