Solving the wet Cayenne Carpet Conundrum

Finally found and solved the wet carpet problem.

Without my normal waffle – it was the drain tube from the Air Conditioning. This is a rubber hose with a semi-sealed end with a cut/slit or burper opening. The end was blocked, or had sealed itself shut, apparently a common problem with older Cayennes that have heavy AC use. So, after driving around with aircon running, the cold condensation builds up and has no where to drain to. It sits in a little overflow tank until it finally fills up and floods out on drivers (and passengers feet) when cornering. Sound familiar? If so, then this video will help fix it.

It’s a simple job – one screw look for the hose, found it, opened it, sprayed some lube (WD40) to stop it sticking shut again and *boom* aircon is properly draining and no more wet carpet.

Wet Porsche Cayenne Floor Mats?

Wet carpet on drivers side?

The story so far – I had a drip-drip-drip onto my drivers side carpet. I didnt think too much about it. Until the car died with a massive electrical brain fart which turned out to be caused by the gradual buildup of moisture under the carpet. This moisture eventually corroded some wires hiding down there and caused an electrical nightmare.

This is my first try at fixing it – which didnt solve the dripping carpet problem but did find and unblock some other water drain holes. Definitely something I would recommend to any Cayenne owner – it’s easy and just took a few minutes to do:

After a bit of trial and error — I finally solved the wet floor mat problem. Mine was caused by a blocked AC OVERFLOW VALVE but my first attempt at finding it (this video) was cleaning the other drainage holes. It’s a quick easy fix so check it out here https://www.motolimey.com/solving-the-wet-cayenne-carpet-conundrum/

Need to do 2 things (1) clear the rubber draining holes and (2) clear the air-conditioning evap tube (next video)

or in the words of the Donald… “drain that swamp”

WET FEET with a Porsche Cayenne

I’ve had this little drip-drip-drip on the front floor of the Cayenne for about a year.

It only seemed to happen after hot weather and lots of aircon use.

It never seemed to be a problem.

Just goes to show how wrong I am at times.

hashtag epicly wrong.

Long Story Short

The occasional drip drip (onto the drivers foot and also sometimes passengers foot) slowly soaks into floor mats. Overtime this is trapped under the floor mats in the hugely spongy underlay.

This leads to water damage and corrosion of some electrical wires under there. These corroded wires will eventually (incorrectly) send bad signals to the engine computer which then lights up the dashboard like a Christmas tree and scares you half to death: warnings of Brake Proportioning, ABS Failure, Key not recognized and some others.

But don’t panic – help is easy for anyone with some basic tools and the urge to fix it themselves (rather than the $1800 I was quoted by Porsche)

Solution

  • Pull up drivers carpet and dry out the damp – clean and reconnect the wiring (which is really easy) and boom Chrimbo Lights should be fixed
  • Now clear out the drain ports under the Cayenne (or Tourag) – another easy job that just needs a couple of screws being undone
  • Now clear out the AC Drain hose in the cabin. This little rubber hose blocks itself and is the main culprit for the wet carpets – another easy job which only takes a few minutes.

It took me a lot of trial and error to find these culprits but it’s done and I managed to video each part. I will edit a video together showing how to do it. It’s really very simple. This definitely seems to be a design flaw from the Porsche Peeps and hopefully my solution will help some other folks out…

UPDATE – I found the DRIP DRIP DRIP and fixed it.
