AUDI A4 TDI (B6) 2001 im getting a humming noise only at around 15-20 mph,when slowing down,or at high speed at 80+mph. at high speed ive only noticed it on some bends,which noise will be present on a left hand bend only,and when slowing down or cornering to the left. I today jacked up the car cant hear anything when i spin the wheel by hand. Its coming from the rear wheel left side(same side where the coil spring is broken) Could it be cause of the broken spring? this has broke rite at the very bottom,and i also have a full tank of juice,could it be too much weight on the broken spring? or has the bearing given me some advance notice?
