Just had bearing done on front by an Audi maindealer mechanic, £120 for part, £80 fitting. Audi charge 2 and a half hours fitting at £136 an hour + part. Sounded like an aeroplane and now all is quiet again. Hub comes complete with bearing, ones advertized for peanuts on ebay are not complete and bearing only even though the pics show complete hub, or £95 from Eurocarparts complete, hope this info helps someone.
