Bit about injector flow causing carbon build up isn’t correct. Fsi is direct injection so fuel goes straight into the cylinder instead of the intake. In non direct injection engine the fuel keeps the valves clean, in direct injection you don’t get that. Carbon build up is caused by contaminants in air from PCV and EGR systems. It is a problem in direct injection engines though, not just the s6 and not just Audi.
Agreed - Anything you add to the fuel will have exactly zero effect on the valve carbon deposits. The fuel never interacts with the backs of the valves the way it does in non-direct injected engines. Any kind of fuel additive is basically just snake oil. You need an air intake-based cleaner like CRC 05319 GDI IVD Intake Valve & Turbo Cleaner. There are a ton of videos on here about how to to it. Follow the instructions on the can. It's very easy. I've done it on both of my vehicles. It definitely works but you'll swear you have destroyed your engine after you do it. SUPER SMOKEY AND RUNS TERRIBLY FOR A FEW MINUTES! The easiest way to wedge your gas pedal (read instructions on can) is to put your seat all the way back, cut a stick long enough to reach the pedal, then scoot your seat forward to wedge the stick. Even easier with power seats. A quick blip of the seat switch makes it easy to give it just a little more gas.

I would like to mention for everyone who is watching: I own a 2009 Audi S6, bought it from my roommate for $10k who bought it from a projects guy in Oceanside, CA, where it spent most of its life. I've owned it for almost a year now, and just ticked it over to the 100,000 mi mark. I've ran into all of the issues the guy mentions here- I have replaced all coils/plugs, replaced the intake manifold with the JHM Motorsport option, which I highly recommend (it has Audi's 2nd version, metal flaps instead of plastic ones, helping the issue.) I've also replaced the high-pressure fuel pumps. This was all done by a shop- I have done the oil myself 4 times by now, and also replaced the alternator belt (called the accessory belt) also by myself, without taking the radiator frame completely off. Altogether roughly $4-5k in overall preventative maintenance. The misfiring and unhealthy power characteristics is exactly what symptoms will surface from these issues, I can confirm from my ownership experience. The only thing he didn't mention that I feel like is important to know about the S6's maintenance which I will have to get done on mine: is the upper oil pan. Most oil leaks from this car are not a huge concern and are likely not an extremely expensive fix, but the upper oil pan from what I've been told requires an engine-out service. Other things I will need to have done: Windshield washer pump is not working, the left headlight intermittently doesn't work ("Dipped left headlight"), excessive camber wear (very likely upper control arms), and front pads/rotors. I will also probably want to look at the timing chains if I have that engine-out service done. Other than that, it is running and working perfectly. I daily drove it for 3 weeks when my friend borrowed my Acura, and have put nearly 10k miles on it since I owned it. I put 91-octane in it every single time, and I do max it on occasion. And YES, I do plan to put a louder exhaust on mine. If you do buy one of these cars, also buy some sort of OBD scanning tool that reads VW/Audi's VAGCOM protocol. I recommend OBDEleven, I bought a pro-version reader from ebay for $50. It is a NECESSITY. When test-driving it, try the three different trans modes. I use D for cruising, S for fun, and I rarely use the manual mode... pretty much just to hear the engine on a downshift if I want. If you're seeking a quick manual shift paddle-shift car, you will likely not want this car. If you're afraid of the maintenance: I bought $21 rear brake pads from O' Reilly's and replaced them myself in 2 hours. I replaced the alternator belt(a $17 part) in about 5 hours, a long time but I was constantly googling and being careful with taking stuff apart. I'm sure that's how long book time is, which would have been $600 in labor if I took it to a shop. The oil can be done in just under an hour once you know how to do it. YES, there are more expensive repairs you will want a shop to do, such as the intake manifold and any engine out service. But if you are a sharp car owner, and you have a VAGCOM reader, you'd be surprised how much money you can save. He mentions the E60 M5, a car I also adore... the Inline-5 and V10 engine note I've always loved and the functionality/sportiness of a sedan. I would love to drive an E60 M5 someday, no doubt... but of the two, the S6 is the car I would OWN.
I'll throw out there that one other common issue is leaking cam phaser seals. Very quick and easy to DIY. Check those first if you are dripping oil. It drips back and can make it look like a leaking oil pan gasket. It's hard to see without being under it on a lift, but the cam seals can be seen under the hood, or at least felt by hand if you reach back there.
Have had an 08 S6 for two years. In that time, I’ve replaced: the intake manifold, oxygen sensors(twice), replaced the Air injection pump, and did a carbon cleanup. I love this car, it’s been a bit expensive, but worth it IMO.
@@Drogas3653 I don’t own it anymore. It became too expensive to maintain. Fix one thing then another issue pops up right away. I have a 09 4Runner now, and couldn’t be happier.
Probably the most informative Audi video I’ve seen to date. I’m about 6 months away from making a purchase and it’ll either be a clean S6 or an S8 and this video has helped me tremendously. Thank you for making informative videos of substance w/out the fluff.
@@MkSwampy may i ask where you're from? Here in germany there's just so many of them so they all go low on the price. They're 15k here and how much would they cost in your country?
@@ffews yes indeed. I have had just 1 repair to do which was the power steering pump; but as long as you service regularly it will treat you well...also you get mad clout for owning this rarity,
It's a twin turbo.... makes the same HP stock as the V10 but allows for tuning and turbo upgrades that allow insane power gains. You CANT do anything to make the V10 faster. A twin turbo V6 on the other hand, just a stage 2 tune will gain 130hp+ and turbo upgrades with stage 3 file will produce 800+ hp.
@@imob9657 you absolutely can do things to make the V10 faster- my auto mechanic said he was able to figure out how to unlock hidden RS6 features in the car's ECU, such as fuel enrichment, which by itself will beef a few dozen more HP in the high rev ranges. Computer mods alone I'm sure can harness hundreds of HP just by itself, and I'm not exaggerating. The main reason it's not done is because of how ridiculous the engine packaging is... a lot of serious mods or even minor ones would require several hours of labor and extensive computer knowledge to tear the car apart, and make sure the car's computer doesn't freak out. Not just with newer cars but the reason car modders adore smaller engines is because of the turbos, ECU mods are typically less annoying and there's less at stake when things go wrong (10 coil packs versus 6). There's also a lot more part sharing with cars in that range, the S6's gearbox is only shared with other executive sedans and I dont think a beefier gearbox or manual swap has been tried. The 4F platform S6 is a tough car to work on. But given enough money and expertise- someone could absolutely get a lot more HP out of the motor. But I honestly will want to leave it mostly as is- because the way Audi set it up is to make sure it lasts and doesn't grenade itself. Its plenty fast and a thrill to drive as it is, it just needs to be LOUDER...!
