S4 B8 engine whine

Post by dwlon » Tue Aug 14, 2018 1:31 pm

Just drove my S4 Avant B8 (2011/manual) back from a 3000 mile trip across Europe with the engine making a disturbing mechanical whine, especially between 50 and 70 mph or after fast acceleration.
There was always a mild whine at high speed which I assumed was just the supercharger, but it is now really loud. Anyone had this experience? What else could it be? All suggestions gratefully received!

Does the whine correlate to engine speed or road speed?

Correlation with wife-in-car?
Current 2015 RS5 Cab (Panther, most of the toys - except straigtheners), 2012 Discovery 4 family wagon.
Gone 2014 Golf R (Loaded, total sh!te), 2015 Cayman GTS, PDK and stuff, 2014 RS4, Sepang with most of the toys, SQ5, S4 lots of other cars - nothing of interest to be honest.

Try Audizine mate, they have a pretty busy B8 forum.
