S Type - Access to rear parking sensors
Discussion
This is probably a dumb question.
I have identified (from other post on this site) that I have 1 x faulty rear parking sensor.
How do I gain access to check connections.
I am assuming that I remove the black plastic trim that continues from where the colour of the bumper stops, to the underside of the car, fixed with 4 x plastic screw type fixings under the car.
I started to do this last night, but if this is the route, I need to get some more plastic fixings before I start as 2 of them won't come out without damaging them.
The reason I ask, is that the sensors are still a distance up the bumper, I am just hoping that when this bit is removed, that I don't have to then remove the whole bumper.
If I remember corectly the S-Type has a foam block between the bumper and the beam and at least the inner 2 sensors sit inside cut outs in the foam,
therefore it looks like your going to be removing the bumper ,
unless you are willing to risk a cunning bodge by cutting channels into the foam till you can get enough room to get your hand up to the sensors.

Thanks for your responce, I was beginning to think I was been ignored, or maybe no one knew the answer?
Not the answer I wanted as it is the middle nearside sensor that is not working.
It has come back to life a couple of times which makes me think that possibly it is a loose / croded connection problem @ either the sensor or the control box rather than the sensor it's self.
As it looks like quite a job to check the connections to the sensor, ie bumper removal, have you any idea where the rear parking sensor control box is so I can check that end 1st?

and the 2 we had in the garage were both fitted with hideous aftermarket jobs, sorry OP Im not being alot of help am I . will keep trying thoStill need some help.
Have located the 'black box', no loose wires, no damaged wires.
Using a link from this site I have identified that 1 sensor (nearside centre) is not working (no 'crackling' noise coming from it whilst in reverse).
I am assuming that the sensor is faulty or possibly a loose wire or dirty connection which I would like to check out before buying a new sensor.
My main problem is how to gain access / remove the bumper.
I have tried undoing the 4 x plastic screws on the rear underside, but the underside black plastic trim seems to be well fixed to the bumper, so I assume the whole bumper need to come off?
If anyone can confirm if I need to completly remove the bumper, and if so, how?
The fixings were always so obvious in the days of metal & chrome!
Hi John, you are corect about the sensor ticking. Now if I remember correctly, access can be obtained via removal of the rear lamp assembly. Now, the way we used to do it. We would use a hot air gun, to heat up the palstic tags on the light unit, then just straighten them up so you can remove the lamp assembly. dont over do it as they are quiet fragile, but i never broke one !
once removed you should be able to get your hand down there and get the sensor out, easiest thing to do it swap it with the other n/s one and see what happens, that tells you if its a poor connection, or a faulty sensor. I believe I have some brand new ones in my tool box, which would be prepared to sell to you if your interested. E mail or message me, if you meed any further help. Also check fo water corrosion on the control unit pins, that was very common.
