My car, within the past 2 months started doing the same thing. Whenever I accelerate between 1500-2000 rpm and with the accelerator 1/4-1/2 pressed, I really notice a jerking/shuttering. If I floor it, there is no hesitation. Only when the accelerator is pressed moderately.
I can rule out the coils as I had all of them replaced at the Audi Dealership not too long ago.
Did anyone figure out the root cause? How to remedy the issue?

Did u manage to fix the problem, just bought an a5 1.8t, your problem describes mine in 100%
man i have been researching this same issue for my 06 Audi A3. Everything is leading to either a Vaccum Leak or VVT-I Actuator. My local shop has no clue what is going on. Frustrating...
I have an 2010 Audi A4. I sent my car in for repairs as it had the same problem. The mechanics litterly rebuilt my entire engine. I got my car back with the same problem... my launch diagnostics picked up a cylinder misfire, although the fact that it goes away after a certain RPM takes the issue to the fuel side of the car. Understanding how fuel injectors work, they have different spray patterns at different RPM. Note: My car has brand new spark plugs. I changed the ignition coil and still the same. I sent my injectors in to be checked and they were all fine. As i read on the forum, this could be a torque issue on the drivetrain. A wobble in the driveshaft can cause this issue. I will update soon as my car is still at the mechanics (3 months later).

If all else fails. Change the drive shaft as it is a possible bad inner CV
Have you found the actual cause? I am having the same problem!!HELP!!!
HELP!!i am facing the same problem on my 2014 Audi A3 sedan!! I visited many forums all speculating on coil packs, CV Shafts, spark plugs, flywheel, clutch. May I know what was the solution for yours?

This issue appears to plague many models. Mine is a B9 with 20k miles and the issue started at 15k miles. Had my driveshaft replaced and still have the issue. Anyone here been able to resolve? My next move is to get coil packs and spark plugs swapped out.
I have a 2001 a6 c5 Quattro 4.2. I know this is not the place from my car but I am having the same issue. I have replaced struts, axles, driveshaft rebuilt and rebuilt transmission. I have rear diff/carrier mount bushings on the way. I suspect mine is in the rear differential now. The gears in there must be worn and at that RPM they are in a state of flux meaning that they don't have enough torque on them to keep them from vibrating around. If I step on the gas I can easily accelerate out of this hard shutter. ITS NOT SPARK OR COIL PACK RELATED!! it's mechanical. When I figure this out I will post my findings back here for all of you.
Fixed. So I took my Audi back to the trans shop that rebuilt my trans. Told them I still have a shudder. They drove and felt shudder. They replaced the torque converter, rebuild valve body and replaced what they call a PWM Pulse Width Modulator. I am not sure which one fixed the shudder but my shudder is gone and the car runs very smooth now!
