Hi all I had a massive water leak when I got the car all sunroof drains blocked that are now clear however I opened the nav door in the boot to change a disc and noticed everything appeared to be covered in condensation is that normal? I didn’t see big drop as before

Of course this is not normal

Recommend remove all from the cubby
Dismantle each item as much as you dare, check for corrosion, on PCBs and connectors, and resolve (toothbrush / contact cleaner)
Commandeer the airing cupboard for a couple of days
Refit .

Ok and how to fix the actual condensation coming back? Current stable:

This could simply be a hangover from the deluge you had in there previously.

If it comes back, then you must be getting water in there still.... .

It's not normal but could also be moisture that's from your initial leak. Did you manage to completely dry it out? Test the boot seal too, they're known for going.

the seal going around the top? jug of water test? I don't know if its all gone guess it could be damp under the carpets have ordered some of those pots off amazon that take the water out the air will leave them in for a few weeks. Current stable:

Yep, the seal that goes right round the boot. Sit inside with the boot closed and have someone pour water/hose it and you will quickly know if there's a leak.

I've been looking a t a few l322s over the last few weeks and some of them are missing a bit of trim from the edges of the rear window, does this form part of a seal or is it just for show? First time FFRR owner

My brother and I had matching 3.6 Vogues from new but delivered two weeks apart. Mine had the trim on the window, his didn't! But there was no noticeable difference in boot sealing because of the omission and both cars performed perfectly over the next 12 years. I wouldn't worry about the absence of external trim.