@@Medessec he is lying to you. Very few mechanics know how to code ECU and write tunes. You don't just find hidden stuff in the ECU you have to unlock it and rewrite the software.
a 35-50 dollar oil catch can kit is all you need to fix carbon build up. i have a passat with an fsi engine, and ive never had to worry about the carbon build up problem on the intake valves, as long as i had the catch can installed
Most everything he says is correct. Bought car on the cheap at 75k four years ago and first thing I did was miltek exhaust. At 85k had to replace bushings, control arms, rotors. At 95k really got into the engine. Had to replace some vacuum lines, water pump, had “fluid migration” = coolant was leaking onto wiring harness and traveling ECwU turned out ok which was the main thing, replaced some o rings near the valley, did a carbon clean, and swapped for some aftermarket lambo headers. Rough start and idle went smooth as a cucumber and felt like a completely new car. To this dudes point nothing to major but even the smallest of things can cost a shit ton. Note: my S6 is not my daily just the date night and country road fun car.
You know I have to ask, “aftermarket lambo headers”? You can’t just mention that with no details haha! Where’d you get them/how was fitment/how’s it sound?
I just happened upon this video as I was looking for information on issues that these cars have. I know the 4.2l V8 cars have their tensioner, chain, chain-guide issues so I figured this car wouldn't be any different. My father wants a cool, non-flashy car with some power to drive daily and the S6 fits his needs and wants. The newer ones are either trashed or they're still super expensive. I think your video convinced me to find him a clean C6 S6. Thank you for the time and effort you put into this video for us looking for these niche cars.
I’m really glad that it helped you. Hope you guys enjoy your S6, just be very picky about the one decide on! Better to wait and find an extremely well maintained car.
Good video, only misleading comments are about driving the car hard, this will not reduce carbon buildup. I've got 125K on my 2008, I bought it with 40K eight years ago. These cars are a blast to drive and make great sounds. JHM is the shop that has paid some attention to this platform, have some good mods available.
When you mess with a C6 S6 or A6, you will be in for headaches due to the electrical problems this car always seems to have. Your dash will light up with warnings out of the blue. Tail light warnings, when they work, Emergency Brake warning, yet it works perfectly fine.
Nicely done and covers most of the bases. The one potential mind melter that you failed to mention are the timing chain tensioners. While the V10 hasn't suffered as badly as the 04-06 4.2 V8s they do still suffer failures sometimes. The repair cost to that is nothing short of staggering.... hmmm... do I want to fix the timing on my V10 Audi S6 or buy a small island in the tropics? ;-) Steering column control module failures were also an issue on the C6 A6/S6 line. Only other comment (which has been covered by others) is that the driving style doesn't impact your carbon build up. It's the fact that the injectors don't wash over the valves to keep them clean. A catch can might help prolong the service intervals although a nicely functioning stock PCV system doesn't do a terrible job. The water / meth injection into the air intake path sounds plausible to me if starting on a freshly de-carboned engine. I'd be hesitant on a high mileage car as I don't want any of the carbon deposits going through the system and potentially causing other issues.
My 2010 Toyota Sequoia had an intake manifold issue similar to this which required the entire thing to be replaced. Like this It didn't "kill" the car, but essentially it drove in limp mode and couldn't get above 40 mph. Getting it fixed was about $2800. Now, Toyota being Toyota, issued a TSB and warranty extension on it and would replace it for free on any vehicle under 10 years old and under 150k miles. Good luck getting Audi to offer up something like that on a known problem issue.
I love you for this video. I have an A6 C6 and I’m come a cross these problems which I been able to fix since I been working on cars since single digits. Thanks for the confirmation
Can anybody else confirm this. Most cars my pops has driven ended up getting over 200000 miles and I promise you he never floored it. Does having direct inject mean something here?
I have an obsession with v10s and idk why. I'm still debating on buying my dream car a 2010 m6 with the last year of the v10 but damn the maintenance is killer.
@@michaelgomez5392 Do not be scared, just don't trust every mechanic with your money, use youtube for diagnose before spending money on repair. I drive only Audis all my life, and this one is the best buy ever. I didn't even know what i bought until I started living with it, never even seen V10 before. In 3 years repaired - 1 injector, 1 spark plug, cabine ventilator, 1 xsenon balast and cleaned carbon inside the engine. It does not brake, just drive it normal ( it's not a race car ) and it will go 1M miles 100%. Many people say that those models of Audi S6 and S8 are the last good cars that audi made. My wife has an Audi A4 2.0tdi 2016- with that shit every month something is wrong, and the driving is terrible. oh, and: don't buy with bang&olufsen and ceramics brake and you will be ok, those are brutally expensive. Every service you need 11,5L of oil, oil filter and 2 bigass air filters and you are good to go for 30k km :)))
@@michaelgomez5392 I really hope you do, send pictures :))) on the test drive if you will go to a tunnel, better have money prepared, because the car will go home with you that day.

'' hehehhe
@@davorin5428 thanks for that great info!!! I have bought a 2009 S8 with about 108 K km, and am thinking about how best to treat it to be reliable. Scary stories about flaps breaking, manifolds failing, etc. Absolutely love the car, and I’ve driven/owned many cars 😄. Thanks for your inputs, very helpful. Would be great to reach out through email to compare notes. Reply back to this comment if you’re open to that….thanks. Regards, Steve
Another thing to watch for is the transmission, the 400 lb•ft torque absolutely kills the old 6-speed step-tronic transmission if you launch it too much, other than that this car is pretty much bulletproof. I’m looking to sell mine in 5-6 months because I want to move up to a S7.
Bought a 3.2 FSI Cabriolet. Didnt know the intake was broken when I bought it. Am still on the hunt for a second hand one. If your buying one of these make SURE the unit has been replaced and save yourself the hassle!!!
Actually seafoam works if done properly , drop 1/4 in the oil crank , half or full bottle in fuel tank and the run a bottle in the vacuum lines . I had 2013 s4 always this kind of maintenance since I bought it , till the end is when I sold it at 95k miles .. I did this routine every 10k miles and always added half a bottle in the fuel tank every oil change . ( I did this on all three of my vehicles ) a mini cooper which is know for high carbon clean up , my s4 and my Honda s2000 . This routine added to your normal interval maintenance will help alot in the long run . It will actually save you alot more going to the shop and doing a walnut blaster ( although a walnut blaster is a very well know solution ) doing this specific routine will help prevent the build up . To also add my s4 was high modified and we all know highly modified vehicles will have the most carbon build up. Never looked back at adding seafoam to all my vehicles .
