hello,

I just bought my 2004 audi a4 1.8t, and i realized while driving it home the car was shaking really hard on acceleration, and seemed to get worse the more i drove, so i took it to my company mechanic and he took it for a test drive and told me its not a big issue (im guessing he didnt feel the vibrations because it was sitting there for a while), and that it may just need a transmission fluid flush. so i went to an audi specialist and got a transmission fluid flush, which seemed to help the problem a bit. it doesnt seem to shake as often anymore, and the acceleration doesnt have a delay anymore, but every once in a while there is a minor shake at 30 km/h. i also noticed that if i give it harder gas on acceleration the vibrations dont occur.

please help, is this a serious issue, or just the cvt transmission at work? also what could it be?
