Parking Aid Warning Chime (H15) Loation?

[Quattros]

My rear beep has gone... did a scan and threw the code:

10543 Parking Aid Warning Chime (H15)

have done a check and all rear bumper sensors are working fine through vcds so leaves the actual speaker it self?..

any help on where it is, and part number, and a quick guide to remove and refit?
thanks guys..

anyone, i have had a look under the rear shelf but cant see anything, just moved seats forward and un clipped the front of the shelf.. enough to remove the sound proof material, only thing tere is the light connection for boot..

Should be rear left, accessed behind the side-cover.
Stick a bit of tape over a sensor then switch on the parking sensors while you follow the sound in the back to find the speaker.

I have the following fault through VCDS
I own an Audi A6 2004 have not had it for long so have no idea where to start on this error
any ideas on where to find the chime speaker or what to test as there is no beeps or any sound from it at all, so cant trace where it is
I also noticed that one on the sensors on the rear bumper is slightly recessed compared to the rest, could this be a problem?
