Rich:
I've rebuilt several dozen turbos, including the k24.  As a rule, turbos on 
audis last about 150k, before they go out of spec (usually on the radial play 
test = bearings).  Your 2 standard deviations from the mean so noted.  K24's 
are notorious for failing mucho sooner, especially if they have been whacked 
at levels consistently above 2.2barPR, or have had BV failures.  Since I know 
Ingo's car quite well, and he has had both of the above 'problems', there is 
no doubt in my mind that he most likely has a turbo failure problem.

IME, the beefy kkk units outlast most of the other brands by a factor of at 
least 2, but all superturbochargers will fail, kinda like a computer hard 
drive, it's not an 'if' question.
