Rear obstacle detection was part of the Technology Package on the C6 A6. But the Technology Package was discontinued a few years ago.

Is this feature now part of the Prestige Package, as some sources suggest, or is it no longer available? When looking at photos of A6s with the Prestige Package I see none with sensors in the rear bumper.

If you have a 2009 or later A6 with rear obstacle detection, what model year and which package, Premium, Premium Plus, or Prestige?
