Most of this thread is old - hope someone will respond! I know what the front radar module looks like and where to find it. It's easy to see the locations of the Parking Sensors on the front and rear bumpers. Are the Parking Sensors also used for the Blind Spot assist, or are the Blind Spot Sensors separate from the Parking Sensors, but also on the bumpers and hidden from view from the outside? I anticipate the Blind Spot Sensors are separate from the Parking Sensors.

The blind spot sensors are hidden beneath the bumper skin. They're about the size of a deck of cards and are located at roughly the corners of the rear bumper, about halfway up the bumper from the ground. On my bluetec each one can be fairly easily accessed by removing some bits from the bottom (muffler heat shield on one side, DEF tank splash guard on the other iirc). Same part number on each side, wire harness enters the sensor block from the end closest to the back of the car.
