Front sensor sounds.

Trying to work out what's what here.
Using GAPIID Tool, I have worked out the front sensors are measuring distances ok. The front sounder says it active in live values and I have checked movement on the app. If I go to ccf values and seeing the only mention to bongs or active noises is the key in ignition. I hope that the front sensors emit sounds off the instrument cluster , that's what I understand.
If i enable sounds for the key in ignition barrel and update settings the update fails . I am now thinking the cluster sound buzzer/bell/ **** has stopped working?

Unless I am mistaken and I have been mistaken, I know the rear sensors sound from a small speaker on the drivers side rear panel. My fronts don't work either, but I have other issues that cause this. So the fronts may use the same small speaker, but not sure where it is.

The speaker/sounder for rears is located in the left rear wheel arch , the fronts use the instrument cluster according to the workshop manual.
