So iv been snooping around . I have concluded that the problem lies in my sway bar but i cant aaeem to find the model number for the sway bar for my Audi A5 3.0L tfsi 2013 . Iv read a couple of help full posts but havnt come accross one that has the model number on it . I want to pick up a pair online as my local dealer in doha is charging me around a 1000 dollars for the part and labour .
