>Hi Grant, JY and all,
>This has been an interesting and informative discussion.  From what I've read and heard on these list and AW forums, it seems like luck has more to do with the turbos failing than anything else.  Obviously chipping kills them a lot sooner, and people they have chipped their 2.7t should realize that, but even non-chipped car are not safe from it either.  Someone on this list 2 weeks ago (sorry I forgot who) had his turbos bit the dust at the tender age of 52k miles, and he supposedly followed all the usual procedures like proper warmup, cooldown and uses synthetic oil, and his car wasn't chipped.
>So we've established how and why the turbos fail (ok maybe not, it still seems more like a black art), my next question is how many owners are actually willing to shell out $7500 Cdn ($6000 USD) to replace those pesky K03s when they meet their maker?

Do the RS4's K04 turbos suffer a similar fate with similar regularity
or are they more bulletproof?

Maybe I could persuade the wife on account of it being more reliable..
