W123 Trunk Question

I pulled up the black plastic liner just to see what the metal was like on the passenger side. Lighting was poor so I couldn't see what was down there beneath the storage well on the passenger side. I felt what seemed like a drainage plug. Is there supposed to be a rubber plug of some kind down there?

It's a water drain. A rubber plug with small holes in it, it allows water out but not in (that's the theory, anyway). It often gets plugged up with dirt. Clean carefully, blow out w/compressed air.

I figured as much. I stuck a pen into the hole to see what would happen and I felt myself piercing rubber. But I guess that's what I was supposed to feel. I hope I didn't enlarge the holes too much with the tip of the pen.....

As Jeremy said, go in with some light and clean it out thoroughly. Then repeat on the other side. These cars rust easily enough, may as well not contribute to the problem.

You could install additional lights like my friend did to mine, and tapped the trunk switch for another switch so I can just open the main original light, or turn on both trunk corner lights for added illumination.

Very nice lighting. So is it possible to remove the black plastic lining on either side without damaging it for the purposes of cleaning? On an old BMW of mine, the equivalent part was extremely fragile and basically broke if you removed the whole piece.

Yes, the lining is pretty rugged stuff. As long as you use some basic common sense and patience you should be able to remove and reinstall it without issue. In fact, I'd recommend everyone do that periodically because that area behind the fenders is prone to collecting water and rusting. That's my problem now, the PO ignored some collecting water back there (due a leaking rear glass seal) and now I've got rusty wheel wells.

Mine has been neglected also and I am in the process of derustifyimg and repairing the rotted wells. The liners come out simply enough.

If you've taken out the fuse box cover on the W123 you'll realize it needs a specific way to get it out easily. The same goes with the plastic liners. Clean it inside out while you're at it, as well as remove the trunk floor board and carpet to clean it out since there's also another drain in the spare tire well you might want to clear up. All drains can be poked from outside but it's best to clean it from inside, of course.

Check that your fuel filler neck grommet is not leaking either. If it is, fuel can drip into the fender and make its way down the crease between the wheel arch and the quarter panel, into the drain area by the foot wells.

Finally, the rear quarter panel side trim mouldings have little red clips that hold them in, and also prevent water from getting in. Lose one of these and you're bound to get water in the drainage area again.

Just a heads up in case you see dampness collect there once more. Otherwise cleaning should be fairly straightforward.
