C5 Parking Sensors

[mickrochip]

hello there,

                 problem with parking sensors on 2004 2.0l hdi 16v c5.

                problem appears when car switched on , parking system faulty, was  wondering if there was any way of testing individual sensors,this system was excellent when working , especially for parking in tight spots,

                 maybe would need to take car to dealer for digonostic check

                   thanks for now

You probably have a sensor faulty. A lexia will indicate which one, although I've heard that a buzzing noise can be heard from good ones.

thanks for the help lads, 

 another question , are the front & back sensors interchangeable,or do i have to get rear sensors

[Johndouglas]

Looks as though they are all the same with the same part number - 6590 A5

thanks for your help , i think it is one of the rear sensors,it  happens when car is put into reverse gear

thanks for all the help lads,

                                   after diagnostic check , found rear sensors were at fault. water ingress was the problem.changed the four i had in a spare front bumper to the rear, every thing looks o.k at the minute

                          so thanks again for your wealth of knowledge and experince
