No idea whether that's what it looks like, but it couldn't be the bolt that secures the steering to the rack could it? Comes to mind because it turned out that mine was missing and the mechanic asked if I had seen the bolt in the footwell (I hadn't). Really scary, I had taken it in due to play in the steering and it turns out I had done 5k miles with the steering just holding on the splines. Sent shivers down my spine when I thought of all the times I had driven down the motorway at high speed waggling the steering, thinking 'this can't be right'! Never mind the switchbacks in the Italian mountains! Anyway, hopefully somebody more knowledgeable will come along soon and confirm.
