I lease my 2006 (took delivery October 2005) and have had the same issues with my 2.0T Tiptronic. The engine idles very rough in neutral as well as in drive. When you sit in the vehicle and place your hands on the steering wheel you can visibly see your hands shake on the wheel. You can feel the vibration throughout the vehicle and is not a pleasure to drive. My vehicle was in the shop for three weeks being serviced. While in the shop had the pleasure of driving the dealer's 2008 2.0T Quattro, not a vibration to be had! Just picked up my vehicle today and still shakes like a disco!!! No FUN. Stay away from this model!!If anyone has had any luck getting rid of the vibration in this model, let me know so I can tell the dealer how to remedy it.

Mine isn't rough at idle in nuetral, just in gear.

So has anyone got rid of this rough idle? I still think it's ridiculous that Audi would sell a car that performs like this. Anyways, I still have it. After 1.5 years I'm hoping there was a solution.

2005.5 ticking yes, but no shaking with MT. Audi is replacing the ignition coil for free for our models. Have the dealer check and replace it. I hope it helps.

This problem is related to the tiptronic A4 2.0T.

I have a 2005.5 2.0T Tip and I have noticed that the engine runs a bit rougher in the lower RPM then my other 2 Audi's. They are both 2.8 12V V6. It acts like it will stall if you slow to a stop real fast, .2 sec later the idle will pick right up and be smooth. The engine sounds a bit rough at times but never vibrates. Very smooth about 2,000 rpms.

I get an average of 28 mpg on the computer and that is with APR 93 octane programming.

The engine is not as smooth as my 12 valves but makes 50% more power.

Sorry very smooth ABOVE 2,000 rpms

I had a 2006 leased for 2 yrs - the engine fairly rough at idle. I now have a 2008 on a three year lease and it is a bit better (both with the 2.0TQ with Tiptronic). The newer (2009 and later) 2.0T is much smoother - a few friends have them. IMHO part of the problem is that the Audi's have longitudinally (front to back) mounted engines. Most 4 cylinder cars have the engine mounted transversely. When the engine shakes at idle it is a side to side motion. The shaking resulting from the Audi’s layout is much more noticeable than a Toyota would be with the transverse mounting. Lift the hood on a silent, smooth idling Camry and the engine shakes, it simply isn't transmitted to the body as directly as it is in an Audi. It is easier for the torque-ing of the idling engine to shake a 72" wide car from side to side than it is to shake a 192" long car front to rear. Physics! My 2 cents
