2019 Audi S4 Prestige | Florett Silver | 50k Miles | $32k OBO |

[TeamBlue]

Hey everyone—up for sale is my 2019 Audi S4 Prestige. It’s been my pride and joy, and I’ve built it with care, using top-tier parts and working with KB Motorsports here in SoCal. It’s fully loaded from the factory (Prestige + Sport Diff + Black Optics + Nappa Leather), and I’ve taken it to a tasteful Stage 2+ setup that’s fast, smooth, and daily-drivable.

Right now, the car is tuned for 91 octane, but it has every supporting mod for E85 if you want to unlock more power down the road. I’ve kept all the OEM parts, so if you’re in a state that needs a smog check or want to go back to stock, no problem.

This thing rips when you want it to and cruises like a luxury car the rest of the time. I’m only letting it go because life’s shifting priorities around—and honestly, it deserves to be in the hands of someone who’ll enjoy it as much as I have. Window sticker is attached and I will post some updated pics shortly.

Hey Hey, thank you, I appreciate it. Bittersweet to say the least. To be honest I'm not too sure. I've been ALL over the place from a Camaro ZL1, GT350, C7 Grand Sport Corvette. Back to the American muscle scene maybe? But also looking at the new Golf R, Integra Type S, Civic Type R. I legit have no idea what's next. Mainly looking at more of a "handling" car. That's not to say the S4 doesn't handle well but something purpose built for the twisties. I've got a TON of canyon roads where I live and while going fast in a straight line is extremely fun, im looking for more technical driving.

Beautiful build! How many miles have you had the tune on the car and have you had any mechanical issues since the tune?

Thank you! I've been stage 2+ for probably around 30k miles. I'd say a majority of ownership :)

Full transparency, No mechanical issues but I did end up replacing the injector on cylinder 3 about a month ago after getting code P02D1. I had the shop do a compression test and bore scoped the cylinder confirming no internal damage. I suspect it was due to running E85. I use Chevron 91 when not running E85 and all oil changes are Liqui Moly.
