If you hear a long beep tone (about 4 - 5 seconds) when going into reverse, you have a fault in the reverse parking aid system. This will require you to obtain the code(s) from a dealer level scanner.
Since its intermittent - could be a loose connection at one of the sensors, but the rear bumper will need to be dropped to access harness/sensors.

Anant,
If your car also has a front parking assist system, you should have a switch in the overhead console marked with the letter "P." You can press that button to disable the park assist system, but you have to press it every time you start the car.
If I understand correctly, cars that only have the rear park assist system do not have the overhead switch. I don't know if the park assist system can be disabled using the dealer-level diagnostic system (JLR SDD), but a dealer can tell you.
You may be able to tell if one of the park assist sensors in the rear bumper is not operating by turning the key to Position II (Ignition ON) without starting the engine. With the transmission in PARK, step out of the car and go listen to each of the four sensors. If a sensor is working, it will make a faint clicking sound. If one sensor makes no sound, you've found your problem. It may be the sensor, or as abonano mentioned, it may just be the electrical connection to the sensor, but either way the bumper cover must be removed to access the sensors.
It is very helpful if you add your car's details to your signature so others don't have to guess what model you're inquiring about. Hover your cursor over your username in the upper right corner of this page, and in the dropdown menu click User CP. In your Control Panel, click on Edit Signature in the left column under Settings & Options. Add your car's year, model and engine displacement, then click Save Signature.
Cheers,
Don

I did this and the system stopped annoying me, but it looks like this circuit also controls the electric parking brake. It prompted a parking brake fault, but I was able to get that to go away after reinstalling the fuse and disconnecting the battery for 5 minutes to get it back into relearn mode. I just need to figure out which sensors are bad because mine intermittently work as well. They always work when it's raining for some reason.

Anant,
Great that you found your issue, mine works randomly. I need to check the sensors. When my WDS was working it gave me a code ( cant remember the number) that indicated that there was a ground issue. My WDS has crashed again, so I ordered a JLR/SSD. Will let you know how it works out.
