Removing and Inspecting the Oil Screen On My Blown Turbo 4.0tt S6. Oil Screen Replacement DIY Please like, comment and subscribe!!! Also follow me on Instagram @ S4vageperformance
JHM has their own turbo oil line kit that replaced the screen . It includes filters that are easily accessible when you remove the engine cover that you can clean with each oil change

hey man, do you have a link for one of those? thanks
Glad to see these types of videos. I’m stuck between choosing an S7 or RS7, but I’m looking into preventative maintenance before I pick one. Looking forward to see your progress.
@@datsuntoyy Well... I never bought either. LOL. But if I did, I think I would've chosen an S7. The ZF 8spd is great, but the DCT is noticeably better. A tune bridges the gap on power and aside from looks, I don't really feel like there's enough to warrant the extra expense of the RS. However, I didn't buy either one. I couldn't get past the lack of rear headroom (which I need for my FIL) and I simply cannot justify an engine-out service to replace timing chain guides/tensioners. I can forgive material failure, but I won't accept poor mechanical design that is borderline unserviceable. VW/Audi almost had me back...
@@VertigoGTI A few months back I hoped into my S6 and it started really rough. Like shake the fillings from your teeth rough. I thought I lost a Turbo and was actually excited as I was going to go stage 3+. Alas it was a stuck injector. Luckily, VERY luckily it freed up on it's own but the shop quoted me $12K to replace the injectors. Engine would have had to come out. Gotta love German cars. Side note, at 119k mile my DCT is starting to show it's age, I kinda wish I had an automatic.
@@datsuntoyy Oof, dodged a bullet on that one! I actually came across a 2014 S7 with a bad turbo and the price was really tempting, but the rear seat room wouldn't work for my wife's dad. If it was an S6 at that price... I would've happily bought it and sent it to an Audi specialist to get it sorted before I even took delivery. Even tho my original comment is over 2 years old, I still haven't bought anything yet. Between covid decapitating my old industry, finding my footing in a new career, and the insane rise in used market prices, I figured it'd be best to wait. I'm checking out other cars to see what'll work and oddly enough, the Jaguar XJ 5.0/XJR is the front runner. I would've never guessed a Jag would be on my list, but it barely feels like it's much heavier than my G35 sedan.
@@VertigoGTI I looked into a Jag when I bought my Audi. The rear seats are bucket style so baby car seats don't fit well, went with the Audi. I had the same problem when I drove the S7, that's why I got the 6. Consider the Genesis G70. Not quite the car the S6 is but more reliable and at nearly half the price. It's what I'd buy if I needed a new car right now.
Just had my 14 S6 done with the recall. Started doing the high whistle sound at idle which i knew immediately it was the pcv going out which was caused by the oil screen mentioned here. Audi covered it and did rhe oil change as well. $2790.00
I'm in the market for a '16 or '17 s6. Besides calling the dealership where the cars been serviced any way to inspect or tell if the screen is going to be problematic? I'll be looking at a 40 - 60k mileage car.
I’m currently in the market for one now too. I’d prefer an 18 at this point. Were you able to get into yours? 16 or 17?! Thoughts or answers to your original question from a year ago?!
Just a heads up to those watching, the cause of failure for the turbo failure is the cross shaped oil check valve that sits under the screen. The screen may clog and cause insufficient oil supply to the turbos but if the screen is clean than the cause of failure would be oil draining back into the engine due to a sticking or faulty one way check valve causing the turbos to be run on startup with no oil. The clogging screens was due to oil drying onto the screen if the vehicle sits for an extended period of time and is a secondary failure of the check valve failure. The part number for the oil check valve for most of these engines is VW 079 103 175 C
Hello Sergio .. was it in your experience or you found this information somewhere on Audi forums? I’ve read through a lengthy turbo failure threads on audiworld and audizine but don’t remember seeing anything about the valve you mention.
@@aspsp7186 This was my experience having to repair one and inspecting the failed parts as well as talking with a previous VW tech about the repair. The TSB 2044640 relating to the repair for the A8 also mentions to replace the oil strainer as well as the check valve several times and lists all the parts needed for the repair.
@@Sergio8191994 I had turbo failure due to oil consumption issue. They told me oil was getting into turbos. Replaced both turbos and all updated parts. 2014 S6. 64k
wow. thanks for this. so nice to see before tearing down. Have reassembled any further after this video? I'm doing the identical procedure; rs7 turbo chra's, pcv, updated oil screen, and possibly the check valve as well.
I change all to be safe. 2x coolant lines (each side of the top of the turbo) and oil feed in the center. Coolant lines use same o rings and oil feed use the same
I'm considering an M4, S5, or S6/7.., everything else in the German super saloon realm seems to have common issues I just don't want to deal with and the AMGs I want are out of my price range. I was really disappointed in the F10 M5s reliability. Would you say that the S7 has been fairly reliable? I've been looking at models below 60k miles.
WhiskeyActual yes the few issues they have aren’t really that bad if you’re aware of them and take preventive measures. Mine have all had over 100k on them and where very reliable. Imo one of the best bang for the buck german car in the segment.
I doubt it I think the issue is that the debris buildup on the screens and prevents adequate flow from going through. Unless there a way to backflush it from the turbo line
I did a Liqui Moly flush on mine at 80k. I changed the oil and put in the flush with NEW oil. idled 15 minutes occasionaly taking it to 2,000 for a few seconds then drained it again. The new oil was just as dark as the old. I put new and old oil in old spaghetti jars and put a flashlight behind them. Both completely blocked the light. To correlate with your question, If it can pull that much crud out of an engine, I'm sure it's doing something to clean that screen. I changed my oil every 7,500 average and still it was that dirty. I'm still running orginal turbos at 124k miles. I now do that same flush on all my cars and shoot for 40k miles.
. *Audi Recall July 2023* --- * --- This month end July 2023 I received a letter from Audi (as did all Audi owners of the A6 / S6 C7) that there is a vehicle recall action underway. I have to take mine in too. It transpires that these filters that have a wire mesh are too dense i.e. the wire mesh is too close or tight i.e the holes too small that can cause restricted oil flow to the turbos and damage them. They will be replaced by Audi at no cost (obviously) for filters with a wider mesh. ---- + ----
Probably not since it's under the top of the engine. Alot of mechanics charge like 10k to do this job. People say if u change the oil every 5k instead of 10k like it says. They don't have any issues.
This can be done without removing the front I’ve done it today left the oil screen out and flush regularly new seals are a must or you’ll do it all again RS6 2014 103k started spluttering at 4200 revs replaced cooler plugs and upgraded coil packs no cheap fix’s on these but worth every smile 👍🏼
your videos are great! I'm also working on an Audi S6. I got it to run but I'm having issues with it (rough idle). The codes read that the passenger side cylinders have random misfire... do you have any suggestions for me? The engine idles rough on a cold start for about 30 seconds but then runs smooth. Thanks!
Hi. How does a car behave without a filter? Everything is ok, did you have to install new ones? I have 86,000 MIL and I am thinking of replacing this filter. Greetings from Poland.
i’m looking at buying a 2013 c7 s7 with 64k miles. car feels great i ran codes on it and the only thing that came up was for a very small evap leak. are there any signs of a failing oil screen? and is there other things i should look for?
You won't know it's failing untill it's completely blocked. 64K you're probably going to need a front suspention rebuild soon. Mine was completely shot at 80 and should have been replaced much sooner. The front lower rearward arm bushing (a mouthfull) is best replaced with a polyurethane bushing. You're also looking at motormounts soon. I also had to do high pressure fuel pumps at 90k. Install drive train bushing inserts. Not necessary but makes it feel better.
