2006 Audi A4 quattro 2.0

When i'm driving my car between 25-45 mph my RPM's bounce between 1800-2000. You can deff feel the jerk when im driving and its agervating as hell. If i take it above 65mph the jerking is gone and the rpm's hold. This is only when the engine is cold. Once the engine warms up the rmp's are fine when i'm driving. Please help. I was thinking possibly a EGR but i dont know for sure.

 

mine is doing the exact same thing! i've noticed that when i turn the car off and have the door or window open i can hear my exhaust sputtering down awkwardly too... I have an 06 2.0 also... if anyone has any information it would be much appreciated!

 

I was having a rough idle issue also so I changed my spark plugs and changed my PCV valve and the car is idling better. Sometimes she still feels like she is going to stall when I stop. I didnt replace the two vacume lines attached to the PCV but i checked them for cracks and they seemed fine. The car still jumps RPM's. Im fresh out of ideas. No check engine light but im gonna see if she is throwing any codes next week. There doesnt seem to be a power loss or a turbo lag when i get on it. Hopefully someone will have an idea .

 

check out bsh pcv revamp for the B7 2.0. smoothed my rough idle right out.

 

Toasted you are the man. It totally fixed my problem with the surging idles. It also smoothed my rough idle out also. I really apperciate it brother.

 

Lol. Glad it helped. It was the first thing I did the week I got the car. Awesome huh?

 

Damn I gotta get that BSH kit. Maybe Santa will bring it for me??

 

I'm having the same issue now. 2007 a4 2.0t with 83k. Same exact issue but its never at idle. I heard torque converters can be the culprit. I don't want to buy anything I don't have to. Anyone find any permanent fixes?
