Hello. Just wondering if anyone else has experienced this problem which has just occurred recently - about the same time as my warranty ran out! About three weeks ago, when I was reverse parallel parking into a space the rear parking sensor system beeped rapidly regardless of how far away I was from objects to the rear of the car. The next day this issue had gone and did not come back again until this Tuesday when it started doing exactly the same; regardless of how far ther car is away from any objects to the rear of the car, the parking system beeps rapidly. The info display on the dash indicates that the non-existent object is to the rear of the car and directly behind. The front parking sensors work fine. Wednesday the issue had gone again. Today, it's back again. I have tried switching the parking sensors off and on again, then off and switch the ingition completely off and back on and switch the sensors on again but this doesn't seem to help; it'll just stop when it wants and then start again when it feels like it. I've cleaned the surface of the sensors there tonight, but haven't had chance to test it but will later. The system uses ultrasound (I think? correct me if I'm wrong) so not sure if dirt/salt spray on the sensors will effect their operation. I think it also seems to start when it's dark but that may be coincidental. It's not really a major issue as still have the rear view camera but it does make you wonder sometimes if you've not seen something which can be distracting when reversing, particularly in areas of busy traffic. Cheers!
