What's missing from this picture?
 

I'm working on my brakes tomorrow morning, so I've just been round the car loosening all the calliper bolts.

Inside the offside front wheel arch I've noticed that it looks like there's something missing...

(Right in the centre of the pic)

Any ideas what it might be?

Have you checked the other side?

Yeah. I don't see what it could be.

Mount for abs sensor...????
