Try one of these part numbers for the actual Cover Caps, I think you may need the top number ?
16097230 80 (Cap Washer Jet Project) Animation series
Q97422 (Cap Washer Jet Project) Non animation series
These part numbers are for the fixings under the cap:
16097234 80 (Mount Hood Jet)
16097067 80 (Spring Washer Fix Cap Projection)

You may need to translate the page, I use Google Translate ?
There's two bumper packages on the Z, the standard and the "animation series".
You could also speak to Richard at Peugeot Group, go to the members list and find them there, just drop them a PM explaining your problem, and your chasis number.
Richard helped me out when I couldnt get a part number for a bit on my bumper, even my dealer couldnt find it, but Richard sorted it out. :thumbup:
