I'm trying to not be overly negative on this given my recent experience, but it's a matter of "when, not if" regarding the turbo failures. Audi won't do a full-blown recall unless they are forced to by the NHTSA. Audi/VW are $billions in the hole from the Dieselgate fiasco in Europe and having to fork over potentially $10k (obviously their cost is less) in parts and labor to fix every turbo'd vehicle would break them. I'd be (hypothetically) comfortable driving my car for another 50,000 miles given the recent turbo replacement, but these cars are just too expensive to maintain/fix out of warranty. The combined replacement costs of air suspension & turbos are almost more than the car is worth. I've enjoyed both of my Audis, except for the times they've been at the dealer for extended periods waiting for parts/diagnoses, but it's time to try something else (with a warranty).

***UPDATE***: So I pleaded my case and after following up with the dealer several times, Audi agreed to cover 50% parts/labor to replace the oil screen, check valve, and oil/air separator as preventative maintenance. They quoted me approx $950 plus tax out of pocket. This includes 8 hours of labor at $150/hr and parts of approx. $700 at dealer mark-up cost. Now my question is, what exact parts need to be replaced when doing this job?

Below are the parts the dealer is citing but according to the TSBs, there are numerous additional gaskets and fittings cited. For example, the intercooler gaskets are cited (079-129-717-K & J), do they really need to be replaced? Also, the throttle body gasket (079-145-818), 2 gasket recirculation valves (079-145-417-B) and a whole bunch of other o-rings and such.

Can someone please help with clarifying if the below parts are sufficient to replace the oil screen, check valve, and oil/air separator or if any other gaskets, valves, and such should also be replaced? Thank you so much.

079-103-175-C check valve
079-115-175-G oil screen (revised design)
079-103-542-E oil/air separator (revised design)
079-103-161-Q cover gasket

N-910-568-01 seal rings (x2)
N-904-095-01 hose clamps (x2)

Spoke to Delta Auto Protection and they told me for my 2013 Audi S6 $4,285 for 4yrs and up to 150,000miles and I made sure that they cover the turbos.

I would get the all gaskets replaced since their already in there. plus with that low price take advantage. I would but that's just me.

What was covered under their plan? That doesn't sound like an awful price at all after hearing numbers from other members. Did you deal with them directly?

If Audi didn't recall/cover the problematic 5-speed automatic transmission in the D2s, chances are very slim they'll step up to recall the turbos. With both (D2 transmission and D4 turbos) the end results seems to be the same, "it's not if, it's when" like you stated dwboston.

I love these Audi D-body models, and have been looking at D4 S8s with envy. My biggest concern, turbo failures, with buying used versions of these D4s is coming true. It will be interesting to see if the "turbo failure" becomes the D4's Achilles heel.

My old D2 analog girl still looks good and runs well.

Good luck.

So far there are 52 4.0T failures posted on the C7 4.0T Audi Az Poll. It is not just an issue with D4 platform. The Audi 4.0T failure is in all the VAG 4.0T applications of that engine: 2013-2017 Audi A8, S8, S6, S7, RS6, RS7, 2012-2018 Bentley Continental Series and Flying Spur equipped with V8 4.0T engine.

Yes. I don't have any special knowledge of running production changes they made, but that is how I read this TSB--especially when they are specific by VIN within MY2017.
