It could also be your flywheel is broken. I had that problem and everytime I let off the throttle, it would kick back fairly hard. I pulled my engine and found out that my flywheel was broken(the dual mass setup springs will become too weak) and now with the fidanza no issues. But I doubt that is your problem, just a possiblity.

 

Check for codes again, since last time the problem wasn't occurring

 

If anyone has a dv please let me know. Also with the broken flywheel in mind, my clutch is kinda rough on me. Meaning i need a bit of gas to take off. Could be the way audis are cause this is my first one , also my first AWD car.Its very easy for my car to stall specialy if im reversing.Any ideas?? Or is this normal. Not that im complaing just maybe there is something wrong??

 

I havent got any mods . 5-7psi of pure stock power [&o]. Thought id fix all this lil promblems before spending any money under the hood.

 

Changed my DV to a 710P from a 03 A4 . Goes smooth as There was a lil crack on my vaccum nipple in the old DV. Im going down to the drags on the 27th so il keep you guys updated on my times. Anyone think i can pull off low 15's???
