Big "thump" experienced on even slight and easy acceleration after slowing down. It is not there if you come to a complete halt.
Despite the recall on the fuel gauge, I still experienced running out of gas with my "miles to empty" at 180, the second time at 80.
Rattling sound somewhere from the rear driver's side seat.
Low air dam, it caught even the lowest parking lot cement blocks.
Awesome car in the rain or snow.
Poor acceleration.
I own an Audi A6 2.0 Avant with manual gearshift. It too has a huge thumping when taking up the drive, this is the engine slamming the gears into place, i.e. loose gearing. I had this same problem with my previous Audi 80, so it does seem that this is a "feature" of Audi in general! What luck!
Actually this is a common problem with many, many manual vehicles (the thumping on shift). I had owned a porsche that did the same thing; and a friend that owned a new style gto had the same issue also. It is the gear doors slamming open and shutting.. it is very normal, scared the crap out of me when it happening on an awkward shift. don't be alarmed.