I had a retainer pin drop from the intake and get caught on the back of one of the valves, and another catch a bunch of plastic on the back of another valve. I'd say I got lucky, flap delete is a must on these cars
I own a A6 c6 the 2.8 fsi 3yrs now and no problems and i stay in Africa where the back up isnt so good but iam shopping for the s6 v10 but still keeping my v6
Thanks, very informative! I just bought a 2008 S8, and had some initial concerns about reliability. Mine is very low mileage (@ 40K miles), so I'm not sure how much it actually got driven. I have a short commute, so it doesn't allow me much time to rev, so I think I need to take it out for longer drives now and then to give it some rev's. Useful threads to include as well! Really appreciate the info, and beautiful car--nothing sounds like this engine when driven with vigour :-).
@@BuzzytheBlue Thanks, it absolutely is gorgeous, a unicorn (also APR Stage 2 and Milltek). Just got back from a drive, thanks for the inspiration :-). I'll keep an eye on your channel, please keep the content coming!
@@steveb2893 *when apr literally has never sold a stage 2 option for the c6-s6/d3-s8 platform but the RUclipsr got suckered into replying to the comment anyway*
@@jy5960 Actually, I found an issue with it that I couldn't diagnose and the seller had no ability to rectify either. It had a weird miss happening when I rev'd it out over 5300 rpm--it would actually stutter and miss, then would be fine higher in the rev range. It happened fairly often, and I didn't have the funds or the patience to pursue the cause. If it hadn't been for that, I would definitely have kept it, because the car is amazing. I have not read of this issue anywhere on the forums, so it appears to have been unique to this car. I'm still driving my old D2 S8, just passed 300K km and still running strong. Good luck with your car, and make sure to test it out through the whole rev range just to be sure.
I had a 2007 S6 , Loved it, loved the sound , but the transmission was always its downfall. Sluggish at times denying down shifts, but sometimes it was ok. Very slow gear changes in manual mode. After I sold it I purchased a 2011 Audi A8L 4.2L and absolutely love it. Yes it has less HP, but I swear it feels faster with its zf8 speed trans and of course superior ride quality as the S6 was very over sprung in stock form. Next car in my sites is a 2015 A8L 4.0T soon. The 4.0T is a absolute beast and very underrated in HP by Audi. Few mods and you can easily beat a stock 2015 S8.
Got myself one of these for a pretty good price. It has a new OEM intake manifold, and timing chains. Just need to fix the darn oil+coolant leaks and it should last me a good while. Only got 73k miles on the whole car.
Nice video, however your theory of carbon build up is incorrect. Instead of the strength of the fuel spray causing/removing carbon build up, it is actually temperatures that either allow for or reduce oxidation of the carbon. I'd recommend watching engineering explained latest video about carbon build up. Otherwise, great video!
Great video. Next one should be about all of the benefits we've gleaned from switching to the full JHM suite. Regarding carbon buildup, there's a solution, but the company that produces the solution hasn't been great with marketing. Hopefully we can remedy that and let the car world know we exist.
So there’s no concerns with the infotainment, navigation, gauge cluster or driver info display, hvac controls, window switches/motors, lock actuators, or other gremlin breeding areas?
At least not it my person experience. Even with one with nearly 200,000 miles. If anything, I think the C6 generation Audis were built a bit better than the C7 that came after. Generally they feel better put together than BMWs of the same era (I owned an E60 5-Series). This is all anecdotal of course and very dependent on how the car was maintained/treated.
I would love to get one of these but a kid in high school i dont know if i want to get it if its not reliable also how much would it be too just keep it running for a year
This definitely isn’t a great first car truthfully, unless you have a LOT of disposable income if/when it needs something or you have serious mechanical skills and access to a lift.
I'm very close to buying the 08 or 09 S8. Did the engine get better in that last model yr? I know the 07 was the first yr for the V10 and normally the kinks have to be worked out.
The Mercedes M272 (V6 350) and M273 (V8 550) have this same intake manifold issue, there are replacement billet flaps you can buy for bout $160 rather than buying a a brand new intake manifold (anywhere between $500-$750) is there no metal option to replace the plastic flaps with on these Audi's?
I haven’t been able to find anyone that has done so, nor replacement flaps you can purchase for the S6. If that was an option I doubt anyone would be buying the JHM manifolds or OEM replacements. Just another example of there being a minimal amount of aftermarket support for them.
It's a reason to get a bmw or benz vs. audi. Fewer cars overall, less forum support, fewer aftermarket part suppliers. See more at www.quora.com/Which-one-is-better-Audi-or-BMW/answer/Jason-Taylor-16 .
Buzzy! Amazing video once again - love your approach and quality of content. Very informative. If you ever want to come down to Philly you are welcome to review any of my machines - I think you’d enjoy the differences between them... 1. Track prepped Z4 MCoupe 2. Spec e36 M3 3. VW 1.8T GLI 4. 911 997 TT 5. Cayenne 957 TT
Thank you man I really appreciate that. Next year I may really consider taking you up on that offer, that’s quite the line up and would make for a great set of videos. Thanks again.
So this is much more reliable than the M5? I love the sound and performance of the V10 but I the constant horror stories and credit card suicide trying to keep them running scares the ish out of me 😟
Significantly more reliable than an E60 M5, yes. I wouldn’t even consider an E60 unless I had $4000-6500 worth of repair/preventative maintenance funds. Whereas a well maintained S6 is typically free of such eye wateringly expensive maintenance items.
Heavy and huge amounts of drivetrain loss. Fun and special daily drivers but plenty of faster cars out there. Keep in mind a lot of them rolling around are probably down huge amounts of power because few people maintain them properly lol (carbon buildup).
The maintenance of the car makes a huge difference. Most owners picking them up these days don't maintain them properly. carbon buildup and other issues cause a big loss in power. Also if they have it tuned, exhaust, gutted cats, etc, it makes a huge difference in performance. ruclips.net/video/4rm0sk58B5U/видео.html
Others may steer you away from an S6 in general but I think that’s a steal. Budget some money for future maintenance with an independent shop that knows them well, and enjoy. I’d go for it.
I had an 08 a4 with 3.2 and it had all the problems you said with the v10 I wish I had found this video before I traded it in. Why is this stuff not common knowledge I scoured audi forums to help me but found little to no info like this.
I owned one and it cost $23,000 in one year in maintenance, I got an aftermarket warranty and sold the car after 12 months, It was ridiculously expensive to fix
Some good info here but also some nonsense. The whole chat about winding the engine out do that the larger amount of fuel can clean the intake valves? These engines aren't port injection... The fuel isn't introduced before the back of the intake valve, they are direct injection, the fuel nozzle is inside the cylinder. This is exactly why carbon build up happens to begin with. No matter how hard you drive it the fuel isn't going to magically find its way out of the combustion chamber to clean the back of the intake valves.
The carbon build up section is incorrect and completely misleading. infact driving these cars hard could actually cause MORE carbon build up. The carbon buildup is from the pcv and egr system contaminants on the back side of the valve because there is no fuel to wash them away as fuel is squirted directly into the combustion chamber. Driving hard creates more crankcase ventilation therefore more blowby into the intake manifold. The Audi pcv system isn't too bad but they need to be run warm. This is the same for most direct injection engines. Short regular trips is the absolute killer.
