Yup, that's your 2nd to 3rd synchro ring gone.
Nothing you can do but replace it...and a gearbox re-build will probably cost you £200-300.
VAG 'boxes are bad for it...you just can't rush the gearchange or you clip the synchro and end up wrecking it.
Sadly, I've managed to wreck my 2nd to 3rd synchro ring on every VAG 'box I've ever had.
It'll not do any harm if you just slow the change down, and make a deliberate forwards, sidwards, forward motion rather than diagonally accross the gate.
