This is the '07, now wish I could have gotten a MY08 or newer as I could do needle sweep and oil temp in the DIS…
That is the plan, I need to put a bit more $ in prior to it seeing the track but one day itll be there 
I should do an intro since I posted today.
My name is Michael, I recently (Oct '18) bought a 2007 S6. I’ve been surfing the forum for a while to help me with my purchase and help understand things on my car.
VAG Car history: I’ve had a few Audi’s. I’ve had a TT, A5 manual, S5, two A3’s, current sedan and previous gen hatch. Many VAG other vehicles, lots of air cooled stuff when I was a kid in the eighties, probably over 10 type 1’s, one '69 transporter, a 412 wagon, and a '60 Karman Gia.
I recently changed jobs, which caused me to loose my assigned car, which was a chain of 6 Passats, so I wanted another car to supplement my '12 Tundra that mostly sits in the driveway and helps with my motorcycle and track day addiction. At first I wanted another 928. I had a 1980 manual that I loved, but it wasn’t a good choice for a daily driver… plus the cost of upkeep can be prohibitive (not to this crowd, maybe?) Next I thought I would try to find an S5 Manual V8. I loved my T3.0 S6, but it didn’t make the right sound. But, a two door just wasn’t right anymore for several reasons. Then I fell upon the C6 S6 through kind of a strange way. There was a C6 A6 avant for sale near me for a ridiculously low price. I loved the styling, subtle but strong. The 3.2 V6 was a nice engine, but not enthusiastic. So some research revealed the A6 S-line had the 4.2 V8… there ya go! but the rear timing chain with plastic tipped gears was not a strength… Finally, I realized there was a V10 S6 for a few years.
Even though I consider myself an Audi enthusiast, I was not aware of this model. Where I live in Tennessee, I had never seen one. Through my purchase process and by browsing the forum, I really believed they only sold them in in a few areas of the country… it appears to be New England, Detroit, Houston, and West Coast (I know how generalizing I am being).
So I started reading the forum and searching. I really came close to buying a Grey car, and drove a couple of black ones. But when I saw the Sprint Pearl Blue, I was in love.
So I flew to New York, took a bus out to the Hamptons, and drove it the 1000 miles home.
So far I have:
- Replaced a tire
- Turned off the tire monitoring system for now.
To be done:
- Intake off now, carbon clean in process.
- Broke 5 of the injectors pulling for cleaning, bought a new set to go in on reassembly.
- Intake spacers here for install.
- New coils/plugs.
- New breather and drain tube.
- New upper control arms.
- Paint correction, one headlight to buff.
- A tune? APR or JDM?
- Something with the exhaust? Not totally sold on this.
- RS6 Grill maybe.
Otherwise, love the car. Like the combination of practicality, comfort, torquey feel, sound, stealthy looks.

Welcome! That blue is my favorite color.
Welcome, that blue is a very sexy color! So I’d definitely go with the JHM tune and JHM exhaust (when you’re willing). I’ve owned my S6 for a little over a year now and those two items make a HELL of a difference. With the exhaust, you truly bring out the V10 sound that you’re looking for (and it’s a big fuck you to all the Mustang GT and Camaro guys if they’re a nuisance like they are here in Houston). Then the JHM tune… my god. I’ll put the car in sport to discourage any Mercedes AMG sedans or BMWs from doing anything stupid. It’s incredible, and the high rev just sounds flat out MEAN. I’ll have to post some videos post “JHM’d” to show you a little bit what I’m talking about.
please do! 
Hello All!
Bid on a one owner, dealer maintained, one accident, 73k, silver S6 with black leather.
Oddly, this car came to Manheim auto auction a few weeks ago, with a starting bid at 7K. It had a lean bank 1check engine light and ugly after market rims. I bid up to 8, as my friend who knew I was looking for a car saw it and suggested I jump. I was uneducated on the platform completely, but I did see the potential. It sold for 10k and I was bummed.
The car’s new buyer was a wholesale dealer who relisted the car with a starting bid of 5500, and no one bid on it. My buddy knows him well, and said he does not look over the cars mechanically or try anything. I was bummed again to have missed out on a deal, but my buddy said the wholesaler sold it to another wholesaler privately. This new whole saler listed the car at auction for $4900.
My buddy was ready to go with a bid, and he snagged it for me for $5000.00 on 8/23. I had only seen videos and photos of it until today.

