S Type Parking Sensors
Discussion
Hi
I have read a lot of threads, and hope someone can give me a bit more guidance.
I have an intermittent fault on my 07 S Type 2.7D with regards to the rear parking sensors.
Sometimes they work, but most of the time they don’t. Up until today, a continuous beep meant ‘not working’, and silence (assuming nothing was behind) meant ‘working’
Whilst the unit is emitting a long beep (but with nothing behind), I have put the car in reverse, and all 4 sensors make the same clicking sound.
I have disconnected the module, and re connected, with no change / improvement.
Today whilst reversing, there was no noise, up until now, no noise has meant that they are working, but this time it didn’t, I reversed into the kids basket ball post, but no damage done!
I am starting to think that it may be the module itself, or possibly a loose connection to a sensor, but I am guessing that all the sensor connections are behind the bumper, so it would be a bumper off job?
A module is about £60 on e-bay, so a lot cheaper than a garage repair even if it doesn't work.
Anyone able to offer any suggestions based on their own experience?
Any help appreciated

Over the last few days I have experienced the following (all when reverse is applied)
Long continuous beep (same as when you are very close to an object, but I wasn't!)
No beep, when I approached an object, sensors worked fine
No beep, when I approached an object I hit it (luckily only the kids basket ball post, so no damage)
A high pitched whistle type beep, no change in tone as object approached
Based on the above, and the fact that when I get a continuous beep all 4 sensors 'crackle' / test out OK, I have ordered a module of E bay for £60. I am working on the fact that it is the easiest bit to change to achieve a solution, and all 4 sensors appear to test out OK, and £60 wouldn't even get a Jag technician to test it, let alone fix it. Can always re-sell if I am wrong.

Module fitted, no change.
All 4 sensors 'clicking' when approached, so left a bit in the dark as to what the problem might be.
Anyone got any instructions as to how the back bumber comes off so I can check the connections? I am assuming that there are a few bolds, and then you have to pull it off, the sides being held on with clips?

Car been to main dealer for some work, and they diagnose the parking sensor fault as rear right sensor.
Anyone know the part number for the sensor, and instructions on how to remove the rear bumper (I assume a few bolts, and then pull hard in certain places?) so I can do the repair.
Seems a better idea than paying them £235, which I guess is a £30 sensor and a couple of hours labour?

Hi Tommo
My car as above was in at the local Jag main dealer and they diagnignosed it as the rear right sensor.
I did a bit of research, and as you suggest, I removed the rear light cluster, and after a bit of fiddling (easier next time now I know how the sensor fits in / comes out!),removed the faulty sensor to get the correct part number etc.
Just to warn you, you would be able to reach the centre ones through the light cluster, but you would need to break through the Polystyrene moulding within the bumper to get to it. Probably easier than removing the bumper, but does it form some sort of crumple zone protection?
My research showed that a working sensor 'crackled', a faulty sensor was silent?
My sensor and paint arrived today, already painted it (3 coats inc clear coat, 3 x 30 seconds, 30 min apart, think Jag MD included drying time in quotation!), so ready for installation at the weekend.
Good luck with yours!

Sensor all fitted and working.
It was the right centre sensor, so not accecible through the light fitting due to the Polystyrene moulding between the body and the bumper.
Managed to find some bumper removal instructions for a pre 05 which were close enough to tell me where all the bolts were.
I managed to just undo the right hand side and move the bumper forward enough to get me hand behind the Polystyrene moulding, which is the route the wiring takes from the main loom.
Quite straight forward, took me about 1 1/2 hours.
A lot better than the MD price

Hi
My car had been to the local Jag garage for cam belt and gear box oil change and they advised me then, I assume they had a computer plugged in?
The sensors are cheap, about £20 each from memory, but if you are doing just one sensor, then the paint will cost you similar money, but still a lot cheaper than paying someone to do it, and plenty of paint left for other jobs?
