Rear Park Aid Speaker Muted

[BSM]

The loud squark that the rear parking aid speaker used to make has suddenly become muted. I can barely hear it beeping when reversing into a park.

I checked to see if there was some huge mattress that I'd stuffed in the back, and forgotten about, but no. Nothing in the back at all.:)

Do these speakers fail at all?. Does anybody know how to remove the C-pillar trim to take a look?. Do you need to remove the big torx head seat belt mounting bolt to get the trim off?

[rufusking]

This should help you get behind the interior trim. As for the speaker failing, haven't heard of that before.

RPDC speaker failing isn't an unheard of thing, quite a common thing with the older vehicles now, speaker filling with dust etc.

About $20-30 easy fix.

Isn't the volume controlled by the audio unit? Mine is, but I have the Tech Pack so there may a difference if you don't. Have you tried adjusting the audio volume control when the system is active.

I don't think so. I just checked the wiring diagram. There's no involvement of the head unit volume in the circuit at all.

Yes.....I adjust the volume of my reversing sensors this way.

I also adjust the volume of my parking sensors with the volume buttons on the steering wheel.

Must be a fancy D4 innovation then. I'll check the old girl and see if she can perform this trick, but I doubt it.

Earlier D4s, it couldn't be adjusted my MY13 it can be. Not sure when that change occurred between MY10 and 13.

Mine failed recently. Was making a squeaking sound, then no sound. Caused the PDC light to stay on in the dash as well. Pretty cheap part and quite easy to replace if you follow the Topix instructions to remove the rear panel. I was told it was the ECU that failed so I had ordered one of those as well but it wasn't needed. I have a ECU available for sale if anyone needs one:D

I replaced the park aid speaker this morning. What used to sound like a dying cockatoo being strangled, now has the sweet electronic beep of a modern airliners seat-belts-off signal.

Not a hard job, but you need a 50mm torx head driver to undo the seat belt anchor bolt. Also i followed the instructions provided by rufusking above, which said to throw away that anchor bolt and replace with new. However the replacement bolt provided by the dealer was not the right bolt. Too short. I think they misunderstood me and gave me the anchor bolt for the rear most seat belts, not the middle seat belts. So as it is the old bolt had gone back in.

Oh yes, one other thing. The speaker is on the passenger side (in a RHD vehicle).