Found one for sale down the road for $14,000 with 121,xxx miles on it. I’ll have to check the car fax a bit more with it having 20 ish service reports and I think 2 owners. What would you say? Something to look at or stay away from?
That sounds like a fair/average price as long as it’s in good shape. Nice that’s it’s only had two owners as well. I’d avoid any S6/8 that’s been passed around too many times lol. I’d also have a PPI done at an Audi shop that knows the V10 well and if it checks out, go for it.
I was under the impression it wasn't specific years as much as specific cars that received it under warranty. It was never a recall, but was addressed on cars that had issues. So it'd have to be confirmed in the cars maintenance records. But I could be misinformed, it's been a while since we had the S6.
@@adamibrahim9488 Sold a few years ago with around 180k miles, was still running and driving awesome. Just time for a change. Probably well over 200k now with the new owner.
@@BuzzytheBlue oh ya that’s understandable, I’m looking into a 2009 s6 right now, it has around 95k so I was trying to find out if the intake manifold was ever updated at all for the later models
To my knowledge the best way to be sure is to have the cars maintenance history proving that it’s been done. Otherwise I’m not certain if the updated manifold/JHM part has a different marking/part # that could be used to physically identify them, there could be but I wasn’t able to find that info.
Nice video but remember its a v10 so it will drink alot of fuel. Its not a economy car so be prepared to pay for fuel abit more often than you would on a regular car.
link* I can't find it either. Seems like they've removed the item from their website as I found a link for it on a forum but when I clicked it said "The page you requested was not found"
I owned one and had the head gasket go out. What he doesn't seem to mention is how much of a leaker these things are . I spent about 7 grand on this car for it to go out on me . Of course I didn't get it from a reputable dealership. No car fax or anything. From what I seen the owner barely did jack on it . Find one with great service history and your going to be OK because this video is helpful . I watched it before I bought my first s6 v10 and yes I'm buying another next week . Anyone who wants one you can't modify it heavily unless u spend in upwards of 25 to 30k and probably more. It's an NA motor . But if your OK with just intake tune and custom exhaust along with flap delete then this is a bad ass car . They can crank out about 450 on 93 or 95 . Race gas tune will get u maybe more I've never done it because I was scared of wear and tear but 450 was good for me to have fun . Oil change and maintenance was wow 😲 😱 but totally worth it if u do your own work or if u can't get a very killer mechanic because a mechanic from audi which is a specialist isn't what u want. Anyway who ever buys this car please enjoy it . There's nothing on the road like it or better sounding
The one in the video had 180k when it was sold, ran 100% but as you said it had accumulated some leaks. It’s a car that you wouldn’t expect to be so durable but they really are when taken care of.
I’m not sure if the RS4 has the manifold failures, but as far as the carbon buildup and general upkeep goes they are quite similar. The 5.2 and 4.2 are quite closely related.
@@BuzzytheBlue Thanks for your answer! I'm a little torn between the two. I like the smaller, lighter, more nible RS4 for driving on mountain roads, but I like the boot space in the S6 Avant for throwing in a bicycle..
Jochem Very different cars, you really can’t go wrong with either one. Although, at least in my market, the RS4 has held its value far better, whereas the S6 can be had for substantially less money. Dollar for dollar the RS4 is the better driving car but the S6 has the nicer interior, more space, and V10 bragging rights.
I’m next in the S6 gang lol paying $12,000 for a 2007 S6 and 98,000 miles with no warning lights and all maintenance records including a new intake and carbon cleaning

Jack Rundle Nothing major, any issues that came about were general maintenance oversights by the pervious owner. Such as waiting too long for carbon cleaning, clogged injectors, and leaks. Generally speaking, major catastrophic failures are nigh on nonexistent with these cars as long as you maintain them well.

Bit about injector flow causing carbon build up isn’t correct. Fsi is direct injection so fuel goes straight into the cylinder instead of the intake. In non direct injection engine the fuel keeps the valves clean, in direct injection you don’t get that. Carbon build up is caused by contaminants in air from PCV and EGR systems.
It is a problem in direct injection engines though, not just the s6 and not just Audi.
Interesting, thanks for the clarification.
You are correct. A way to slow this down is to install a aftermarket catch can on the pcv system.
Water meth intention will steam clean the combustion chamber
@@joes.7536 methanol injection is the only real way to clean it
Agreed - Anything you add to the fuel will have exactly zero effect on the valve carbon deposits. The fuel never interacts with the backs of the valves the way it does in non-direct injected engines. Any kind of fuel additive is basically just snake oil. You need an air intake-based cleaner like CRC 05319 GDI IVD Intake Valve & Turbo Cleaner. There are a ton of videos on here about how to to it. Follow the instructions on the can. It's very easy. I've done it on both of my vehicles. It definitely works but you'll swear you have destroyed your engine after you do it. SUPER SMOKEY AND RUNS TERRIBLY FOR A FEW MINUTES! The easiest way to wedge your gas pedal (read instructions on can) is to put your seat all the way back, cut a stick long enough to reach the pedal, then scoot your seat forward to wedge the stick. Even easier with power seats. A quick blip of the seat switch makes it easy to give it just a little more gas. It's $10 bucks on Amazon: www.amazon.com/gp/product/B00PHNQKR2/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1
I would like to mention for everyone who is watching:
I own a 2009 Audi S6, bought it from my roommate for $10k who bought it from a projects guy in Oceanside, CA, where it spent most of its life. I've owned it for almost a year now, and just ticked it over to the 100,000 mi mark. I've ran into all of the issues the guy mentions here- I have replaced all coils/plugs, replaced the intake manifold with the JHM Motorsport option, which I highly recommend (it has Audi's 2nd version, metal flaps instead of plastic ones, helping the issue.) I've also replaced the high-pressure fuel pumps. This was all done by a shop- I have done the oil myself 4 times by now, and also replaced the alternator belt (called the accessory belt) also by myself, without taking the radiator frame completely off. Altogether roughly $4-5k in overall preventative maintenance. The misfiring and unhealthy power characteristics is exactly what symptoms will surface from these issues, I can confirm from my ownership experience. The only thing he didn't mention that I feel like is important to know about the S6's maintenance which I will have to get done on mine: is the upper oil pan. Most oil leaks from this car are not a huge concern and are likely not an extremely expensive fix, but the upper oil pan from what I've been told requires an engine-out service.
