I was changing a headlight lowbeam bulb and noticed that I don't have the "sealing cover" shown in the owner's manual. I've seen owners manuals show parts from other regions, so I'm wondering if these covers were on USDM P5s.
I have the sealing cover on my USDM P5. The dealer seems to be the only place besides a junkyard, if you are lucky enough to find a P5. I'm not sure if the sealing cover is the same as on the sedan.
I just had to go through this when my headlight socket melted everything together.
