How do you remove the bumper on a Renault Clio Mk3 in order to change the headlight bulb?

You need to remove;

Both front Arch liners - 3-5 Grommets not sure exactly how many there are and 2 Torx screws underneath holding them on. (Do this on both sides)

The 2 bolts and 2 clips you see when you open the bonnet (Where the bonnet catch is)

2 bolts underneath holding the under-tray on.

And finally look through the arch gap like where the bumper meets the wing there's 1 bolt on either side undo both of them and your done.

P.S There is nothing else holding it on, may seem like it, just keep wiggling it. this is because the bumper and wing slot together and REMEMBER to put some protection underneath you dont want it smashing off the ground

Hope this helps
