Hey there! Since i noticed this is the place to ask for help, i decided to give this a shot...
My 1996 328ic has got a whining sound inside the car, i am pretty sure this is not coming from the engine. It sounds just like if my stereo is badly grounded....but it does not come from my loudspeakers!!
I tried to follow the noise, and i am pretty sure it comes from the small speaker located under the dashbord just ontop of the drivers feet.....It sounds just like a bad ground, gets louder as i give more RPM.
Any ideas? I have asked for help here before, and i am very grateful that you guys take your time to help others, like myself.
Thanx in advance!
