Get the gearbox oil changed!
The ZF 6 speed in my old 3.0 Tdi quattro C6 was supposedly "lifetime oil fill" but it started giving some clunky changes north of 80K miles - check the C6 forum and you'll see various discussion. I paid for the local audi dealer to change the oil (not cheap as you note) and it sorted the issue. OK the ZF 8 is next generation and certainly a sweeter gear change than the ZF 6 but I suspect that much of that is down to electronics and some clever design, I doubt it changes the wear and tear or the fact that oil "ages".
To be fair "sealed for life" is probably true... when the gearbox throws a cog at 100K miles with the original oil then it was truly "sealed for life".
