liquid dripping from rear left hand side

[colinmartin]

hi

I have liquid dripping from the rear left hand side behind the rear wheel arch I think its washer fluid what is the easiest way to see the washer tube for the rear wash/wipe ,it seems to drip whether I use the rear washers or not..

Remove the most rear part of the headliner, this with the light, the rubber hose of the washer is visible using a flashlight and possibly a mirror, probably the hose is jumped from the nosle or the intermediate part. With a fine nose pliers you can get it there again, if the hose is not torn up or stretched open on the connection section. Take a good look if there is no water damage to any existing electronic control boxes.

Does your Cayenne have the 4-zone air conditioning option?  If so, it's normal for the condensation from the rear A/C unit to drain behind the driver's side rear wheel.

I just actually just posted a similar issue "a mystery leak".  I also have the 4 zone air conditioning option (08 CTT) but I have never seen it 'leak' like this before in all the years I've had my car.  Thats why I was perplexed.  I originally thought it was some sort of ac drain issue but then I couldn't figure out why I only saw it next to the driver's side rear wheel. In fact, I actually never ANY condensation under my CTT so that's why it was odd to see it a couple times now- only in the rear.  (And I'm starting to see a bit of a stain on the concrete too.)  

 

While one of the other posts mentions a fuel pump/flange leak, the one thing I don't have is the smell of gasoline.  Therefore, I am starting to think it has to be something else....
