I've not long puchased an Audi A3 and very pleased so far, however I'm after a bit of advice. I've got a 59 plate A3 Technik Sportback version and it has the chrome roof bars/strips. Would these ever of been a factory fit option or always a retro fit? I've had some damage done to one of them and taken it to a local VW dealer bodyshop as they are closer who after putting the VIN number can't find them and say they've never seen them before. They say they will speak with Audi, however I thought I would ask the question to see if anyone knows what the part number would be and if they are an Audi item or after market.
