Well, not totally useless if I was into shooting wild fowl.

Can't complain about the replacement service though. Took the faulty item into the dealer's parts department at around 11am Wednesday, collected (and tested) a new one at around the same time today.

And it's been there for a while, too.

Just some rough calculations if it IS only the turbos that need doing -

£10,000 for the car
£2,500 for the engine remove/install
£2,500 for "new" turbos from eBay
£1,000 for various replacement bits and pieces that you end up fitting when removing/installing the engine as you always find lots of other things wrong the first time the engine comes out etc.

So "best case" it's £16k for a random person to fix this car, as long as nothing else major other than turbos that need replacing on a car thats been sat unused for over a year and with very high mileage vs that same person just spending £20,000 for a fully running car with 1/2 the mileage. For me, there just doesn't seem to be enough "value" in the car at £10k for a random person to see a benefit, unless you are a garage/mech who can do the engine drop/fit "labour cost free" to make it worth the effort vs cost of doing this.

What's odd this that the guy selling it would be the perfect person to actually do the work and then still be able to sell the car back up at nearly £20,000, making himself £5k+ profit plus his YT views over a multi-part video series where he does the work, which would be bringing in a little more money too. I guess he's too busy with his many other projects and just wants it gone.

Something still doesn't add up about that car.
Unfortunately I have some experience repairing turbos, and a few things stick in my mind.
Firstly, for all their temperatures and tolerances etc, turbos are very simple, robust and reliable in themselves.
When they go wrong, it's usually because something else has gone wrong, and there are lots and lots of possible causes, even more so with the RS6.
And when you have twin turbos, the chance of both of them developing an intrinsic fault at the same time is vanishing small.
Having said that, my car did need repairs to both turbos, but only because the engine cooling fan failed during an MoT and the tester didn't notice. The turbos are water-cooled and the engine overheated - so it was indeed a systematic external cause.
Again, there's clearly a problem with both turbos on Dean's car, but I'm not convinced that rebuilding or replacing both turbos will even fix the problem. Both turbos fail at exactly the same time? I'm sure it's something external, even though he's already gone to town on the crankcase ventilation system.
Even if the turbos are bad, I'm sure you could fit new CHRA's instead of the whole turbo.

As noted above, I had similar issues with my car, replaced the PCV and most of the non-return valves in the breathers, rebuilt the turbos myself - no change. Fitted new CHRAs last June, it still smokes from time to time but nothing like it did. While messing about with the car for this year's MoT I pulled off the intercooler hoses for a look-see. Drained a litre and a half in total out of them after 10 months use - considering that it used to collect similar amounts in a couple of weeks I see it as an improvement.
My next move is to replace the BMC air filters with OE and see if that makes any difference as they're in desperate need of cleaning and I've always had a suspicion that I over-oiled them last time I did it, which was around the time that my car started to exhibit problems although that might just be a coincidence.
