Front PDC sensor replacement

I need to replace just one of the two PDC sensors situated either side of the front number plate on my X1 E84 M Sport. Can anyone tell me please, does this procedure require a full bumper removal including the snapping of the non reusable plastic wheel arch rivets, or can that particular sensor be accessed via another easier route?

Many thanks in advance
Oscar

Thanks, that is an excellent tutorial for full bumper removal but regrettably it doesn't answer my primary question about having to go through all of that process just to get to one of the central sensors.
Maybe through the upper or lower grills??

Anyone done this please?

I just checked underneath mine while replacing the foglights
And you might be able to get to it by removing the middle part or the driverside under tray, but the space is tight(crashbar sits right infront of the sensors).

Picture taken from Driverside. Yellow, green and brown wires that you see


Might be easier to just pull the front bumper...

All done. I confirm that it is possible to access all four of the front PDC sensors by removing the under trays.
5 x 10mm bolts under the bumper.
12 x 8mm bolts for the plastic under tray.
4 x 16mm bolts for the metal under tray.

Looks like something had hit the back of the sensor as part of it had sheered off revealing some of the wires.

nice, glad that you didn't have to remove the bumper to do the replacement.

Where and how much did you pick up a PDC sensor from? Do they come painted?
