Citroen C5 Tourer 2.2 Parking Sensors

Post by gummibear1 » 10 May 2018, 17:50

Can anybody tell me why my reverse Park sensors just give a continual beep and do not work?

I assume you are talking about a C5 X7, as you have used 'Tourer'.

The continuous beep will probably be caused by a malfunction of one or more of the ultrasonic sensors. Another possibility is that there has been some liquid spilt in the boot and this may have got into the Parking Assistance ECU which is mounted on the rear right of the loading area - under the boot lining.

It will need connecting to a Lexia with Diagbox to determine the exact sensor that is playing up - if it is this, or it will provide a clue to the fault if not.
