I'm considering buying a used S4 in the next few months...

Thanks in advance.

Old badge = '00 or '01.
New badge = '01.5 or '02.

There must have been some significant mechanical changes...

I say looking for the f-hose as my 2001 (pre-2001.5) has the newer badges.

The turbos were revised slightly (larger oil inlets), the vaccuum system hoses were changed (no more F-hose, brake booster vaccuum connection to bottom of accordian pipe, the PCV valve/y-pipe connection is slightly different), the ECU went from 551H to 551M.

But if you are trying to tell an '01 from an '01.5 the easiest way is the badge.

Supposedly better oiling for the turbos. Can someone actually verify that???
Remolded intake manifold (slightly better efficiency)

The difference is not really that much better.

I believe the oiling problem was changed with the '01

SLPR S4

Agreed ... F-hose. I updated my 2000's badge set. ;o)
