So you think just attach back at the top with a cable tie? for now
If your not sure I'll go and climb under mine and get a pic,I know it as I replaced my rear tieslooks like a anti roll bar drop link to me mate, might be wrong... odd place for one lol? im new to s3's so not familiar yet
Nothing to do with ARB its the link for the xenons, the link joints normally sieze and eventually snap the arm from the sensor that looks somewhat like the item i linked to