Other things I will need to have done: Windshield washer pump is not working, the left headlight intermittently doesn't work ("Dipped left headlight"), excessive camber wear (very likely upper control arms), and front pads/rotors. I will also probably want to look at the timing chains if I have that engine-out service done. Other than that, it is running and working perfectly. I daily drove it for 3 weeks when my friend borrowed my Acura, and have put nearly 10k miles on it since I owned it. I put 91-octane in it every single time, and I do max it on occasion. And YES, I do plan to put a louder exhaust on mine.
If you do buy one of these cars, also buy some sort of OBD scanning tool that reads VW/Audi's VAGCOM protocol. I recommend OBDEleven, I bought a pro-version reader from ebay for $50. It is a NECESSITY. When test-driving it, try the three different trans modes. I use D for cruising, S for fun, and I rarely use the manual mode... pretty much just to hear the engine on a downshift if I want. If you're seeking a quick manual shift paddle-shift car, you will likely not want this car.
If you're afraid of the maintenance: I bought $21 rear brake pads from O' Reilly's and replaced them myself in 2 hours. I replaced the alternator belt(a $17 part) in about 5 hours, a long time but I was constantly googling and being careful with taking stuff apart. I'm sure that's how long book time is, which would have been $600 in labor if I took it to a shop. The oil can be done in just under an hour once you know how to do it. YES, there are more expensive repairs you will want a shop to do, such as the intake manifold and any engine out service. But if you are a sharp car owner, and you have a VAGCOM reader, you'd be surprised how much money you can save. He mentions the E60 M5, a car I also adore... the Inline-5 and V10 engine note I've always loved and the functionality/sportiness of a sedan. I would love to drive an E60 M5 someday, no doubt... but of the two, the S6 is the car I would OWN.
I'll throw out there that one other common issue is leaking cam phaser seals. Very quick and easy to DIY. Check those first if you are dripping oil. It drips back and can make it look like a leaking oil pan gasket. It's hard to see without being under it on a lift, but the cam seals can be seen under the hood, or at least felt by hand if you reach back there.
Medessec awesome comment
Hey man do you mind sending me an email?
My email address is Emjaybyers@gmail.com
I'd like to inquire about your experience with the S6 v10
Have had an 08 S6 for two years. In that time, I’ve replaced: the intake manifold, oxygen sensors(twice), replaced the Air injection pump, and did a carbon cleanup. I love this car, it’s been a bit expensive, but worth it IMO.
Ryan Buckley how much did all that cost?
Harley Warranty paid for most. Out of pocket I’ve paid about 5K
Really not bad things to replace?
@@ryanbuckley20oh nah, i’ll stick to my reliable Infiniti G37
@@Drogas3653 I don’t own it anymore. It became too expensive to maintain. Fix one thing then another issue pops up right away. I have a 09 4Runner now, and couldn’t be happier.
Probably the most informative Audi video I’ve seen to date. I’m about 6 months away from making a purchase and it’ll either be a clean S6 or an S8 and this video has helped me tremendously.
Thank you for making informative videos of substance w/out the fluff.
Did u end up getting it?

Did you buy?

Has been reliable up until now?
@@ffews yes indeed. I have had just 1 repair to do which was the power steering pump; but as long as you service regularly it will treat you well...also you get mad clout for owning this rarity,
Came here straight after hearing the new S6 (C8) has a V6. It's a sad time we're living in.
Lol, the new S6 in europe has a diesel lol.
It's a twin turbo.... makes the same HP stock as the V10 but allows for tuning and turbo upgrades that allow insane power gains. You CANT do anything to make the V10 faster. A twin turbo V6 on the other hand, just a stage 2 tune will gain 130hp+ and turbo upgrades with stage 3 file will produce 800+ hp.
@@Nahuel16 will make the V10 a collectors item and more sought after 💯
@@imob9657 you absolutely can do things to make the V10 faster- my auto mechanic said he was able to figure out how to unlock hidden RS6 features in the car's ECU, such as fuel enrichment, which by itself will beef a few dozen more HP in the high rev ranges. Computer mods alone I'm sure can harness hundreds of HP just by itself, and I'm not exaggerating. The main reason it's not done is because of how ridiculous the engine packaging is... a lot of serious mods or even minor ones would require several hours of labor and extensive computer knowledge to tear the car apart, and make sure the car's computer doesn't freak out. Not just with newer cars but the reason car modders adore smaller engines is because of the turbos, ECU mods are typically less annoying and there's less at stake when things go wrong (10 coil packs versus 6). There's also a lot more part sharing with cars in that range, the S6's gearbox is only shared with other executive sedans and I dont think a beefier gearbox or manual swap has been tried. The 4F platform S6 is a tough car to work on. But given enough money and expertise- someone could absolutely get a lot more HP out of the motor. But I honestly will want to leave it mostly as is- because the way Audi set it up is to make sure it lasts and doesn't grenade itself. Its plenty fast and a thrill to drive as it is, it just needs to be LOUDER...!
@@Medessec he is lying to you. Very few mechanics know how to code ECU and write tunes. You don't just find hidden stuff in the ECU you have to unlock it and rewrite the software.
a 35-50 dollar oil catch can kit is all you need to fix carbon build up. i have a passat with an fsi engine, and ive never had to worry about the carbon build up problem on the intake valves, as long as i had the catch can installed
Thanks! Just drain the oil tank and put in new oil?
Thats the same modification I did to my bmw 335 also, works great
How do you install or even order it
Is that the issue? Oil vapors collecting on the valves?
Most everything he says is correct. Bought car on the cheap at 75k four years ago and first thing I did was miltek exhaust. At 85k had to replace bushings, control arms, rotors. At 95k really got into the engine. Had to replace some vacuum lines, water pump, had “fluid migration” = coolant was leaking onto wiring harness and traveling ECwU turned out ok which was the main thing, replaced some o rings near the valley, did a carbon clean, and swapped for some aftermarket lambo headers. Rough start and idle went smooth as a cucumber and felt like a completely new car. To this dudes point nothing to major but even the smallest of things can cost a shit ton.
Note: my S6 is not my daily just the date night and country road fun car.
You know I have to ask, “aftermarket lambo headers”? You can’t just mention that with no details haha! Where’d you get them/how was fitment/how’s it sound?
Note to self never drink and comment on shit lol they were just spacers.jhm But the whole set up sounds great! And the car “breaths” so much better.
I just happened upon this video as I was looking for information on issues that these cars have. I know the 4.2l V8 cars have their tensioner, chain, chain-guide issues so I figured this car wouldn't be any different. My father wants a cool, non-flashy car with some power to drive daily and the S6 fits his needs and wants. The newer ones are either trashed or they're still super expensive. I think your video convinced me to find him a clean C6 S6. Thank you for the time and effort you put into this video for us looking for these niche cars.
I’m really glad that it helped you. Hope you guys enjoy your S6, just be very picky about the one decide on! Better to wait and find an extremely well maintained car.
