My 2004 Cayenne S has sloshing sound on sudden stop or acceleration. Its carpet on passenger side all way to back is wet. Air con and heater are very good and collant is full. Service light is NOT lit. Drives excellently. What is wrong?

Blocked A/C drain most likely. Condensation dripping inside car, instead of outside/underneath. Alternatively, the passenger side exterior drain may be blocked, permitting rain water/car wash to enter behind dash.

Most likely a blocked exterior drain. Because of leaf and debris drop, I have had this issue 2 or 3 times. It requires someone unclogging the drain hole.

A shot of compressed air will knock the clog out

Clogged fuel filter?
