[Biturbos4] B5 S4 steering noise

[wilson]

Hello Ti,

You're not alone.  My car recently developed a similar sounding noise, but
less pronounced than yours.  As with your findings, power steering level is
OK, etc.

 If you think the sound is the steering rack, maybe check for the sound
from under the car next?
