Access to radiators

[mikerd4]

Does anyone know if there is a guide for getting access to the aux radiators on the S4?

I hit a kerb yesterday and it seems to have done some damage, as all my coolant has decided to leak out. I slid very slowly on ice and checked the car afterwards and there are a few scratches under the bumper but nothing major. Im assuming the bumper flexed and hit one of the rads or hopefully knocked a hose off but I wont know till I can get access so can anyone help?
