[325is1994]

i jus noticed this rumbling/rattling goin on under my feet, when im idling it feels like its going along with the idle, feels as if it might go away when i take off

when i was outside the car it seemed like it was coming from a little bit in front my rear driver side wheel

check the guibo, tell tale symptoms.... pelican parts for a DIY guide aka flex disk. you can easily see if it needs replacing by visual inspection.

check to see if the exaust system is probperly held on place.
check the screw on pipe connection for tighness.
then check the rubber donuts that go between the exaust and the cars body, they are called hanger, if they crack, brake, the exaust has no place of support so it will bang on what ever it gets closer too it.

also there is a matel support brakcet between the bottom of the transmission and the exaust. it is very common for shops to take the part out when doing service and not putting it back because they think is not necessary. but hey, germans are smart, if the part is there is for a reason. to give support for the exaust and to ensure it wont move in any direction while driving..

normally when somthing on the exaust gets loose it will vibrate together with the engine, since they are connected..
check that first.
if not, let me know.
