Any thoughts on the timing chain and tensioners? I've read on various forums that they're also a common point of failure. I'm in a similar boat to OP and looking at a '16 S6 with 75k on the clock and am concerned about the engine-out job.
You know I have never quoted one but if that is becoming a point of failure absolutely that'll break the bank. I know on the older 2.0L TSI motors they fail constantly, Never really saw them on the 3.0L S/C motors. I only owned my S6 for about 1 year and 10k miles of driving so fortunately gone before any major catastrophes.
Audi is now recalling S6-S7 and other 4.0 t for replacing oil screen 👏👍. By mid summer 2022 parts should be at Audi dealerships to start fixing these cars and stop the turbo failing issue.
A note to all you fellow C7 owners. I took mine in the shop (Audi dealer) for a suspention issue and she informed me the turbo waranty has been extended by Audi to 120,000 miles or 10 years. I have a '13 S6. So something to ask if your turbos go out and you're not going RS swap. I'm at 118,500 so it probably won't do me any good, lol. In the meantime change oil early, I do every 5k and do a periodic oil flush to keep that screen clean. I used liquimoly at about 90miles and it made brand new oil look like the 5k stuff in 15 minutes.
@@SirDeathstroke Call the dealer and inquire. I can't say for sure but I'd think it would. Side note: Front lower reaward arms from the factory have bad bushings. Powerflex makes a polyurethane for that arm that is fantastic! Much more precise steering and suspention feel. Well worth the upgrade.
Awesome stuff man. I have a 2016 s7 stage 1 APR and I didn’t change the oil screen. Put 30k miles on the car but haven’t driven it too hard. Am I screwed lol?
Not necessarily. I mean the OEM turbos do have a high failure rate so I wouldn't beat yourself up over it lol Just like I tell everyone else be mindful that replacement is just part of owning these cars. It's really a straightforward process. This also creates an opening to upgrade as well :)
I’m doing the same bro , I’ve done a lot researching I am for sure going to grab it as it is my dream car and eventually we will all be electric ( I’m joking i know it’s not that soon but still.) but I’m wondering since they had recalls … will the S7 we are looking to buy have been serviced from those recalls already ?? Especially since we are buying firm a dealership … well I am . I also wonder how we can skip alll stages and immediately go to stage 3 and we never got any other tune done first
how hard is it to service and access the turbo oil screen? and if it is hard, couldn't you buy some aftermarket setup to install a oil screen bypass? In aviation, they use a calibrated spring, and if oil pressure increases due to a clog, the backpressure overpressures the calibrated spring, allowing oil to bypass around the oil pump at the clog. I'm wondering if there's some aftermarket device that would allow you to do that for these audi's
It's a very involved job to remove the oil screen. You can simply remove it or remove it and install the serviceable oil feed line relocation kits. Totally up to you!
Great, informative videos! I’ve read that DSG is a weak point for going stage1+ on 4.0T S6… do you ever see clutch/transmission failures from built S6’s or are the turbos likely to go first? Considering for a 14k ‘18 S6 in the UK 😁
Thanks for checking it out. Yes the DSG is a weak point when you compare it to the stronger ZF8 transmission found in the S8/RS7. Good news is there are clutch upgrades available from SRM.
Honestly I have never heard of a DSG failure. Not saying they don't, but If I've never heard of one failing then it can't be all that often. I'm at 120k and stage 1 since about 70k. I drive it hard.
Seems like no one love the s8. I'm looking to get something nice comfortable and fast. Came across the s8 on car guru and 2013-2015 with 50-100k miles only like 25k. For 520 hp? I just take this to a tuner and try to bullet proof it? Sounds like it can't get more perfect.
@@savagepandaprojects how capable? Stock they are just what I want from a car. Fast, and luxurious. I LOVE luxury. I've heard they can be pretty unreliable, how would I obtain one and keep it out of the shop? How could I beat on it stock and it not break?
Good info. I have the factory 3.0t supercharged b8.5 s5, but its still low mileage.. building it for now, but once Ive had my fun Im probably doing the s8 4.0t swap. Word is 034 might be making a swap kit for it.
@@RG-mt6is the 4.0t can make much larger numbers + turbos. The s5 is limited to around 500-550 at the wheels tops with everything on the market as of now fully ported and everything.. kind of limited by the supercharger/internals/iets.
Svarog performance(on RU-vid) has done some 4.0 swaps. He's in the states and has done a B8.5 S4 and S5. One is a manual too I think👀. I got my S7, but the S5 with a 4.0 would be an amazing drag car and it could take corners damn well👀
People are running 2000+ hp with the almost the same dsg on twin turbo ugr r8’s. There are clutch upgrades and there are axle upgrades. To suit everyone’s horsepower needs
I know this vid is 1yo but, I am in the market trading in my '14 A6 for '14 S7 with 51K Miles. I did see there was a recall on the oil strainer. Is that the same as the "oil screen"? Manufacturer Safety Recall issued NHTSA #22V178 Recall #21H7 OIL STRAINER Status: Remedy Available Locate an authorized Audi dealer to obtain more information about this recall
I have a 2017 c7.5 S6. Stage 1 APR tuned for about a year and a half now and about 20k miles. Car has 67k miles now. No issues yet runs great thankfully so far. I do castrol 5w40 full synthetic every 3k miles to keep the oil as clean as possible and have had the car since about 45k miles, plus had all records of consistent previous maintainance that was done since beginning of vehicles life. I have to think this makes difference with oil screen clog but can't be certain. I did not have any oil screen preventative work done. If turbos go I'll just replace them. Already got the recall letter in the mail as well.
