Here is some hope for People with original KO3's and high miles.
Here are the pix of my two turbos. They are not the best pix b/c I didn't realize they were a little blurry I can take more if someone was interested.
Info:
2000 A6 2.7 6mt
122,000
original turbos
Apr chip for about 80,000
1/4 tracked about 15+ times
The fins show no marks at all. I think they look pretty good.
Turbo 1

How much of the story does fin condition really tell you? ...
Obviously, FOD can cause even brand new turbos to go.
But outside of FOD issues, I thought it was bearing issues that caused turbos to die untimely deaths. I assume one cause of bearing issues is unbalanced impellers that, presumably become unbalanced due to uneven fin wear (what would cause this?).
But I thought the vast majority of failures, especially in later models, was bearing failure due to oil starvation, presumably something fin damage tells you nothing about. Am I wrong in this?
