My dad's SEL has body colour trim there. I think the grey is linked to the Scoutline version which was announced in May.

The first item isn't a fault as such. VW groups cars only zero after being off for two hours.

It looks like an issue with the pad not making full contact with the disk. I'd imagine your dealer will just replace the pad. The issue could be a manufacturing fault with the pad itself or some small pieces of grit have gotten trapped.