I budgeted 3500 bucks for
new hitachi injectors,
spark plugs,
JHM IM spacer
JHM Intake manifold.
I purchased the 3D printed carbon cleaning port adapter to try my hand at a walnut blast carbon clean when I have all the parts prepared.
I test drove the car at the auction today and… holy shit it’s got balls. I have a stage 2, custom tuned mazdaspeed 3 now, and the S6 blows it away , even with this air leak.
The interior is clean, minus a crack in the passenger carbon fiber inlet, and passenger side Bose speaker grill. Otherwise very clean.
The exterior has a lot to be desired. Seems like both bumpers are roughed up underneath. Front led strip cover is cracked. Paint isn’t too bad, needs a good detailing.
I pay my buddy tomorrow, and he plans to clear the vacuum leak/ code and have PA state inspection done for me.
I’m so pumped. I should be driving it mid week this week.
We are all there to help you out on this.
The blast adaptor you can return its just a BMW adapter you can get from anywhere unless you didn’t pay much for it. But to be honest the best cleaning method is chemical. and I have cleaned dozens and dozens of these cars.
The JHM parts are smart. Get a ross tech vag com don’t skimp out that is a must. From there we can all help you though all of this. and anything you might need.
I bought the adapter off the audizine user Ford prefect, is it really not worth the money? Working on getting the Ross-tech off of someone on craigslist.

What a steal! I hope all is well with your S! Looks sharp from the photos. 
Welcome great looking wagon. Looks sharp
The car has 85k on it now. It’s the best car I’ve owned. Had the T fitting by the coolant reservoir break when my wife was driving, and a tie rod is going bad, but otherwise it’s awesome. Enjoy!
The blaster adaptor I wouldn’t even use. A lot of the guys that do the blast method just don’t get the best results. Just two weeks ago I did a carbon clean for someone who did their own 6 months ago with a blast method. It looked like it hadn’t even been done in the past 8 years. Chemical is the way to go.
Ross-tech is always good.
That dam coolant T gets everyone sooner or later.
The whole coolant return line with the t-connector and the weird pipe on top looks like it was crammed in afterwards by some backyard hillbilly mechanic. What were they thinking?
I’m having the front return pipe and hoses changed, as well as a new pump/thermostat assembly. To a tune of about 700e… parts only.
Bills do pile up quickly, so I see why most ppl are tempted to leave stuff broken if it ain’t critical. But then it gets super expensive over time.
Oh, Justincredible: what kind of chemical cleaning do you mean? Can we do a diesel/FSI intake clean without removing the intake, say every 7000mi/10000km and be okay? Or do you mean removing intake manifold and spraying chems into the intake tracts and brushing everything off, etc?
Meida blasting IMO isn’t the best as it just leaves too much you can’t see.
Chemical with the intake off is the by far the best way to go.
You can do the chem spray into the intake track as that works. Not as well as the intake off chemical soak method.
The big down fall with the intake on spray method is that the carbon you clean off will go into the cats. And that will destroy the cats. Both the spray is bad for the cats and then the actual carbon that comes off can only go into the cats where it gets clogged and causes issues
Hello everyone. Just purchased my 2008 S6 today! I’ve owned a 2010 A5 6speed and I can say this is worlds above that A5! 117k miles. Fully loaded with every option available I believe. ( carbon fiber, lane departure, adaptive cruise, cold weather package, and warm package too). Just had the carbon cleaning done at 112k, and full service records were provided. Currently driving it back to VA from Texas and this thing is extremely comfortable. My wife has been driving too and loves it.
I have been lurking on here for a while, and I give props to each of you C6 owners. After browsing the rest of the Audi forums , this group clearly is the most mature and helpful out there. Maintenance and modification specifically. All the information helped me with my purchase greatly. I can’t wait to start modding. No APR lol JHM all the way. And the heat soak is real on this car. You really can cook an egg on it 
. Here’s a pic of the new pickup and I look forward to learning and contributing to the group. !
Welcome welcome welcome.
I updated your picture as it wasn’t listed in your original post. The car looks fantastic. Always great information here. Lots of super helpful members. Then all of the techs and certified actual mechanics its the place to be if you own an S6 or S8.
Mod wise all I have seen is that anyone that gets or even talks APR and not bashing APR for anything. But anyone that gets or talks an APR Tune over the JHM tune CLEARLY HAS NO FUCKING IDEA what their talking about or doing. I don’t know how many times it needs to be shown that the APR Tune is no faster than stock for people to wise up and not poor that money down the drain.
Remember the JHM intake spacers will pay off big time is cutting down heat and really help add a new level of sustained performance.
Have a fun drive keep us posted.
Welcome, beautiful car!
Thank you.
Welcome, onefasts6!
