[BiturboS4] Turbo whine

It's common that cold turbos whine and it doesn't have to mean that anything
is wrong. I don't know about KKK K03 in S4, but at least my old K26/27
hybrid (in urS4) makes almost horrible sound when it's really cold and still
it's in perfect condition. I think that k03 shouldn't be as noisy, but some
noise is acceptable. My A6 doesn't seem to make any turbo whine, but it's
got good oil and has only 16000 miles.

Btw. how often you guys change your oil and what oil you use? My opinion is
that forget long lifes and use some castrol etc. and change your oils in
every 5000-7000 miles.
