Could be a multitude of reasons why - best thing to do is get the fault codes and start from there. Plenty of auto Sparks will read and reset codes for £20 -£30 just make sure you get a note of code(s) and some of us here will try to point you in right direction 2014 SE Loire Blue SD4 Auto (MY15)

individual sensors can fail, this will put the system into error, but a front failure shouldn't put the rears in error.

There is only one parking module and its fed from FB1 a 10 amp fuse in the boot fusebox, if its blown then both the front and rear parking sensors are affected.

As said the Fusebox is in the rear next to the spare wheel well.

Checked the fuse and its not that but seen this near to the fuse box and its not connected to anything could this be the fault I bought the car a few wweeks ago so it was like this when I bought it and the sensors have never worked thanks |

I don't know what that plug is for. Under the rear side panel on the left hand side is the parking sensor module, if that plug/loom goes to the module then maybe it is.

That's the plug for the "trailer module". Nothing to do with parking sensors. From what your describing, if you've changed the sensor and still getting a fault then I would be checking with a multi meter whether that circuit was working. Maybe the loom is damaged at that point.

Did you ever get to the bottom of this? My parking sensors, front and rear, have both stopped working. My fault code is B1B42 (Front Left Inner Sensor). When I start the car there I a long beep, similar to that heard when the sensors are activated as when selecting reverse; the beep stops and, if I then select reverse, the button on the centre console will flash but nothing more - no sound/ beeps. If I select Drive and press the button it does the same - no sound/ beeps. |

Park Assist module requires a CAN reset, if you don't have a diagnostic tool to do this then try a hard reset assuming you've replaced the faulty sensor or rectified the short circuit (water ingress).
