Do I need to remove the rear bumper?

[BigFas]

do you have a pic of an actual car of the piece you're trying to remove? If it's the piece I think it is, then no, but I want to make sure

I think that's the bit that holds the PDC sensors.

Yup, that's the part. Anyone know how to remove this?

Mitsu, I don't think you need to take the bumper off. I think it will unclip from behind and you should be able to get at it from under the car.

looks like it will be no. 6 on the picture that will hold it on no. 6 is a clip i think anyway ;)
