Rear boot carpet soaked and condensation on boot lid

[emohawk11]

This happens after lots of rain.

The coolant level is always at full and never goes down.

Last time I checked the interior carpets were dry.

I'm thinking about stripping back all of the boot carpet, but is there anything I can check to find out where the rain water is getting in from??

thanks.

By boot I guess you mean what we call the trunk. The obvious intrusion points are the weatherstripping, the fit of the trunk onto the weatherstripping and the area around the rear tail lights where they mount to the body (a weatherstripping of foam is supposed to be compressed between the two but if not there would be an intrusion point).

How was it parked...would the angle give a clue?

aha in future I will refer to it as the trunk.

The car is always parked flat, but there appears to be MORE water on the lower carpet by the rear light cluster on the nearside.

There is now condensation on the inside glass of each rear light cluster too!

Can you give a step by step instruction guide on what to check / remove? the Porsche specialist is £60 per hour plus VAT!

thanks

Mate, why not get in the trunk/boot and have someone put the hose on the rear taillight area. If that does not leak then try around the weather seal. Shouldn't be too hard to find.
Also check where the grommets go through to the engine bay.

Take the carpet out of the rear boot and use it as a template. Get some sheets of brown butchers paper and using the carpet as a template cut several paper inserts.


Install the paper, shut the boot, and spray the area with water. Wait a minute or two then check the paper and see if it's wet. From there you should be able to trace back to the source of the leak.

My first guess is a faulty tail light gasket.

have you seen the size of the trunk? It's tiny !! A normal size human cannot fit in there !!

And obvious once you get your head in there. Don't be afraid of a Porsche. It is just a car in lots of aspects and replacing a tail light bulb is about 1 on a 10 scale of difficulty.

Open the trunk/boot lid. Remove any lining. Unclip the lights and their electric circuit board. Now remove 3 nuts holding the tail light to the body. Examine the foam that compresses between the tail light and the body. Pictures Page 226 my owner's manual.
