Working PDC

There are four parking distance control sensors on the front and rear of the E65 that send signals to the parking distance control unit. These sensors can go bad over time. While they are certainly not cheap, they are easy to replace. The sensors are specific to the front and rear and are color matched to the vehicle's trim color so make sure you know the color description of your vehicle before ordering. The sensors are usually non returnable so make sure you order the right color for your car.

The procedures are the same for both the front and rear sensors.

There are two sensors for each corner of the vehicle (red arrows).

User a plastic trim removal tool.
Figure 2

User a plastic trim removal tool. Starting in the middle of the bumper gently pry out the plastic trim piece from the bumper (red arrow).

Use your hands and the trim removal tool to release the trim piece by working your way around to the corner.

With the trim piece removed from the bumper the sensors will still be attached to the wiring harness (red arrows).

The sensors connect to the wiring harness (red arrow) and to the bumper trim piece (yellow arrow).

When removing the sensor from the trim piece you want to work slowly so as to NOT break the tabs on the trim piece.
Figure 7

When removing the sensor from the trim piece you want to work slowly so as to NOT break the tabs on the trim piece. If you are working outside in the winter take the piece inside to warm it up, as this piece can get very brittle over time. You do not want to break the tabs. Using two small flathead screwdrivers gently pry outward on the clips that hold the sensor in place (yellow arrows). Then lift the sensor out (red arrow). If it is stuck make sure there is not road grime or dirt holding it in place. Installation is the reverse of removal.