Good video, only misleading comments are about driving the car hard, this will not reduce carbon buildup. I've got 125K on my 2008, I bought it with 40K eight years ago. These cars are a blast to drive and make great sounds. JHM is the shop that has paid some attention to this platform, have some good mods available.
When you mess with a C6 S6 or A6, you will be in for headaches due to the electrical problems this car always seems to have. Your dash will light up with warnings out of the blue. Tail light warnings, when they work, Emergency Brake warning, yet it works perfectly fine.
Nicely done and covers most of the bases. The one potential mind melter that you failed to mention are the timing chain tensioners. While the V10 hasn't suffered as badly as the 04-06 4.2 V8s they do still suffer failures sometimes. The repair cost to that is nothing short of staggering.... hmmm... do I want to fix the timing on my V10 Audi S6 or buy a small island in the tropics? ;-) Steering column control module failures were also an issue on the C6 A6/S6 line.
Only other comment (which has been covered by others) is that the driving style doesn't impact your carbon build up. It's the fact that the injectors don't wash over the valves to keep them clean. A catch can might help prolong the service intervals although a nicely functioning stock PCV system doesn't do a terrible job. The water / meth injection into the air intake path sounds plausible to me if starting on a freshly de-carboned engine. I'd be hesitant on a high mileage car as I don't want any of the carbon deposits going through the system and potentially causing other issues.
My 2010 Toyota Sequoia had an intake manifold issue similar to this which required the entire thing to be replaced. Like this It didn't "kill" the car, but essentially it drove in limp mode and couldn't get above 40 mph. Getting it fixed was about $2800. Now, Toyota being Toyota, issued a TSB and warranty extension on it and would replace it for free on any vehicle under 10 years old and under 150k miles. Good luck getting Audi to offer up something like that on a known problem issue.
I love you for this video. I have an A6 C6 and I’m come a cross these problems which I been able to fix since I been working on cars since single digits. Thanks for the confirmation
a car where you are recommended to red line it once per drive?? fk yea im in!!!
Can anybody else confirm this. Most cars my pops has driven ended up getting over 200000 miles and I promise you he never floored it. Does having direct inject mean something here?
@@Rois300 this isn't true for direct injection. Direct inject goes straight into the cylinder never even touched the valves.
"It's true Officer, BuzzytheBlue said so"
I have had one and loved it. No major problems whatsoever.
Sold our last one with around 180,000 miles, had no issues during our ownership at all. Surprisingly reliable cars.

@@michaelgomez5392 Do not be scared, just don't trust every mechanic with your money, use youtube for diagnose before spending money on repair. I drive only Audis all my life, and this one is the best buy ever. I didn't even know what i bought until I started living with it, never even seen V10 before. In 3 years repaired - 1 injector, 1 spark plug, cabine ventilator, 1 xsenon balast and cleaned carbon inside the engine. It does not brake, just drive it normal ( it's not a race car ) and it will go 1M miles 100%. Many people say that those models of Audi S6 and S8 are the last good cars that audi made.

No nonsense. I like you. Subscribed.
Another thing to watch for is the transmission, the 400 lb•ft torque absolutely kills the old 6-speed step-tronic transmission if you launch it too much, other than that this car is pretty much bulletproof. I’m looking to sell mine in 5-6 months because I want to move up to a S7.
how much u want
9K
Bought a 3.2 FSI Cabriolet. Didnt know the intake was broken when I bought it. Am still on the hunt for a second hand one. If your buying one of these make SURE the unit has been replaced and save yourself the hassle!!!
Actually seafoam works if done properly , drop 1/4 in the oil crank , half or full bottle in fuel tank and the run a bottle in the vacuum lines .
I had 2013 s4 always this kind of maintenance since I bought it , till the end is when I sold it at 95k miles .. I did this routine every 10k miles and always added half a bottle in the fuel tank every oil change . ( I did this on all three of my vehicles ) a mini cooper which is know for high carbon clean up , my s4 and my Honda s2000 . This routine added to your normal interval maintenance will help alot in the long run . It will actually save you alot more going to the shop and doing a walnut blaster ( although a walnut blaster is a very well know solution ) doing this specific routine will help prevent the build up . To also add my s4 was high modified and we all know highly modified vehicles will have the most carbon build up. Never looked back at adding seafoam to all my vehicles .
Excellent video. Hoping to buy a 54k mile S8 next week, this helps a lot
Audi S6 V10 theme song must be ''Barry White - Can't Get Enough Of Your Love Baby''
I had a retainer pin drop from the intake and get caught on the back of one of the valves, and another catch a bunch of plastic on the back of another valve. I'd say I got lucky, flap delete is a must on these cars
I own a A6 c6 the 2.8 fsi 3yrs now and no problems and i stay in Africa where the back up isnt so good but iam shopping for the s6 v10 but still keeping my v6
Thanks, very informative! I just bought a 2008 S8, and had some initial concerns about reliability. Mine is very low mileage (@ 40K miles), so I'm not sure how much it actually got driven. I have a short commute, so it doesn't allow me much time to rev, so I think I need to take it out for longer drives now and then to give it some rev's. Useful threads to include as well!

hey considering an S8 V10 with only 58k miles on it, any thoughts you can share after 2 years?
@@jy5960 Actually, I found an issue with it that I couldn't diagnose and the seller had no ability to rectify either. It had a weird miss happening when I rev'd it out over 5300 rpm--it would actually stutter and miss, then would be fine higher in the rev range. It happened fairly often, and I didn't have the funds or the patience to pursue the cause. If it hadn't been for that, I would definitely have kept it, because the car is amazing. I have not read of this issue anywhere on the forums, so it appears to have been unique to this car. I'm still driving my old D2 S8, just passed 300K km and still running strong. Good luck with your car, and make sure to test it out through the whole rev range just to be sure.
I had a 2007 S6 , Loved it, loved the sound , but the transmission was always its downfall. Sluggish at times denying down shifts, but sometimes it was ok. Very slow gear changes in manual mode. After I sold it I purchased a 2011 Audi A8L 4.2L and absolutely love it. Yes it has less HP, but I swear it feels faster with its zf8 speed trans and of course superior ride quality as the S6 was very over sprung in stock form. Next car in my sites is a 2015 A8L 4.0T soon. The 4.0T is a absolute beast and very underrated in HP by Audi. Few mods and you can easily beat a stock 2015 S8.
The sounds this car makes are pure aural sex.

Looking at one of these for 7k with all the issues addressed. Would be my secondary fun car. Wouldn't put too many miles on it. Worth it?
Yes!
Found this vid while doing research on the car. Subbed!
Nice video, however your theory of carbon build up is incorrect. Instead of the strength of the fuel spray causing/removing carbon build up, it is actually temperatures that either allow for or reduce oxidation of the carbon. I'd recommend watching engineering explained latest video about carbon build up. Otherwise, great video!
