Rumbling Through Floor

Aldor27 · 11-08-2020, 07:54 PM

I’m having issues with my 2016 rwd 340i. Whenever I turn left going above 15mph ish, the car makes a rumbling noise/vibration. This rumble/vibration also happens when I turn the car on/off. We check the motor mounts and they seem good. Any ideas or suggestions? Nothing seems loose.

Mine does that on occasion but only if I'm low on fuel or my oil is low. Will have light vibration/ rumble at low speeds low rpm light throttle.

Only other time is when I'm driving on the freeway sometimes going 60 mph in a high gear light throttle to only keep speed, but that sounds like a quiet drone from catless downpipe with light vibration.
