I'm in need of desperate help please! I need to know what size my discs are on the rear of my Octy VRS 07 plate ( tdi )

Are they;

1.) 272mm diameter (models with bosch callipers)

2.) 286mm diameter (models with TRW callipers)

I have measured best I can and believe it's 272mm but there isn't a lot in it and as for calliper makes I cannot see any names.

Cheers.

I thought it was 286 on pre fl vrs. When I upgraded my disks, carriers and calipers using a 2006 vrs set up on my pre FL they were 286.

You should be able to work out the disc size by checking the PR option codes on the sticker in the boot - see the brake PDF in my post here for more info:
