so, I bought a 2007 A6 Avant 3.2 about 4 weeks ago. (my first Audi)
I have a couple of questions. since I bought the car 4 weeks ago, the speakers emit a hiss/growl upon starting the car and turning it off (I've narrowed that down to a failing/failed sub-woofer). but most concerning, is a developed light oil leak (which i'd like to attribute to some truck rubber I took hard to my undercarriage last week on the freeway). anyone have seasoned advice for me as to how to handle those issues as economically as possible?
Thanks in advance.
much love, folks.
