I have a 2005 xtype estate, Its also got a problem on the module. They are bad for getting damp in the tyre well. I got it checked and the sensors on the rear are ok its definitely the module and you must get the exact same part number replacement. They cost £150 from Jaguar, another of their rip offs, You may get one on e bay about £80. I am still looking 4x43 15K866 AD. If anyone has a spare please let me know.

For what it's worth, the problem on mine turned out to be the speaker itself. No surprise; it's on the back package deck so it's exposed to sun constantly. Here's a fun fact: the same part is used by Ford ($8.49), Jaguar ($48), and Nissan ($86!!). Ford was backordered, but I found a dealer in Ohio that had one in stock and they kindly mailed it to me for $6.

I think my rear parking assist was working when I got the car, but everything was new to me then so I can't be absolutely sure, However they are no longer working.
Reading here about the 3 second tone and the clicking of the sensors, I checked, and there is a loud 3 second tone coming from the back when it is first shifted into reverse, but no messages and no CEL. I had my wife start the car and put it in reverse with her foot on the brake while I checked the rear sensors with a stethoscope. Three of them do click, but the far right hand one does not, so I assume that is the problem.
Am I correct in assuming one malfunctioning sensor would disable the rear system? (the front ones work fine) Is there any good way to test a single sensor? Might it be a matter of wiring? I looked in the boot and everything there looks clean and neat. Is the sensor control one of the two boxes mounted on the left side wall by the tire? Any suggestions will be appreciated

edit: disconnected and sprayed contact cleaner in the two connectors along the back of the boot and removed the parking aid module, but I can't figure out how to disconnect the plug. The manual is very helpful in that it just says "Disconnect the parking aid module electrical connector." I can't find a release of any kind. Anyone know how this comes off?

Edit: Is it possible to get to the individual sensor connectors without removing the bumber cover? (hope, Hope)

My sincere apologies; I never saw this inquiry. For anyone running across this post, the Ford part number for the parking assist rear speaker that was used (at least) on the 2004 XJ is 3W8Z15K864A.
