Not your usual Coupe with water in the boot...

[Brouse]

Hello forumers,

I noticed my rear window starting to condensate recently, I figured my dehumidifing hacky sack thingamejig (actually works really well) needed 'recharging'. Having done that and the problem persisted, I turned to the forum so research possible causes.

General consensus was the vents are the culprit. Except on mine the vent and area below storage net is bone dry and no ingress from light cluster. All the turret foam and additional soft bits dry also as well as carpet behind drivers seat. Also thankfully battery box is bone dry also.

What I did find was a small trail of water, down the right hand side and lower edge of the battery box (as you look down on it from outside the boot), pics below. I've dried it out with rag and hair dryer and have left trim removed/drying.







Other things to note, my drive is on a slope and slightly to the right, rear end downwards but I do alternate, and the car can sit for a week or two sometimes.

Any ideas? Could it just be condensation? Could the battery box seal be leaky or allowing damp ingress? << Seems unlikely. Perhaps just monitor for now?

Any thoughts appreciated!

Are the bumpers that the boot sits on and that are located on left and right pillars still in place?

One of mine broke and as they act as a plug for the hole they screw into there was a path for the water that runs from the roof, into the left/right hand gutter and collects near the tailights to sip into the rear quarter panels and then boot. The water was getting in the car exactly above the right hand small stowage nets and collecting there before running down into the battery box.

Ah yes sorry checked those also as I thought I'd solved it and they were fine. I will will monitor those however.

Not familiar with the layout of the coupe, as we only have roadsters, but you could try looking behind the bumper. Last year I solved a leak on my son's E85 - after removing the bumper, there is a plastic section held on by screws; a half dozen or so (see pic). As I could find no other source I hoped that the leak was at one or more of those, so removed them and applied a small amount of silicone in the plugs before refitting. Over 12 months later and the boot has remained dry ever since, despite recent rain of biblical proportions!

oh nice, not sure I have that but will look
