no worries
i bought mine from ebay, and it originally came out of s Skoda Octavia, so when searching, try "Audi Changer, Vw Changer, Skoda Changer, SEAT........"
also bear in mind that although the in-dash multi changers from other makes within the VAG range, you might have to buy a different type of lead from the
dealers 
there's 2 types IIRC, 1 is about £15, the other is about £20
the one i needed was the more expensive

, so its likely you'll need the same
hope this helps
