Pop the boot and leave the key inside when you shut it! Easy done...my mum did it on her Range Rover
Land Rover assistance had to come out, they earthed the car, somehow exposed some wires under the rear spoiler and put a live to one of then and pop went the boot! Was quite good to watch really!
I would try the AA or RAC, I know one of those companies has specialist VW units can't remember which though
