https://rimmerbros.com/Item--i-GRID001823 The RAVE manual says that there is one each side of the boot , consisting of a grille with a rubber flap to vent air from inside the car to the outside space under the bumper . Not sure if they are in the carpet side-liners or beneath them . If they have been sealed off then condensation will happen .

Many thanks for all of your suggestions. I have now played a hose directly on to all of the areas you have suggested. There was no ingress. Finally, I lifted the boot lid and played the hose under some pressure directly to the side valleys and top seal and let it run heavily into the rearlamp clusters. Nothing, no ingress. Is there a more demanding test I could try? Shall I spray form the underside?

Your splash test should have shown this up but there is a seam where the rear wing and the boot frame join along the side gutter's of the boot - it runs from up the C pillar to the top of the rear light aperture; the join in the area of the rear screen lower corners isn't always flush. If the sealant has failed here water gets into the cavity and runs down the seam line and then drips inside the boot just above the rear light bulb plattern - which is a bit misleading if your checking the rear light seals. There is another possibility of water getting behind the boot lid hinge plates via the two fixing bolts, carefully remove the bolts and give the threaded holes a dose of sealant (do the 4 bolt one at a time so the hinges don't move). |

If you remove both boot inside side coverings, there's a plastic ventilation vent either side, about 8 x 4 inches. To successfully reseal, you need to remove bumper, push flexible click tabs back through, then seal opening with silicone based sealant. Click vent back into place, also check masking type tape nearby , plus other mastic finishes in that area.

Just a thought as I'm currently chasing the source of a very leaky boot as well - are either of your rear lights cracked? I've just replaced one of mine that had a relatively minor crack and once it was off the car I filled it up from the inside using a tap and it was surprising how rapid the drip through the crack was.
I've also replaced the rear gaskets with a set of these, so next time it rains I should know if the rear lights were the main source: https://www.the75andztclub.co.uk/for...d.php?t=142690 |

With your help I've now found the internal drip point, but yet to find the source for the drip! It's dripping from the underside of the U channel half way between the LH rear lamp cluster and the LH bottom of the rear windscreen. (By U channel I mean as in the 3rd pic down in the very helpful Post #18) Water is trickling down on the underside to form a large drip, but I've yet to trace the ingress point. Further up the underside of the channel it goes into a void nearer to the rear screen. As with many of you, I've spent hours on this so far. Eventually I needed help with my Son directing the water jet and with me halfway into the boot with a torch.
