There is a drain hole in the R230 trunk under the gray air box. Make sure it's clear so water doesn't accumulate. Mine had a rubber flapper in it, while another car had a plug. Be sure water can flow. If the PSE has gotten wet, be sure to open the box it's in so it will dry. One of ours had a half inch of water in it even though the trunk had drained.

The gas lift struts Rudeney mentions are available on Amazon for around $45. They are easy to replace, only requiring a screwdriver and possibly pliers to snap the ends off/on the car ball ends. No need to take apart anything. I found it easiest to install the bottom first, then lift the trunk up until I could line up the top. One of the easier R230 fixes.
