Gutted for you mate but look at the positive, there's no panel damage so when fixed will literally be as good as new.
I had an accident in mine and my insurance company tried sending it off 200 miles away to some generic garage I had never heard of, I refused and said I will take it to nobody but VW to be repaired, they protested for 24 hours and I had to speak to a supervisor at the insurance company who wanted to know why and then they accepted it and I dealt with it myself locally, it your right to get it repaired by who you want as long as the price is reasonable
Just thought I would put it out there
Alot of time when you drop you car off at VW dealership they move it off site to a manufacturer approved repairer.
Its your decision where it gets repaired it simply needs to be at agreed rates.
