As soon as it's in reverse there's a constant tone, But sometimes as you come closer to something they start beeping again, Then the constant tone sometimes starts again then it's fine again, Annoying most definitely.

Considering unplugging them at this rate...

Any idea what's up with it?, Has the ParkPilot box had it

Dodgy sensor or dodgy connection to a sensor.

If you touch the sensor lightly with your finger, its should tick. No tick, no worky. Then bumper off, check the wiring and connections, test again. Still no tick. New/other sensor.

They can be a bit sensitive, pardon the pun, if they are a bit tight in the bumper hole. Of its been re painted for instance.

Thanks for the tip Chris 

[Mr.OmegaMan]

If it turns out to be a dodgy sensor or more than one does anyone have any known working sensors in Nocturno Blue for a FL saloon, Long shot I know

It needs to be in reverse obviously, so engine off .... and the lightness of touch is key, but they do tick.

There's also a diagnostic procedure, involving unplugging a fuse type thing in the purple(?) socket on the loom, but you shouldn't need it.

Aye I did try that earlier walking all directions behind the car, I must have looked like, Well.. Not sure.. Must have been amusing if anyone was watching.. 

Tried pulling that purple fuse out and back in again didn't notice anything different. Sure I did that last year it made all kinds of beeping noises...

Could it be wired into the drivers door tweeter wiring by the Bose amp?

You can use that tweeter solely for the Parkpilot but not in conjunction with the rest of the Bose as you have to remove the resistor from said tweeter.
I removed this and soldered the two pieces of wire together

[chrisgixer]

Ah, yes Bose runs on funny ohms or summat?

Nowt to do with that Chris. If the resistor is left wired on the tweeter you don`t get any noise from it when used with the Parkpilot

[Magwheels]

That's not a resistor its a capacitor. It will filter lower than specified frequencies.

Does it do it when its wet?

Do you have a towbar with a plastic cap?

My old Signum used to go funny in the wet, a wipe over helped, it also had a removable towbar and with the swan neck in place it was fine, but if I put the plastic cap/ cover on and it was on a bit of an angle it used to cause the constant tone, luckily with the Vectra C/ Signum theres a button on the dash so you can turn it off!! (or indeed on if you are travelling under 10mph forwards)
