Recently I took my '13 S6 in for a few issues at 152,008 miles. It had a small oil leak, small antifreeze leak, a buzz under the hood and transmission didn't like going into first gear. Well, oil leak is suspected to be bottom of a turbo running across the top and down the front. Last oil analysis showed increased copper, guess I know why now if turbo is getting shorted. Antifreeze is the heater/antifreeze distribution manifold. Buzz is the alternator. Last and definitely not least, likely needs a new transmission. I should also mention the camera for night vision is shattered ($2,900) and the infotainment screen won't retract.

I so loved that car especially with it's upgrades, but now Carvana has it and I have $3,800 towards and new Car. Thinking 2020ish S5 Keep an eye on Carvana to see if a '13 S6 shows up with 152k miles. LOL

For now, got my wife's beater. A 2009 A4 with 124k miles. Audi has rebuilt the engine twice so far.

I just wanted to share my heartache.
