seefive Posted October 15, 2013 Posted October 15, 2013 Have you checked the sensors, to see if one is loose or dislocated? This would create a constant sound,if a sensor is hanging down and sensing the road Quote
denenicholls Posted October 15, 2013 Author Posted October 15, 2013 they look like they are in normal position, the car does beep as soon as i drive off for quite a while. Quote
denenicholls Posted October 15, 2013 Author Posted October 15, 2013 i ahve only had the car 1 month, surely the garage should resolve the issue? Quote
paul.h Posted October 15, 2013 Posted October 15, 2013 A Citroen dealer warranty is 12 months but other garages often give 3 months and then you can purchase an insurance policy for longer. So, as you suggest, your car should be covered by its warranty so I would get in touch with them. First though, has there ever been a display from the front sensors since it is possible they are not an original factory fitting and may be aftermarket ones which are unlikely to give a display, just the beeping noises - do the beeping noises come from the same location as the rear sensors or from a separate beeper somewhere behind the dash. You can check the original car characteristics on the service.citroen website using your VIN but you will need to register as another professional, member of the Citroen Owners Club. This will also allow you to see the Citroen parts diagrams. I have a Jan 2009 C5 brochure and in it only rear parking sensors are standard on the exclusive model, so may be front sensors have only been an option on the new C5. Quote
denenicholls Posted October 15, 2013 Author Posted October 15, 2013 They may have been optional extra and appears to be one box in boot with two sets wires coming out assuming one front n one back, does professional membership cost so I can check with citroen? Iv only just bought it second hand so don't no if it used to show a picture Quote
paul.h Posted October 15, 2013 Posted October 15, 2013 Using service.citroen is free for things already mentioned but you can purchase procedures and other things but I have never done that. Quote
tco_tm Posted April 10, 2014 Posted April 10, 2014 Hello to everybody. I have a similar problem with a 2005 C5 Break 3.0 A/T with RT3 navigation unit. Front sensors are giving audible signals only when I put gear selector in a reverse. Signal is proper, coming from adequate speakers, changing from continuous pitch to beeps emitted in raising intervals while I am backing up from obstacle. If gear selector is in drive, there are no signals at all. All this time navigation display shows wrong information - only the farthest central segment if obstacle is very near. Rear sensors are working normally. Someone on different forum described exactly the same behaviour. I think it is related to RT3 or BSI malfunction. I replaced sensors, front harness and parking assistance unit (placed in a spare wheel bay) and also updated RT3 software using image on CD, but it gave no results. My next step will be putting my assistance unit into another C5 to check if it is not damaged. I will also try to give my car to authorized service for complex reprogramming, but I worry they won't to anything more than telecoding (what I can do manually, step by step with my lexia clone). Regards,Pawel P.S. I know this thread is quite old, but maybe with your help this strange problem will be finally solved. Quote
tco_tm Posted April 14, 2014 Posted April 14, 2014 Well, three days after posting above and after three months of investigation, problem of bad readings from front sensors is solved. The solution is to reconfigure parking aid module with software other than Lexia/Diagbox delivered with poor's man PSA VCI. I used Peugeot Planet 2000 (versions 21.xx and 22.xx works for sure). The problem is not in a car, but in a bug in diagnostic tool, which writes rubbish into parking assistance unit during configuration. If someone tried to diagnose damaged parking sensors before and e.g. turn them off with use of this software, there is 100% certainty that after that operation signaling of obstacles in front of the car will not work properly. I described in details my adventure with parking sensors on other forum, maybe it will help someone: http://www.frenchcarforum.co.uk/forum/viewtopic.php?p=405435#p405435 Regards,Pawel Quote
paul.h Posted April 29, 2014 Posted April 29, 2014 Welcome to the forum and thankyou for this information, definately something to be aware of if a parking sensor fault occurs and a copy Lexia is used. Quote
iulian.arg Posted June 19, 2017 Posted June 19, 2017 Hello I've recently had (created myself) this problem with front parking sensors and, thanks to this forum, I've solved it.But one thing to note is that I needed an older version of PP2000 to make it work: v. 22.xx.Version 25.01 didn't work. So, use version ~22.xx to fix it. You may try newer versions as well, but if unsuccessful, switch to older versions.Probably there are older versions of Lexia working as well because both PP2000 and Lexia share common software subroutines.
