Firstly find a safe place your going to put the bumper when removed ie not just laid on the concrete and where your paints protected from scratches!!!!
Unbolt the rear lights, two bolts on left cluster and three on right cluster located within the boot and on the rear of the lights. Be careful when removing them as there's also a locating pin in the corner of the light nearest to the side of the car as shown by the red arw-full flex
This should reveal once removed the further bolts under the light on top of the bumper and also a black circle which is a retaining clip shown with a red arw-full flex. Push through the centre of the retaining clip but note where the pin falls as you'll re-use them. There's two bolts underneath the bumper also shown with a red arw-full flex.
You'll also need to release the wheel arch liner from the rear bumper which we found jacking up the rear of the car gave more space between the wheel and the arch to allow us to work without the need to remove a wheel.
Now its a matter of gently pulling the bumper away from the car and getting a second pair of hands to disconnect the rear plate bulbs as your sliding the bumper away.
This is what your left with. You will see the black plastic fitting rails/guides to the bumper/wheel arch edge which can be slightly adjusted if needed.
Re-fitting is obviously following this guide backwards!
Some technical data:
This is just a guide and if in any doubt consult a qualified bodyshop as I will take no responsibility for your decision to remove the bumper using this guide and then damaging something and trying to sue my ass lmao!
