question on 98 A4

["Ernest N. Lam" <nlam@CS.Stanford.EDU>]

Hello everybody,

I got my 98 A4 2.8Q with Tiptronic 4 weeks ago.  I would like to seek some
advice in regard to some of the problem I've experienced with my car.

When I almost get the car to a complete stop (about 5mph and 800rpm),
there is a driveline shudder (or engine vibration). The problem is
amplified with the A/C on.  Is there anyone else who experience the same
problem?  What could be wrong? 

Any comment/help would be highly appreciated!
