Just picked up a 2011 CTT - what a beast! The torque is insane, and a nice compliment to my high revving 991S.

I am getting a sloshing sound when coming to a stop. Almost sounds like gasoline in the tank! On a 2011 CTT. Any ideas?

You may have the dreaded (yet common) roof rail leak, mine did. Lift the rear cover and check your spare tire compartment for water. I hope you don't find any.

Car drank too much?

I'm hoping that's the cause lol

I don't have roof rails. Can that still be the cause? I've read a bunch of threads on older Cayenne's regarding the drainage tubes being clogged. Any ideas where they are located?

Does the 958 suffer from it too? Mine did it so i permanently removed the 6 plugs in the undercarriage.

Had that sloshing sound in an old X5 ... the A/C drains under the SUV were clogged, and the lower vents filled with water causing the sloshing sound. Although 2011 sounds a bit early for the A/C to get full of crap.

Fix was get under the car, locate the drains, and blast them with compressed air. Stupidly, I was directly under them when I did that ... face full of mouldy A/C water ... but no more sloshing.

Mine made the exact same sound....water leaking from the sunroof drains....drained out, cleaned the sunroof drains and no sound anymore

Any ideas where these drains are located? Any how many of them are they?

In the corners of the sunroof assembly. There are 4 corners and 4 drains.

Had a similar problem on a Touareg, water was trapped between the lower body and the runners underneath, had to remove a plug to drain them.

Also make sure you don't have this problem. Same design feature as the cayenne.
