yes its changable.
About 5/6 torx screw's. 2 by arch, 3 under neath.
Its best to use a big screwdriver, and wrap a cloth around it and cellotape it so u dont mark your bumper.
Just try wedge the old 1 out. can be a little ****. I did it by using my hands aswel and using a 2nd screw driver to prob the retaining part down.
Will take no longer than half an hour.
Hope that helps
