steering column rattle/ weird shift
 

Ihave a 98 passat 1.8T.... when idle or at a stop the steering column vibrates pretty bad.. when u pull away it goes away, and also at a stop if u turn the wheel it will go away... no clue what that is... also when the car shifts into second it feels like the car decels then slowly acclerates again.. when passing 2nd on a downshift it kicks pretty hard.. no other gear does it do that... its a triptronic transmission if that helps... plz help
