Defo an engine swap / breaker now, but what are the odds of having two cylinders broken..... ???

I have seen the oil squirter break off and score the bore on a 32V. Not common though.
I'd see if you can borrow an endoscope if you can and have a look down the spark plug hole.
You can replace pistons without having to drop the whole engine but by the time you've pulled the sub-frame off to get to the sump, setup an alternative support for the engine, pulled the heads off (exhaust etc), it might be just as easy to pull the engine.
I'm very glad that I carried out a compression test on my S8 before parting with my cash
I feel for your mate although you did buy it knowing that it had engine problems.
I'm still interested in the LPG setup
