You're quite correct Spike - the plates for the front valance are available separately from Audi, but seemingly, they are included in Vagparts kit, along with the new light switch (which is about £60 on it's own!).
All in all, a very good price for the kit, even if wiring it in is a tricky job, as are most tasks requiring wiring to pass through the A2s bulkhead.
Cheers,
Mike
