Any suggestions, other than don't let it sit parked for so long?
Exact symptoms of FPR failure. Confirm with fuel pressure gauge left on a few hours. Should hold 10-15 psi overnight.

On the E53 usually this is just the tiny o-ring between FPR and filter had failed. I'd replace that before the whole assembly.

I sealed it up with new butyl when I replaced the cover a few months ago so I'm not sure why it's getting damp in there.
Most light housings have a vent. If not you did the right thing to make one taking out the lamps but you need to heat the assembly to get out the moisture you can use the likes of IR (Quartz) heater or even black garbage bag in direct sunlight you want to get it up to about 150 for 4-5 hours.

You can remove the whole unit and put in an oven that goes that low (like keep warm mode)

I have a spare from the old RH housing that I replaced after destroying the old one trying to get the clouded cover off; for some reason the LH housing had a butyl sealant that separated with heat, but the RH one had RTV sealing that absolutely would not let go. I found a replacement on the bay of E for cheap and it's fine.
If somebody glued with silicone you will have to cut if off. Permaseal from the factory will be butyl

Do yourself a favor and get a pair of hid 3400k from Amazon. I paid $40 for the highest rated pair I could find back in 2015 the first fix I did on my new to me 2001. If you are even noticing any color shift it's completely end of life and 30-60% loss of brightness.

Replace as a pair and put the brighter of the two into your spares bin.

The knock off Amazon pair I bought lasted longer than the e53.

My car has those shades and they seem to be made of dust and gossamer, any tricks to getting the panel off without damaging the shades? What adhesive would anyone recommend to glue the panel fastener blocks back to the panel? Most of those fell out when I removed the donor one. I'd imagine mine will do the same once I get around to doing that.
It takes about 90 minutes to rebuild a DLA. Find my awr-fix thread on the topic. Replace the brush end of the motors with a donor motor from Amazon.

JB Kwik might be best bet for the hidden fasteners; maybe take some old single use pins for alignment to get into position.

It's not difficult to remove the shades which must be removed before the door card. There's one screw and one hidden spring fastener. Find a YouTube video for the method.
