Bodywork damage

I can't see anything in the photo that would cause a fail. Just to be 110% sure, perhaps a bit of duct tape (or something similar) over the hole in the bumper.

Its plastic so warm it up with a heat gun

I worked with a guy who had a Corsa B a few years ago. Never parted with a penny for anything in his life. One day driving home he was in front of me and I let a car out a side street which then drove behind him. Soon he pulled up at a stop junction and this driver ran straight into the back of his beloved Corsa, distorting the rear plastic bumper. She panicked and he initially thought it was me that hit him. Turned out she was not insured but some guy came round the garage the following day and paid out £300 for the damage. Now the guy I worked with tried to straighten out the plastic bumper but could not do it no matter what, however, eventually parking the car in the same parking place each day the sun as sure as eggs are eggs would come round each day and warm the bumper up, and then one day the bumper was so warm with the sun that the heat popped out the plastic bumper and straightened it perfectly. He only paid £20 for the car to start with, then got paid out £300 for an accident, and when he got rid of it received another £150 for it. Talk about having your bread buttered on both sides.