Already have a comment pinned with that correction haha. Thanks for watching and for pointing that out.
Great video. Next one should be about all of the benefits we've gleaned from switching to the full JHM suite. Regarding carbon buildup, there's a solution, but the company that produces the solution hasn't been great with marketing. Hopefully we can remedy that and let the car world know we exist.
What's the name of the company?
You need to add an overlay correcting the carbon buildup stuff to the video!!
The video could be good if you correct the reason for this engine to get carbon deposits. This is very important to know about this car.
It’s already a pinned comment. Thanks.
So there’s no concerns with the infotainment, navigation, gauge cluster or driver info display, hvac controls, window switches/motors, lock actuators, or other gremlin breeding areas?
At least not it my person experience. Even with one with nearly 200,000 miles. If anything, I think the C6 generation Audis were built a bit better than the C7 that came after. Generally they feel better put together than BMWs of the same era (I owned an E60 5-Series). This is all anecdotal of course and very dependent on how the car was maintained/treated.
Can u please make a video about rs6 2009 saloon in deep detail about the negatives and the positives thank you.
I would love to get one of these but a kid in high school i dont know if i want to get it if its not reliable also how much would it be too just keep it running for a year
This definitely isn’t a great first car truthfully, unless you have a LOT of disposable income if/when it needs something or you have serious mechanical skills and access to a lift.
I'm very close to buying the 08 or 09 S8. Did the engine get better in that last model yr? I know the 07 was the first yr for the V10 and normally the kinks have to be worked out.
The Mercedes M272 (V6 350) and M273 (V8 550) have this same intake manifold issue, there are replacement billet flaps you can buy for bout $160 rather than buying a a brand new intake manifold (anywhere between $500-$750) is there no metal option to replace the plastic flaps with on these Audi's?
I haven’t been able to find anyone that has done so, nor replacement flaps you can purchase for the S6. If that was an option I doubt anyone would be buying the JHM manifolds or OEM replacements. Just another example of there being a minimal amount of aftermarket support for them.
It's a reason to get a bmw or benz vs. audi. Fewer cars overall, less forum support, fewer aftermarket part suppliers. See more at www.quora.com/Which-one-is-better-Audi-or-BMW/answer/Jason-Taylor-16 .

Awesome - lets try to touch base in the spring. Cars are getting ready to hibernate for winter :)@@BuzzytheBlue
very handy info.
so what does it actually do to the gallon , as a daily drive.
I avg 16-17mpg in daily highway traffic. Up to 20mpg on road trips.
So this is much more reliable than the M5? I love the sound and performance of the V10 but I the constant horror stories and credit card suicide trying to keep them running scares the ish out of me 😟
Significantly more reliable than an E60 M5, yes. I wouldn’t even consider an E60 unless I had $4000-6500 worth of repair/preventative maintenance funds. Whereas a well maintained S6 is typically free of such eye wateringly expensive maintenance items.
This was a great review! I look forward to one day owning an S6!
My auto G35 pulled on one until 100mph everytime from a 60 roll. They aren’t as quick as I thought they would be.
Heavy and huge amounts of drivetrain loss. Fun and special daily drivers but plenty of faster cars out there. Keep in mind a lot of them rolling around are probably down huge amounts of power because few people maintain them properly lol (carbon buildup).
The maintenance of the car makes a huge difference. Most owners picking them up these days don't maintain them properly. carbon buildup and other issues cause a big loss in power. Also if they have it tuned, exhaust, gutted cats, etc, it makes a huge difference in performance.

I had an 08 a4 with 3.2 and it had all the problems you said with the v10 I wish I had found this video before I traded it in. Why is this stuff not common knowledge I scoured audi forums to help me but found little to no info like this.
JHM's website doesn't seem to have their intake manifold listed anymore. Not sure if they've discontinued making them. Sad day.
Yikes, thats definitely unfortunate news. For anyone in the market, it would be worthwhile to contact them to confirm.

I owned one and it cost $23,000 in one year in maintenance, I got an aftermarket warranty and sold the car after 12 months, It was ridiculously expensive to fix
That sounds like a lot, but I'm assuming almost everything was replaced or the engine was dropped a couple times.
@@jtherealtor yeah pretty much everything got replaced, they had to take the engine out completely on several occasions.
Some good info here but also some nonsense. The whole chat about winding the engine out do that the larger amount of fuel can clean the intake valves? These engines aren't port injection... The fuel isn't introduced before the back of the intake valve, they are direct injection, the fuel nozzle is inside the cylinder. This is exactly why carbon build up happens to begin with. No matter how hard you drive it the fuel isn't going to magically find its way out of the combustion chamber to clean the back of the intake valves.
The pinned comment offers this exact correction. Thank you regardless.
Actually just trimmed that portion of the video out, wish I’d known that was possible years ago lol.
Looking at an 08 S6 V10 and a 08 cl600 TT V12, which is the better buy for reliability and daily driving?
Oh god don’t get the 600 😂 If the S6 has somewhat steep maintenance the TTV12 will have you selling kidneys. S6 is far easier to maintain.
The carbon build up section is incorrect and completely misleading.
infact driving these cars hard could actually cause MORE carbon build up.
The carbon buildup is from the pcv and egr system contaminants on the back side of the valve because there is no fuel to wash them away
as fuel is squirted directly into the combustion chamber.
Driving hard creates more crankcase ventilation therefore more blowby into the intake manifold.
The Audi pcv system isn't too bad but they need to be run warm.
This is the same for most direct injection engines.
Short regular trips is the absolute killer.
Great video. Thank you
So we got a S6 but not the RS6 in America I wonder if our neighbors to the North got the RS6?
Which is more reliable engine Audi S6 V10 or Bmw E60 v10 ?
Thank you this helped me out.
Found one for sale down the road for $14,000 with 121,xxx miles on it. I’ll have to check the car fax a bit more with it having 20 ish service reports and I think 2 owners. What would you say? Something to look at or stay away from?
That sounds like a fair/average price as long as it’s in good shape. Nice that’s it’s only had two owners as well. I’d avoid any S6/8 that’s been passed around too many times lol. I’d also have a PPI done at an Audi shop that knows the V10 well and if it checks out, go for it.
Well made and informative review
how many miles have you put on yours? can you please explain violent idle? the rpm are high? and what is shaking
Sounds like carbon buildup causing misfires. Probably needs carbon cleaned and the injectors checked.
Can anyone here tell me if this engine will work in a huracan? Thinking about taking on a project and I’m tryna do it budget as possible
Solid info
Excellent video!
Do you or anyone else here know what years Audi updated the intake manifold flaps to the new ones without the plastic ones?
I was under the impression it wasn't specific years as much as specific cars that received it under warranty. It was never a recall, but was addressed on cars that had issues. So it'd have to be confirmed in the cars maintenance records. But I could be misinformed, it's been a while since we had the S6.
