981 Cayman Sodden/Wet Passenger Footwell - Page 1 - Boxster/Cayman - PistonHeads UK

I have a 2014 Cayman S owned from new with a full Porsche history. For the last two months I've noticed the interior has excessive amounts of condensation after its stood overnight. A look inside today revealed the passenger foot well carpet is soaking wet (and probably has been for a couple of months). Are there any known issues with water ingress on the 981? I had quick search here but couldn't find any relevant posts. Any guidance would be appreciated.

I'm not 100% sure where the drains are at the front, but if you lift the plastic cover to expose the battery etc, and look around the scuttle panel beneath the screen pillars, the are somewhere in that area think. You should really remove the passenger seat and lift the carpet, because some of the electrics are under the carpet and you can suffer major problems! Make sure you remove any excess water, and keep the carpet propped up and out of the way. We put a de-humidifier in mine, and incredibly it "sucked" out all the remaining water over about 3 or 4 days, remember to empty the container in the de-humidifier! HTH

HTH Yes the car lives outside... looks like its time to find the drains, unblock them and get a dehumidifier thanks for the advice

HTH Yes the car lives outside... looks like its time to find the drains, unblock them and get a dehumidifier thanks for the advice ....... make sure you take the seat out, and lift the carpet away from the electrics and remove anything that is removeable. Once water gets into the electrics you can end up with major problems costing £££££££'s. My Boxter now lives under a cover to stop leaves etc from going into the drains!

So I've had a quick look this morning, after lifting off the plastic panel I can see the drain pipes in the scuttle area... can anyone point me in the right direction with an image or link (i've searched the internet without success).

Have a look on Boxa.net on page 2 of the 981 section. There's definitely also been something somewhere on here about the problem but sorry haven't time to look at present.

Description of Boxster drain hole clearance on this Planet9 thread. Cayman fronts at least should be similar. https://www.planet-9.com/threads/981bs-water-leak-... Edited by Green1man on Thursday 9th January 16:20

Just had a rummage for my first aid kit which I keep under the passenger seat last night and found the carpet and the first aid kit sodden. Dammit! Glad I found this thread!

Update: After finding out where the drain holes are under the folding top hinges, I bought myself a long blow-gun (I already have an air compressor) and was able to get the nozzle to seat into the rubber drain holes and blow them clear of all kinds debris. We've had all kinds of torrential rain since but my car's interior has remained bone dry with no dampness at all inside. You certainly don't need the blow gun to be as long as the one I got - I'd say 300-450mm would easily be sufficient to get down into the drain holes. https://www.sgs-engineering.com/sbg04-air-blow-gun
