Ive noticed recently my B6 A4 Quattys been feeling bit rattley lately, just not as smooth as it used to be suspension wise. I had it in for an MOT last week and it passed no problems but the mechainc said that the anti roll-bar busing/bolt was loose and would need replacing. Anyone know if this would be the cause of what Im feeling in the car? Its just when Im driving on straight roads with any kind of rough surface, feels kind of rough and bumpy. Any ideas?