Picked up my c7 RS6 last year. Audi replaced the oil screen as a recall and I've heard the PCV can mess up too so I asked them to replace that at the same time. Good piece of mind 😊
Good thing they just sent out the oil screen recall. Took them 5 days at the dealership to finish my C7.5 S7. Hoping that it solves the turbo failure issue.
I had mine done at 121K on my A8L and there was zero play in the turbos. I now have 136K and it's been on a stage 2 tune for 35K miles. To say 70K miles would have a lot of play in the turbos in nonsense.
@@xartic1608I’ve seen it. Had an RS7 and S8 that needed turbos before 100k. I’m an Audi dealer tech so I did a lot of those recalls. They were gravy on the A8/S8, on the S6/S7 they were super annoying lol
Hi Savage, i own an audi s6 2013 and i want to know if you can recommend what i should do about to avoid turbos failure, i saw some videos but i dont really know how many things i need to do to make the car running safe with the OEM turbos. the car have 48k miles and i think about remove the oil screen but my question is what else i need to change or replace to running well with OEM turbos. (no stages) thanks in advance & i hope you can help me with your feedback. Regards!!
Hello Diego! Yes lots to cover here. Main priority is getting your oil screen TSB done. Turbo failure is very common on these cars so would always budget for that as they may have some play in them and not be covered under warranty/recall. There is another recall for the PCV/oil separator as well so check with your local Audi dealer to see if your car has an open recall(s) for these issues. From a labor standpoint regardless if your dealing with a dealership recall, it would most efficient to have all of these done at the same time (oil screen removal, PCV, turbos, etc) I have a separate video covering my full stage 3 build so be sure to check that out :)
Id stay away from the A8 personally. The 3.0l SC motors are ok but they are very limited in terms of upgradability compared to the 4.0T. They also suffer from oil consumption issues as well.
I’m new to all this , but as I prepare to purchase an s7 2017/18 I’ve done a lot of research and wanted to tune it … I see here you say skip everything and go all the way to stage 3 … 1. What is the oil screen and what video do I watch to know what you’re talking about 2. How do I know or check the health of my turbos when I’m looking to purchase this vehicle in the next 9 months .. 3. Since I’ve searched and realize there’s been a recall on them from 2013-2017 .. should the vehicle have been serviced by Audi since the recall was worldwide ? I know there is a way to check it as I’ve searched it up as well.
Yes also shares many of the same components being another 4.0T car. There are some differences between the 4.0T in the S6/S7/A8 vs S8/RS7. One of the main differences being lower compression ratio.
I have an S6 with 110k miles....been APR stage 2 since 40k miles and the only thing ii have ever replaced was 1 motor mount.. i use only amsoil oil and replace every 5k miles, and do all my services religiously. Stick get on it pretty often
So basically, if im interested in buying a pre-owned 4.0T, I need to make sure the turbos have been changed or new, OR the oil screen has been replaced? Or do you just recommend staying away from the 4.0T all together? I dont want to purchase a vehicle then have to put a bunch of money into it.
Yeah unless your comfortable and fully prepared to spend thousands and thousands of dollars in maintenance and repairs I would not get into this platform. Some have had oil screen replaced under factory recall but the stock turbos on these cars fail so often regardless of the screen was or wasn't replaced you need to anticipate they will need to get done as well. Watch out for oil screen, turbos, PCV, motor mounts, air suspension, etc. I did a separate video about this too. Hope that helps.
You can certainly go bigger if your budget allows. I would be prepared to upgrade the clutch to handle the torque as the DSG is the weak point on this platform. 800hp for sure gonna need it.
@@savagepandaprojects Yeah man. Invest in a good matte leather conditioner. It shouldn’t be that shiny. That being said to each their own and if you like the glossy leather it’s your whip and your choice! Just from factory the leather is muted. At least that’s been the case in my B8 and my B9.5 S4s I’ve owned. Again, beautiful car regardless that shine just threw me a curve ball.
Some later c7.5 models had the revised screen, however this inherently is a design flaw as you can still run into problems so the best course of action is to eliminate the screen/ install oil feed line relocation kit.
Wow you guys really install confidence about this product. I was looking at getting a s7 2017 or newer. But if turbos are going a out before 100k miles I'm just not interested in footing those bills. Lol water pumps, thermostats, turbos, transmission shift linkages valve bodies, high oil consumption, sludge. Sounds like a literal nightmare. Why would anyone want to buy this pos?
