I have some genuine Audi roof bars that I bought direct from Audi for my 09 plate S-Line Avant. What I am trying to find out is are these Audi's own bars or are they another manufacturers but rebranded i.e. Thule, Mont Blanc etc?Mine are the same as these -http://www.ebay.co.uk/itm/231281797411?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
