why is it common for K03 to blow? STFA but didnt really come up the the answer besides

So you don't think running outside it's efficiency range generating more heat than it should has
anything to do with failures? There seemed to be a lot more failures for chipped people than there are for stock. Granted, stock failures happened, but there does appear to be a statistical significance.

When a single Blade breaks off how is that by running the turbo out of it's efficiency range?
It's not, it's a manufacturing defect and in terms of some people that appear to have the retaining nut come off and shaft and blade go fubar, well hmm the nut backed off (again manufacturing defect). If there is a resonance issue when pushing the turbos a bit harder then that again is a manufacturing flaw.
Turbos generally go bad, oil seals and other if they fail, Audi failures are not indicitive of the normal turbo failures that you see on the market.
A turbo can only produce as much boost as it can produce and after that it's just producing heat.
having a stock car that had a bad passenger turbo, I'm a firm doubter that the chips are the culprits.
Having a few turbos cars before the Audi in which I ran MBC's and other such devices, without a single turbo failure (on smaller turbos then these running the same boost levels as chipped cars), I say no. I say it's AOA's way of covering for a poor design or trying to avoid high labor rates because they trusted Borg Warner to put out a quality product and they failed.
Remember this list is not indicitive of the market place and you would have to go out there to get real statistics, and I bet you would find many more "stock" cars with bad turbos. Hell I know of 3-4 allroads that went thru the turbo replacement ordeal..

If the turbo is designed for a specific range, then if it fails when run outside of that range
how does that become a manufacturing defect? That is like saying that because I bought a P4 2.0Ghz processor, since it is cut from the same wafer as a 2.6, it is a manufacturing defect and thus I am entitled to a replacement if I can't run it at 2.6GHz. Yes, stock people have had problems. Those should definitely be chalked up to manufacturing defects, but what percentage of those are even a turbo defect? Most of those ended up being overspool problems because of a ruptured TBB or oil starvation. K03's are small turbos. They have a specific range they are designed to run within. To say that chipped peoples failures are all because of manufacturing defects is naive to put it nicely. To say it is the number one reason is even tough to say. Go look at the polls from back in the day. A lot of people who blew turbos blew them because of ruptured TBB or other popped/ruptured hoses which in turn caused overspooling and finally failure. Chipping seems to have a similar effect (search on the X-Chip). Why would one chip have more failures per chipped car than others? Well it was running more boost than other chips. Hmmmm....nah it couldn't be the fact that it was pushing the turbos harder than all the others. Must have been a defect, right.

just finished with a k04 reinstall, put a newer oil return line. future k04 installers might want to
