Does anyone else get condensation on their 4S cabrio?

Hi, third time in three years that my 2011 has gone for a service, they say water is under the carpets and that the drain holes are blocked.
I am told i cannot clear drain holes
I am also told this happens to most cabrios not kept in a garage
Is this right?
Please help
 
A 2011 911 cabrio should not leak. They might get a bit of residual condensation in if they are kept outside, but this will quickly disperse with use. The carpets should certainly not be wet.

Is this one garage that has told you that 'they all do that'?

The drain holes are easy enough to clear... I'm sure someone here could advise how, or a good garage should be able to do it.

It could be something else, for example the membranes that seal behind the door trims.
 
I'd be interested in learning how to clean the drain holes

Hopefully someone like Alex will be along shortly with a master class

There's two areas you need to check the drain holes. The easy one is around the battery in the frunk. Pop off the plastic cover abouve the battery and you'll see the rubber drain holes at either side.

Read infrasilver's thread here: http://911uk.com/viewtopic.php?t=114712

The other ones of concern run down either side of the rear seats behind the trims (that house the rear speakers). See No. 3 in the diagram below.

GT4 nails it here:


GT4 said:
Very common problem (especially if the car lives outside or is used in the rain, road debris gets washed down the drain holes and blocks them, then the next time it rains the drain holes overflow and water gets in the car).

997 basically = 996:

Rod your drain holes (or you can get OPC to)

Door membranes:

Not a 996 or 997, but this is basically what the membrane is/does:

Do this when any debris may be soft and moist (ie after extended rain, or at a pinch after a decent washing drench).

Use an airline to blow clear, or old springy type plastic coated curtain "rod" (net-curtain wire) - you want it firm enough to push, but flexible enough to go round radii and not puncture the drain tubes with sharp edges:

(remove the hook or eyes!!)

Access (rodding) may be easier via the lower exits.

This is illustrated in the diagrams and the photo of the wheel arch (behind wheel arch liner).

The exits you need to clear look like grommets.
