I have only had my 2004 S4 (i.e. the 4.2 V8) a few days and I have only just
noticed a fairly high pitched whine noise coming from the engine. (Its not
the transmission - it does it in neutral) The whine changes pitch and
follows the engine rpm and its most noticeable around 2500 rpm. At higher
revs (maybe 4000+) I can't really hear it underneath the classic V8
Does your 2004 S4 make this whining noise?
Is it anything I should be concerned about? The engine seems full of power
and perfectly smooth. In fact it seems normal in all respects, apart from
this (slightly) strange whining noise. Perhaps its normal? Or should I get
it checked out before its too late?
