Are you getting any error codes? Is the check engine light on and/or blinking? The vibrating and other symptoms you described are common from shorted ignition coils. It also sounds like there's a separate issue with power steering - check your fluids, pump, and hoses.

2004 Audi s4. After a trip we noticed that the car had some vibration in the stick shift. The next day the engine was running rough(vibrating) upon start and driving it. I also noticed when you push out...

I was thinking a broken motor mount until you said the clutch stopped working. Tranmission / clutch is my only thought now - sorry.

Vibrates when take off

Hi, the vibration is due to the old transmission fluid in the car, the transmission will make the car to shake due to slippage (especially immediately after your car uplifts to a higher gear and is cruising at low rmps).
Get the flush and the problem will be solved.

Take care
