Turn the wheels to the right

Using a T20 Torx bit, unscrew and remove the 2 screws (marked by the 2 red circles) in the left wheel arch

Turn the wheels to the left

Do the same with the two screws on the right wheel arch

Under the car, still using the Torx T20 bit, unscrew the 3 screws under the bumper (one is marked in the yellow circle)

With the 8mm key, unscrew the 4 screws (marked in the green circles). Leave the two at the ends at the end of the stroke to hold the bumper, finish later by hand

On the wheel side, raise the bumper (in the direction of the red arrow), and pull gently

If it doesn't come, use a small flat screwdriver and unhook the clips (there are 3 marked with blue arrows

Remove the last 2 screws left pending at the end of step 1

Gently place the bumper on the ground

Unclip the temperature probe cable (marked in the red circle)

Unclip the 2 fog light cables (yellow circle)

Put the bumper aside

Using the 8mm wrench, unscrew the 3 screws holding the optics (marked in red)

Disconnect the cable by lifting the clip in the direction of the blue arrow. Use a small flathead screwdriver if necessary

Put the optic aside and do the same for the other one.

Unclip the plastic protections (marked in the orange circle) and put them aside

Unclip the temperature probe cable holder (blue circle)

Using the E12 Torx key, unscrew the bumper reinforcement retaining bolts. Hold the nut underneath with a 13mm key.

Remove the bumper reinforcement

Position the new reinforcement in the same direction (there is a key on the left end)

Using the E12 Torx key and the 13mm wrench, tighten the two bolts

Replace the plastic protections

Replace the temperature probe cable holder in the provided hole

Reconnect the connections of the light optics (there is a foolproofing device marked here with a yellow arrow)

Engage the connections opposite each other, and push the red clip to assemble the 2 parts

Reposition the optics and tighten the 3 retaining screws with the 8mm key. Do the same for the second

Move the bumper closer to its location

Reconnect the fog light connections

Reconnect the temperature probe connection (orange circle)

Replace the bumper in its location

Approach the 4 screws from above and tighten them by hand

Reclip the bumper at the wheel arches and tighten the 2 screws with the T20 Torx bit

Screw the 3 screws under the car with the Torx T20 bit

Using the 10mm wrench, finish tightening the 4 screws on top
