Reverse parking sensor problems!

[Garry]

Hi

I have a reverse parking sensor problem and wondered in anyone had any ideas as to what is causing it. My DS3 was put on a diagnostic machine as the reverse parking sensors stopped working. Two new sensors were installed. Now the sensors work when I set off on a journey but by the time I get there they have stopped working! The mechanic has checked the wiring but says he can not find anything wrong and is at a loss what to do next! Grateful for any ideas. Garry

Might be a daft statement, but have you tried disconnecting the battery and letting the system reset? I mean for a good 10 minutes.
Mine is an aftermarket (Fitted by Citroen) reversing sensor system, and made a few strange noises a month back, but was fine after a reset (Touch wood)
