986 not another leak issue !

[Boxjam]

Hello everyone this is my first post, hopefully someone maybe able to help.

I am new to the boxster world and love my car but for one persistent issue, the dreaded wet carpet behind the drivers seat. I have spent many hours , days weeks searching the internet and checked all the classic places inc all the drain points , doors, seals etc etc..... with no luck.

I have traced where the water comes into the cabin from the inner rear wing behind the seatbelt carpeted bolster. I have ran a hosepipe direct into both rear drains and all runs fine, filled the collection tray and runs fine with no leaks. But after rainfall water appears from the inner wing again. I've sat in the car when raining and checked the rear curtain rail etc and to be honest the roof seems excellent as no water even come in there . I've checked the door before I realised it was cominging  into the rear wing and all was fine there too. I taken out the tray in the rear above the drain pipe and even that's dry. I really have run out of ideas? Even checked it's not coolant fluid.

Any suggestions other than keeping a towel in the car which I'm doing at present.

Thankyou

Believe it or not , mine had a "dead" area in the door seal, by the mirror. I had the same issues and finally checked the seal with the ol dollar bill teuck and found it.

1) It leaked in around the mirror and hafl way down the front

2) Followed the radius of the doorto the bottom

3) Dripped onto the rocker panel carpet on the rear half and wicked all the way to the floor carpet behind the seat. 

 

Have you also noticed the top of the interior rocker panel trim wet after a rain? Thats a dead giveaway... see photo

 

In my experience, German plastics and rubber products are junk on these cars...

Thankyou for the reply, yes I have looked as this area. I have taken out the trim to find it's definitely coming in from the inner rear wing but thanks for your suggestion

Update for ideas please.

 

Even with a half roof cover the water is still getting in from somewhere.

Update. Even though the drain tubes allowed water through they were not as clear as they could be . This was corrected by a local Porsche specialist who identified that after heavy rain they backed up as couldn't cope. So although I thought I had checked this it was definitely worth letting the experience guys check. Thankyou.
