Someone please help...

I have the most annoying vibration going through my car. I have a 2012 Audi A4 Quattro. If i put the car in Neutral, or Park, it is perfect. But, if i have the car in Drive, and im stopped, with my foot on the brake, i have the most annoying vibration that i can feel on the pedal, through my seat, and the center console. For example, if i have a bottle of water in my cup holder, i can see the water vibrating.

This has happened since i had the car. Any help would be GREATLY appreciated!

Most cars will vibrate while in gear. The engine wants to move the car and you hold the brake to prevent that which causes the vibration. If the vibration is severe you could have some mounts starting to fail (engine/transmission). These mounts are designed to dampen the vibration. You can visually inspect them for damage.

I think that's normal behaviour while you put your Audi in gear I also feel some vibrations, they are not extra strong, but you could definitely feel it while I put D.
