Unless the central body cell is buckled (it almost certainly isn't, from the pics), considering how new the car is, there's no way it'll be a write-off, you'd be looking at about £20k of damage to write off. I'd say you've got a max of £4k damage there.
I had my 2 week old Golf MK5 GT Sport TDI170 (with 412 miles on the clock) clipped hard by a bus back in 2007. The car was about 12 foot from where i'd parked it to collect a take-away, and the bus driver didn't stop - a passer-by took the bus' details. The point of impact was on the rear driver's side wheel, and the car was pushed into the car in front. Damage was front bumper, rear bumper, 2 new wheels, 2 new tyres, a new rear quarter panel, new front grille, new bonnet, new radiator, 1 new wing. It was a £20k car with £8k damage, still nowhere near being a write off The repair was *****, lots of remedial works - i hated that car until I got shot of it, and the repairer was an approved VW/Audi repairer.
Approved repairer is not a guarantee of a job well done. Go to a place with a good reputation, you may have to pay a bigger excess to take the car to a place that isn't approved by your insurer as it is presumably your fault in blame terms.
...hope everything goes seamlessly. Looks like a new LED light is required, as the lens is broken
