Took my car to the car wash today, and the guy drying my car off pushed one of the PDC sensors in the rear into the bumper... would anyone be able to tell me how to remove the rear splash shield so I can get behind the bumper, or if there is an easier way for me to replace it, please let me know!

 

Whoa, he's pushing pretty hard then.

It'd be easier to remove the bumper. The rear splash guard is attached to the bottom of the bumper via screws and to the chassis (from the inside only accessible once the bumper is removed).

Here's the plastic with the bumper removed



The bumper comes off really easily once you remove the ~10 (or so) screws. They are obvious. Otherwise, check out Anzafin's post here:

Someone hit me the other day and did a runner. I managed to scuff out any marks but had to remove my rear bumper. Pretty simple once you have seen how.

Basically 4 bolts on each wheel arch running adjacent to te rear bumper, 4 push pins around the bottom connecting the bumper to the underbody plastic.( these would need to be replaced with new ones), 4 star screws in the boot/trunk (2 below each tail light)

Once all this is done, the bumper is clipped into the side. Definitely need two people to take it off so it doesn't scratch the floor. Nearly happened to me...

 

those sensors shouldnt just push in from drying the car.
