I have a 2010 XF 3L V6 diesel with 99000 miles.

While the engine is idling I can hear a gurgling sound, I presume its water just by the sound.

I don't have any cooling warning lights showing up on the dash and I don't see any noticeable leaks?

When I rev the engine I don't notice any higher gurgling sounds, it's just when the engine is idling.

Also the keyless entry system will lock the car but will not unlock it, is this just a setting in the system?

 

Could the gurgling sound be your a/c ?

 

Humm possible, I'll check that in the morning!

I just noticed the passenger door will open keyless but the driver's door won't!
