hey so loving the a4 besides the problems it came with but iv run into somthing that isnt exactly a problem more of an annoyance my steering wheel is well "loose" as in to make a turn my steering wheel has done a full revolution "loose" a simple right turn or left and i have topped off the resivoir with prestone steering fluid but i know with audi`s theres a special mineral based fluid which i can order through the stealership because im thinking the fluid needs to be completly flushed then replaced with the proper fluid. Now hopefully its just this and not something else? anyone have the same problem out there any help is much appreciated