You don’t have it anymore?
@@adamibrahim9488 Sold a few years ago with around 180k miles, was still running and driving awesome. Just time for a change. Probably well over 200k now with the new owner.
@@BuzzytheBlue oh ya that’s understandable, I’m looking into a 2009 s6 right now, it has around 95k so I was trying to find out if the intake manifold was ever updated at all for the later models
Do you have any info on the codes that would show that the intake manifold has been replaced with the updated version?
To my knowledge the best way to be sure is to have the cars maintenance history proving that it’s been done. Otherwise I’m not certain if the updated manifold/JHM part has a different marking/part # that could be used to physically identify them, there could be but I wasn’t able to find that info.
Nice video but remember its a v10 so it will drink alot of fuel. Its not a economy car so be prepared to pay for fuel abit more often than you would on a regular car.
Very helpful video! Thanks for posting. I am about to go check one of these out.
Good info thank you.
Thanks buddy, good video. Subscribed!
Can you link the JHM intake
link* I can't find it either. Seems like they've removed the item from their website as I found a link for it on a forum but when I clicked it said "The page you requested was not found"
@thanks for the spell check
So, do you think an Audi S6 with 99 000 miles, is going to be relaible ? Because I am think about to buy it.
How much have you spent so far on repairs.
I owned one and had the head gasket go out. What he doesn't seem to mention is how much of a leaker these things are . I spent about 7 grand on this car for it to go out on me . Of course I didn't get it from a reputable dealership. No car fax or anything. From what I seen the owner barely did jack on it . Find one with great service history and your going to be OK because this video is helpful . I watched it before I bought my first s6 v10 and yes I'm buying another next week . Anyone who wants one you can't modify it heavily unless u spend in upwards of 25 to 30k and probably more. It's an NA motor . But if your OK with just intake tune and custom exhaust along with flap delete then this is a bad ass car . They can crank out about 450 on 93 or 95 . Race gas tune will get u maybe more I've never done it because I was scared of wear and tear but 450 was good for me to have fun . Oil change and maintenance was wow 😲 😱 but totally worth it if u do your own work or if u can't get a very killer mechanic because a mechanic from audi which is a specialist isn't what u want. Anyway who ever buys this car please enjoy it . There's nothing on the road like it or better sounding
The one in the video had 180k when it was sold, ran 100% but as you said it had accumulated some leaks. It’s a car that you wouldn’t expect to be so durable but they really are when taken care of.
quality freaking vid.
What about the timing chain how long does those last
Are the issues similar to those on the B7 RS4, sans the auto/manual difference of course.
I’m not sure if the RS4 has the manifold failures, but as far as the carbon buildup and general upkeep goes they are quite similar. The 5.2 and 4.2 are quite closely related.
@@BuzzytheBlue Thanks for your answer! I'm a little torn between the two. I like the smaller, lighter, more nible RS4 for driving on mountain roads, but I like the boot space in the S6 Avant for throwing in a bicycle..
Jochem Very different cars, you really can’t go wrong with either one. Although, at least in my market, the RS4 has held its value far better, whereas the S6 can be had for substantially less money. Dollar for dollar the RS4 is the better driving car but the S6 has the nicer interior, more space, and V10 bragging rights.
I’m next in the S6 gang lol paying $12,000 for a 2007 S6 and 98,000 miles with no warning lights and all maintenance records including a new intake and carbon cleaning
Did you buy? How has it been so far?
lamborghini V10 and reliability ? LULZ
but hey, who give a damn, that thing is a freakin' wheeled missile.
What's the song you got playing at the start?
My uncle owns a S6 C6 but the previous owner put dual single tip exhaust. But it sounds mean and it goes. He has it for 3 years now and no carbon fill up :)
Oh I bet the dual single tips look great when done right. More akin to an RS6 look.
Dude, thank you!
excellent video
And the rs6, can I take these these advise for that car?
completely different engine, so no
theres one listed for 25k with 60k miles and i told the salesguy its a super cool car but truly i dont trust the reliability
Could someone post the link to the fuel additive I can not find that and that will help with the carbon build up
Here you go. It’s VW/Audi G17 Additive www.fcpeuro.com/products/fuel-additive-genuine-audi-vw-g001770a2?ads_cmpid=1586103033&ads_adid=62588326769&ads_matchtype=&ads_network=g&ads_creative=298122218785&ads_targetid=pla-338677243666&ttv=2&gclid=CjwKCAjwm-fkBRBBEiwA966fZFJq4mXpyG6R8ksTOmugQfgt2BMpd3Fhv7k5ItetxYCxr2eUa62XOxoCD4AQAvD_BwE
BuzzytheBlue thank you so much so this will definitely help with the carbon build up right and I just did the whole carbon engine clean up put new almost everything in that beast
@@arjelsavage7081 i use CRC 05319 GDI Intake Valve Cleaner just before the oil change - sprayed into inlet manifold exactly as per directions then heat soaked, etc. Checking with an inspection camera through the sparkplug has shown the inlet valve carbon buildup is minor and stable. Nothing like the horror stories you can see with VAG engines online.
It won't do anything. You have to use air cleaner.
Is it safe to assume this applies to s8 of the same era?
Essentially, yes. They have identical drivetrains, just a slightly different state of tune.
Do you own this car how has it been
There’s some great deals on V10 S6’s right now. Cargurus has 7 listed with less than 85,000 miles and under $15k. This 2007 has 55,700 miles with no accidents and an asking price of $13,890. That’s a good price. They have several 2010 and 2011 models too for around $20k.

i own s8 5.2 so and i got all those 4 issues 😅 i think car is approx 300 HP
That's it I'm buying one 😂 😘
Do it before they go up. Still a crazy bargain compared to other interesting cars.
Is this info the same for a V8 S5?
The carbon cleanup still occurs, other than that they have many differences
The intake dont brake , it gets stuck not a expensive fix .
Did you own one? If so do you still have it? If not why did you sell it? I am curious. I actually own a '08 s6 myself
Had two over the years. The last one was sold with almost 180,000 miles. Treated me very well reliability wise. They are amazing cars for the money but it was time for a change and 200,000 mile V10 Audi’s are nigh on unsellable haha.
Oh actually? I’m in the market for an 07 s6 and I wanted to know if you’ve had any real issues with that car
Jack Rundle Nothing major, any issues that came about were general maintenance oversights by the pervious owner. Such as waiting too long for carbon cleaning, clogged injectors, and leaks. Generally speaking, major catastrophic failures are nigh on nonexistent with these cars as long as you maintain them well.
i have had mine for 2 years now, stll have it....it svery rare here in SA so it does turn heads alot. got 82k miles (american unit of measurement) on mine.
