I have for sale a pair of genuine AUDI roof bars in aluminium finish to fit an A4 Avant '02 on (B6) (Please be aware these WILL NOT FIT the earlier B5 Avant - I tried without success, hence the sale !) I bought these in error today and will happily swap for a genuine pair to fit my B5. These are the lockable (un-nickable) type, are in excellent condition and come complete with 'key' Cheers, Mark. PM for Pics....
