I have driven only 8mls in my 'new' 2011 Octavia (1.6MPI) and so far its only disagreeable feature is the audio level when reversing. I see in the instructions for the Bolero unit, that this should be controllable in the Tone/Balance setup. I had already discovered that the 'optional equipment' listed in the Service Schedule included the code 7X0 - Without Park Distance Control, so I was not surprised to find that the control does not exist.

The visible parts of the PDC system (the sensors and four wires through a grommet into the bumper area) show every indication of having been factory fitted, but I suppose it is possible it could have been fitted as an afterthought. Can anyone suggest somewhere else where this sound might be controllable?

The sound appears to come from the vicinity of the rear roof light, where the roof lining seems rather hollow. If the control unit is in here, maybe I could mask it with some sound deadening foam (unless someone can suggest a better plan).

When they're active, does it show up on the screen of the bolero?

If they do, the PDC volume should be a setting in the maxidot trip computer.

Thanks for the reply. I don't see anything on the Bolero. I am sure I do not have a Maxidot display -, at least I have never been able to get any sort of menu.

If there is nothing on the bolero display then it looks like an aftermarket kit has been fitted.

Some foam over the speaker sounds like the easiest of solutions.

It might be easiest to drop the headlining slightly from the boot opening of the car and find it tucked up there.

I think you are right, though the paint over the sensors shows no evidence of having been painted after the rest of the bumper was sprayed.

I'll see tomorrow if I can get the interior light off, since that is where the sound is coming from.

I took off the rear roof-light. Of course there was nothing behind. The sound was coming from much further back. It was then I noticed a little loud-speaker, glued to a plastic trim panel to the near-side of the parcel-shelf. I fixed some thin self-adhesive felt on it. The sound is still plenty loud enough, but a lot less painful!

It's a bodge that rather offends me. If I can get motivated enough I will try to detach the carpet below the speaker to see if the control unit is in there. Possibly there might be a sound level pre-set but I have met a similar device previously and there wasn't on that.

If it was just on top of the trim, no wonder it was so loud. Even the aftermarket kits are designed for the speaker to go behind a piece of trim.
