Invisible line isn't
-
Steve, this is sort of an OpenGL problem. I don't think there is a solution for it unless you replace the material image with one of the whole center section and make it one hunk of geometry. It appears that we're seeing the edge of the material image. I wonder if it has to do with the unused white right half of your material. Why don't you crop the image down and get rid of the white on the right half?
-
This may have to do with me inspecting the model, opening components, and such, but I did find a hard edge right there where you pointed to. Of course, Dave's comment may be the ticket.

Well, I'm home now, and the model looks just fine on my desktop (the same model I copied to my laptop).
Now I'll copy the model from my laptop to my desktop and see what happens.
I really appreciate your comments and suggestions.
Why can't I ever have a normal problem?
-
Well, I copied the dang thing back to my desktop and of course it's fine now.
I don't understand, I copy models back and forth all the time and there's never been a problem. And if it got messed up somehow while being copied, why just the steering wheel horn? All of the other mirrored components (and there are a lot) look ok.
Wait, I just thought of the solution!!! I'm gonna take a hammer to my laptop! That'll be fun

You some times see lines like that where geometry in different groups/components meet. It's the calculations of the pixels that doesn't meet up 100%. I usually get around it by applying the front material to the back. It can appear as though occasionally there are leaks where you see into the back/inside of the mesh.

Ya beat me to the answer.
For some time now, I have set both front and back default faces to white. Orient faces does not always work properly.
And, more importantly, I set both front and back faces to the very same texture/color.
That eliminates any phantom lines, and if there is an unwanted internal face, it shows as a white line on the surface. -

It won't work properly if your mesh has edges that connected to more than two faces. Then it's impossible to determine orientation.
I'd still try to orient faces correctly because tools will some times require faces to be oriented properly - otherwise unpredictable results occur. -

Maybe their next update should include an implicit Orient Faces before getting down to business.
I keep forgetting.

I keep forgetting.Make your back face color really obnoxious and work in Monochrome face style. You won't forget.

While all this info is well and good, and much appreciated, the thing is, I've done hundreds of mirror reverse components (at least), all done exactly the same way, and this is the first time this problem has reared it's ugly head. If it was something I had tried for the first time or if I had done something even a little different, that might explain it. But by now doing this is second nature to me, so all of the possible explanations offered up simply (IMO) do not apply. There's nothing different about this simple and very basic model that should or could explain that accursed white line down the middle of the steering wheel horn.
But I've put this behind me, and until it happens again I'll just add it to the ever-increasing list of weird things that happen in SU that you just have to live with
