Land Rover Repair: Water Sloshing Sound Passenger Side, green stuff, running water

Question
There is a sound of running water like through pipes in a wall coming from the passenger side. It is heard by all passengers.  There is no water leaking into the passenger side of the car.  The AC works. Additionally, the driver side auto door lock does not lock/unlock with the key with one-click but will lock with a double click of the key... doesn't open with remote key. Any info would be helpful.

Answer
Running water usually means the cooling system is low.  Make sure you fill it properly with the recommended coolant.  Don't mix the red Dex-cool and the green stuff.

The problem with the remote will need dealer or specialist diagnosis, to talk to the alarm
