I think I'm going to have to recalibrate my ownership timeframe. I bought my S8+ with the expectation that I would own it for ten years, but I'm now thinking maybe seven is a better number (I live in a CARB state). But even an extended warranty doesn't eradicate the lack of a "limp home" ability if a turbo goes.
Least anyone think "dude buys a 600 hp car, and now he's jumping off the bandwagon", I was never on the bandwagon. I have previously posted that if I had been paying attention to Audi's plans, I would have ordered a SWB version with the 4.2 NA engine and the Audi Exclusive interior.
I'll say this about the 4.0 engine; it's power and smoothness is unbelievable. But to get there, some risks are introduced. To quote Murphy's Law, "if it can go wrong, it will go wrong". Turbos in a "hot vee" configuration operate in a hostile environment where longevity has to be a concern. Throw in COD
and Start/stop systems, and there is more mechanical stuff that can fail. But these cars are getting heavier, and there are CAFE standards to be met, so you have to,do what you have to do.
Im a frequent oil change guy, so I'll pay particular attention to the correlation of maintenance and turbo longevity, and hope for the best. Mike

Sorry, l didn’t mean to connect S/S to the turbo issue. Nor COD. The jist of my comments was that it requires more elaborate , mechanically complex, approaches to achieve gas mileage targets, and we owners can expect to pay for repairs.
The S8 doesn’t even have S/S, I’m pleased to say. Mike

A good number of folks have done that and checked for shaft play and had little / none. They are running with new oil parts and so far so good.
A few folks have replaced those faulty parts under TSB and have had turbo failure shortly after, due to the damage already being done. It's kind of a gamble.
If your car is lower mileage and little / no shaft play I would cough up the $2K in labor / parts to do the screen and valve. And hope for the best.
If your car is higher mileage, or you see shaft play... I would go in and do the above and think about replacing turbos. This also has to do with how long you plan to keep the car.
I don't want to tell folks to give up on the platform, nor do I recommend playing Russian roulette with a $10K + repair bill...
Fortunately I have another toy in the stable and honestly my tuned A5 Cabriolet is tons of fun 30 weeks out of the year minus sitting in hot summer bumper to bumper traffic. So I traded in for a Q7...
There are options with 3rd party extended warranties, longer than factory warranties that cover emissions systems (you blow turbo and car is undriveable due to drivetrain - engine would be covered unless dealer pushes back enormously), and other routes. Some have said screw it and go in and then go to bigger turbos with a respective tune... The biggest issue with this known problem is it has literally no warning signs...

And no, just replacing the turbos is not the answer. It's parts in the turbo oil feed design that are ultimately faulty...

My 2013 S6 has 99,963 miles on it and just had the 100,000-mile service done. I've been calling 3rd party warranties to get a quote but since I live in CA, there's not a lot of companies that will provide and after reading the forms. I'm kinda getting scared. I'm just trying to find a solution to this. Also with all these blown Turbos, I'm surprised Audi still hasn't called for a major recall. I honestly would rather replace the Oil Screen with the new design, Check value, and Oil Separator and upgrade the turbos for 2-3k.