Almost every car platform has issues. For the most part these cars are very reliable. A lot of people online try to scare people with all this negative stuff but it really is all about how you maintain the car.
turbos are not a big deal at all... you can find em for 400$ if you know where to look and the install in literally 2-3hrs tops and its fun... ive done it 3xs now... i have a blast building this platform
Hey man! Love the content, I went IE stage 1 ecu and tcu 3 days ago on my 103k original turbo 13 s6 for kicks and wiggles, today during a WOT pull my EPC light came on and I’m sure it was Probably a misfire so going to get scanned tomorrow, but mean time I just ordered a cooler but what do you recommend for turbos? I was thinking SRM +4 or JHM RS7-R turbos and was wondering who you thought, but 100% agree if you are going to do it just go stage 3 the car needs 80% of the parts replaced anyways might as well make them better while you are in there!
Thanks man! Really appreciate the support. Sounds like you are definitely in the market for some new turbos lol I have seen plenty of welll satisfied customers running JHM turbos with APR stage 3 software. Haven't driven a +4 SRM car but they are also popular. For that you would need to run DS1 software. Probably along with the SRM dsg tune. I'm sure that would be a formidable package!
Did you check your plugs? Usually tunes require certain spark plug changes and gaps.. if you have the wrong plugs or gap it can definitely cause misfires under load.
Thanks to Savage Panda Projects for the information. I own a 2016 RS7 stage 2 which was purchased with all work done, at 28,000 miles. This car flies at 42,000 miles now. I added a K&N air filter. Also, replaced those heavy stock wheels with HRE aluminum alloy monoblocks. The wheels reduced unsprung weight probably 10lb or more per wheel. The wheels are polished gold, which admirers claim "those wheels really make it pop". The car is red which is a good contrast with gold. The K&N and wheels together made the felt acceleration much greater. However, the DOWN PIPES made the biggest power gain, excluding stage ONE. Wheels are third on power gain. Note stock turbo's. Stage one is likely; timing advance, richening the fuel mixture and most important increasing the BOOST. Stage II, APR downpipes. The car is ready to produce a lot of gases and needs to exit through downpipes. The downpipes offer more power than your cat back systems however, add the cat-back if you have the $$$. Also, don't forget the all important X-pipe. This cheap mod increases torque and like downpipes sounds great through the exhausts. X-pipes is mfg. by APR. Additionally, a word about maintenance CHANGE YOUR OIL and FILTER every 3000-5000 miles and watch for oil losses and replace ASAP. IMO Audi would love to sell you a new car after yours expires after doing 10,000 mi. oil changes on your old car. They don't want your car to last to 300,000 mi. If you do frequent oil changes, you don't need to worry about the OIL SCREEN ISSUE. If the history of your car is unknown, make a judgement call, which should not include prophylactically changing your TURBO'S. Remember, increasing power is more about making several changes that produce a synergism of effects. Stage I II and III is only one way to go about it. The warranty extension on the turbo's to 120,000 miles and 10 years is correct. I received the letter in the mail from Audi the other day. Check with your dealer for details because I believe this is not an open ended deal. It probably does not include all causes of turbo failure.@@savagepandaprojects
I got an a4 b5 and am looking at doing a swap. Im not sure as of yet if i should go 4.0 or 4.2 yet. I have the 1.8t (ATW) 5 speed quattro as of right now. Im gonna ride that engine till it dies, but want to start prepping the new setup
The problem with the turbos is found in models prior to 2016, that is, those from 2012-2015 that come with 420hp. In 2016 with the 450hp version Audi already fixed it.
They revised the oil screens for the mid-2017 model year. Still nowhere near good. Issues are still present with the oil screen clogging and pcv getting stuck open. Just swap to RS7, TS1, or SRM +4mm and throw out the oil screen and replace the pcv while you're already that deep. That's what I ended up doing. Ole 4.0 is still going strong.
@@nigels6786 Turbo oil screens are basically useless. If you have debris that big passing through into your turbos, you have more issues than just oil buildup😂. With that being said, I don't run my screen and I know plenty of others that don't run it either. Put 40k on my S7 since the screen delete/new turbos and it's had ZERO issues thus far.
Would suggest starting by contacting your local audi dealership for more details. I would think they would replace them proactively to prevent the car from being inoperable. Thanks
Hmm, why I don't plan on tuning. Just did Spark plugs, coil packs, oil change, DSG flush and Brake Flush. What I'm considering next, dealer said brakes are worn to 6mm. ($1,000). Removal of oil screen and PCV Replacement. Quoted ($3,000).
FCP Euro has a brake+rotor kit for the S6/7 for the front and back that cost $1200 USD. Zimmerman rotors and Forledo pads I think. They're pretty decent. If you want brake pads that make less brake dust, I'd look into the EBC Red Stuff pads on FCP Euros sight as well. I'm switching to those pads in a month or so, but from what I've heard is they're pretty similar to oem for wear/durability.
