Hi,

 

the reverse speaker was playing fine. then it started to sound a bit muffled/interference when beeping. this got worse and worse until it didnt so much beep but make a horrible white noise style sound when trying to play the beep tone. a bit like the sound form dial up modems lol (but one consistent tone and not a scale of horrible muffled/interfernce noise). Then it sometimes wouldnt play any noise. these last few days i havent heard it at all.

 

What could this be?

 

I initially thought i just need a new speaker.

 

Now i think perhaps its what ever powers the speaker needs replacing?

 

Could it be loose wiring which has slowly been slipping off connection to the speaker and now has completly come off?

 

i cannot find any info about the reverse sensor sytem. I do know that the speaker is located in the nearside pilar between the front and back door. or at least thats where it sounds like the noise is coming from.

 

any ideas of where to start to resolve this?

 

Thanks

best to get a scan done as it could be one of the sensors

The speaker is in the 'B' pillar where you say it is and the trim not too difficult to get off (in the right order).

It does sound like the speaker is going, but I agree with Ed to get it scanned with VCDS prior to pulling trim or spending money as this will help to locate the problem first.
