How many km's (just ballpark)can one expect out of the turbos assuming reasonable sport driving (no racing) and good maintenance? After a hard drive should you let the engine idle for a while before you shut it off or is this outdated now? I also understand that there were changes to the turbos in the 10/00 builds and newer which should improve reliability, is this correct? Thanks in advance.

I would think the turbos are quite durable, unless the car has been heavily modified (chipping) and driven harshly.

assuming you don't abuse it and maintain it properly. Using good oil like 0W40 helps. Even if the blades bend over time, it'll still work fine for everyday driving. There are alot of other things that will go first before the turbos. I mean when they "go".. it's not exactly an explosion under the hood... For some, minor chipping of the fins warrant replacement. There are more durable turbos you can replace with (K04) but at over 7-8k I think it's hardly worth it. And yes, it is a good idea to idle for a few minutes after spirited drives, but it's actually better to drive for a few minutes in low RPM instead.. more oil gets to the turbos so they cool faster. Don't let the nuts on the S4 board scare you. They (I) are just **** freaks about our cars and for 99% of S4 owners, they will not notice any change in turbo performance in stock mode. I've heard of even chipped S4 owners having no problems with their turbos after even 100k kms. If you're not racing, don't worry about it. And if you are, you can probably afford it.. Racing involves chips, new DV's, TBB's, tires, wheels, exhaust....etc etc etc.
The S4 is the most versatile performance sedan available in Canada. The best all-weather car you can buy as far as i'm concerned. It is a wise choice.

I don't go above 3500 rpms before the oil is warm and I usually take if easy for the last couple of kilometers before I shut off the car. I'm not a huge fan of just letting the car sit and idle after a spirited drive because all you are doing is heat soaking all the components under the hood since there is no airflow other than the tiny electric fan. I prefer to just drive around slowly for a bit until the oil cools.

Similar to tires, if you drive like a nut, things will wear out and break. If you drive normally, you shouldn't have a problem.
