Turbocharger Replacement I 2013 Audi A8L 4.0 TFSI Quattro

[@danielcollins2617]

Hands down one of the best automotive videos I have ever seen. You cadence and diction are remarkable. I learned a lot in that short video. Thanks.

[@4rings072]

Wow, thank you for the very informative video. I've learned enough and feel comfortable to remove my oil screen and check valve soon! Please make more videos on this generation of A8Ls, you know so much it'll be a huge benefit for us people who are intimidated by these cars.

[@JoeD-jl1yq]

Really enjoyed the video. Your explanations taught me more about my turbo system than I expected. Thank you for posting.

[@mist9999]

Frank Underwood !!! is that you? :) Sir you are a fine gentleman , Thank you for the great video

I requested Audi to replace my screen with the newer version that is supposedly less restrictive and eliminates the common failure that has been happening. They explained it was integrated into the turbos and could not be done independently. It looks to me after watching this video that they were incorrect. Possibly Audi will not sell the screen as a stand alone. Seems odd as this is a design defect and I would have actually thought with the number of failures would have been considered a recall. My car has just under 100k miles…hoping the Turbos don’t fail, but was willing to preventively replace the screen if possible. Wondering now if I should consider deleting the screen altogether, although as one person explained in the posts, it’s there to screen oil above 4500rpm, because the engine bypasses the oil filter above 4500rpm. Another stated it is there to prevent pieces from a failed turbo from dropping into the engine and causing bearing failure. I guess if I lose a turbo(s) I could upgrade to larger turbos for a much lower cost than what Audi asked to replace them (approximately $9000 for both). Love my car, but despise ticking time bombs. Great video, very informative. Thanks for taking the time to post it.

JH Motorsports makes a filter relocation kit for the S7. They may for your vehicle as well.

[@nigels6786]

How are your turbos holding up? I'm at 91k miles and stage2 and I'm on edge I feel like it can be any day now lol

[@FirstVenturetx]

Thank you for an awesome review.

[@The_WK]

This was a fantastic video. I'll definitely be using it for future reference. I'm really curious to know how many miles the car has on it now and how that 1200 mile trip went.

[@airrifle5626]

Well explained. Well done👏👏

[@billykilbey4712]

How many miles have you put on the new turbo?

[@JP-ou3ht]

Excellent video, thank you! I understand that the role of the screen is to provide filtration of oil above 4,500rpm and high load as apparently engine bypasses oil filter beyond that point. Is that also your understanding and are the turbos at risk of getting debris at higher rpm/load?

[@nandor690]

Very nice video!!! Love the explanation you gave. How many miles do you have on the Chinese turbo now? Everything been smooth?

[@MC-kg8hm]

The impeller on the intake side looks quite damaged and chipped. What checks can you do to ensure that no fragments went into the engine? I ask because I have the same problem at the moment with my vehicle. Thank you

[@Erichhh]

4:00 The check valve is intended to speed up the "priming time" to get oil to the turbos during a cold start. It does this by inhibiting drainback out of the turbos after shutdown. The screen prevents debris from a turbo bearing failure from draining back into the oil gallery, where it would then go directly to the bearings on the next start. However - If that check valve sticks, it pretty much guarantees a turbo failure. What I would do with no check valve - do not rev the engine for 30 seconds after a cold start, to give time to re-prime the turbos before they achieve any significant RPM.

[@EthanL21800]

When and if these fail how hard is it to bypass or take the screen and check valve off yourself?

[@hagani18]

Very nice video! Can't wait on the post-trip review!! Also can you please post exact model of the mainland China turbos you've purchased? There are many of those on eBay but as I've heard some of them don't match with original Audi OEM turbos.

[@devellwilson7099]

No check valve very interesting. Most shops say to replace them.

[@95ninety]

Nice video. How's it running now?

[@fredwilliams7893]

Did you have to remove the front end of the car to do this job?

[@danmadden9917]

The theory sounds very sound would like to know how they worked out after after trip.

[@amxaus22]

switching from stock cast to billet didn't that impact the air flow rate and maybe ECU re-tune? i recall RS6 and RS7 oem turbos have billet impellers and they can pump more are compared to stock cast S6/S7 turbos

[@nigels6786]

Ikr. I jus asked a guy at my tuner shop and he told me the same thing

[@danmadden9917]

If I don't pull the screen out is there a detergent I can add to the oil that will keep it from plugging up?

[@jayo7555]

My Turbos just went out on a 2014 A8L. Was just about to send it in for service then it happened wtf. Is their really an extended warranty for these now ? I'm going with RS7 turbos if that isn't true. And looking at the hardware version, I don't think it's ever had the oil screen update

[@RICHIE_RICH89]

Takes those dam oil screens out that blow turbos non stop from getting clogged there is good aftermarket hoses that eliminate issues of failure from low or no oil flow .

[@Crysinator]

I'm currently thinking about buying a S8 with what seems to be a failed turbo. Do you think it's possible for fragments to damage the cylinders? Thank you.

[@ThompsonAutoTest]

Yes. The compressor wheels are made of Aluminum.

[@stephenduncan6091]

Do you have to change the oil when changing turbos?

[@rosegold-beats]

It would be a good thing to do

[@danmadden9917]

Is it a very hard job to pull the screen and valve out?

[@observer222]

There is a recall for this vehicle about the exact problem you had!

[@Thokid]

I have white smoke coming from the tailpipes what cause that

[@miketrell1853]

Hey do you have a shop if so where are you located i i have an 2014 s8 that needs the turbo looked at.

[@brianquach9382]

How's the quality on the turbos vs original? I know originals used cast wheel vs billet. Price difference vs. OEM is huge. I see some aftermarket ones for $1800 vs $700 for the ebay Chinese ones.

[@nigels6786]

I been lookin for someone to answer this question for min now. Did you find out anything about them?

[@Noskillz_]

Is this the same as the audi s6 c7 ?

[@markg1495]

Yes. Although a little beefier internally I think

[@QDTS1515]

Where is the engine coolant temp sensor at

[@lindenblvd25]

curious what was the miles on the A8 when this happened and does it still happen with the newer 4.0T engines? I know this was an early model first year i believe.

[@ThompsonAutoTest]

Over 100,000 miles. With the new turbochargers, it runs smooth.

[@jaymack9442]

Yes it still happens. Mine is in the shop now. Luckily Audi is now accepting responsibility for a flawed design and are extending the warranty to 10 years 120,000 miles

[@Deny669]

Where ist the Position of the Öl Filter?

[@cantho11]

How often does turbos need to be replace? And how much it cost for labor?

[@billasingh5896]

I really want to know where is air intake temp sensor circuit 2 located if anyone know please comment

[@puprilla]

Man im having a horrible time trying to get a good price for someone to fix my audi. My epc light comes in for stuck runner valves and everyone is quoting me 4500+

[@jasonbooth6537]

How many hours did this take?

[@ThompsonAutoTest]

About 6 hours

[@blkmike123]

Where are you located?

[@ThompsonAutoTest]

Currently in Thailand.

[@DHRN-rq1qq]

How much?

[@ThompsonAutoTest]

About $400 for the pair.

[@run2jazz22]

I just got reimbursed $9,800 dollars from Audi on my Turbo Supercharger after it went out.

[@ThompsonAutoTest]

Good 👍🏼
