and from the back there is this wheezing/buzzing sound , it sounds like it's coming from under the car, def not the engine I dont think, kinda near the back actually?
Fuel pump most likely.
Mine's right beneath the seam between the front and rear doors on the driver's side.
As far as I know, the sound is no indication of failure; I know that other people with E30s have this same thing going on, and haven't experienced any problems with fuel delivery.
