My 2000 S4 has over 120K miles on the original turbos and is still running strong. This includes several track days and many autocrosses. With proper warm up, cool down, and maintenance, it is certainly possible to get a lot of trouble free miles out of the K03 turbos, I think they get a bad rap partly because so many of them are overstressed by mods and people who don't understand how to take care of them. I kind of wish I'd blow a turbo, because it would give me an excuse to build a monster.
