Bad news paid £90 today at my local dealer for the park aid module still did not work, looks like the rear bumper willl have to come off, must now be a sensor.

I have checked all my sensors for noise and they all make a clicking sound, what else could be the problem, Module maybe ???

 

Hi, Just noticed my rear parking sensors not working properly. I can only hear the beeping if the radio is "off." My electrical guy says "the sound box may have been dislodged." Any other ideas before it costs me a small fortune. Thanks
