Withdrawal
Loosen mud flaps in right and left wheel arches. To do this, remove the spacer clips, having previously knocked out the pins in the center of the clips using a curved screwdriver with external slots 2.5-3.0 mm in size. If the spacer clips have caps, then first press the pins with a screwdriver, and then remove the clips. Finally, move the mud flaps away from the bumper.
Note: You don't need to remove the wheels to do this.
Open the luggage compartment, remove the rear trim, see p. 133.
Use a 13 mm wrench to remove 3 nuts -arrows- each from the bumper on the left and right.
On a vehicle equipped with a parking distance control system (PDC), loosen the cable tie, disconnect the plug connector and free the wires. Pull the bumper back a little and pull out the wire insert along with the wires.
Together with an assistant, move the bumper backwards.
Installation
If required, complete the bumper, see drawing W-48301.
If necessary, fit a plastic cap -3- onto the energy-absorbing buffer. When removed, the plug often remains in the energy-absorbing buffer receiver.
With the help of an assistant, insert the bumper into the side guides -1- and push it forward. Press the front part on the side and slide the bumper forward against the stop. In doing so, the front bumper guide must fit into holder -2-.
On vehicles with a PDC system, fit the wire insert together with the wires, connect the plug connector and secure the wires with a cable tie in the position that they occupied before removal.
Raise the rear bumper slightly, align it parallel to the body and tighten the mounting to 20 Nm. The distance between the bumper and the body must be 5±1 mm.
The height of the bumper is adjusted with the bumper removed by turning a plastic head with an internal hexagon located in energy-absorbing buffers.
Install rear luggage compartment trim.
Attach the rear mudguards, insert the spacer clips and drive in the spacer pins of the clips as far as they will go.
