CPO just expired 12/21/18 - repair/advice please
 

Hi all,
First post here, anyone have an experience with the Audi Experience Advocate? CPO just expired on my 2013 Audi A4.. about three weeks ago. Of course I hear some humming coming from front right.. its a wheel bearing. Had it diagnosed at an independent cost to fix $500, over the phone audi dealer wants $120 (diagnose) + $600 for replacement. I called Audi Experience advocate and they won't consider a case unless I bring to the dealer pay the $120 for Diagnosis. Audi advocate of course won't guarantee anything so I am stuck.. I don't want to pay the $120 and then have them deny anyways. Anyone have any experience with something like this?
