The car vibrates a little when in idle :/

Hello guys I have a 2004 BMW 325i and I recently noticed that it has a small vibration when I'm at a red light and what not so I was wondering if you guys knew why that could be. Also, the engine makes a slight noise similar to that of a cracking noise

I was doing some research and I found that people who experienced the same things were saying that it was the venous. Do you guys have any idea or input for the rattling noise?

Vanos rattle sounds like marbles in a tin can, if your car vibrates at idle and smoothes out under acceleration then its your engine/trans mounts. The noise you hear is probably from the broken mounts, or if your really unlucky its both your vanos and mounts.
