Ok, here is my situation.
My wife wanted an Audi A4 so I was looking on eBay and put an impulse bid on a 2007 Audi A4 FWD and damn it I won. So the car was shipped to me and right off the bat I thought it drove like crap. I called the seller and he said it was the turbo making the noise and causing the stuttering on taking off. Then the second day I had it the check engine light came on. I took it to the local dealer and the crankshaft vent value was bad. After having that replaced it drives a lot better(doesn't stutter) but still makes a rumbling noise when accelerating from a stop. It doesn't seem to make this noise when I'm accelerating while already moving.
Does this sound normal?
Thanks for the help.

 

not a normal sound....sounds like somehting is grinding or like a vibration?

 

Can you record the sound and post it up?
