Hi

I have recently purchased a 2018 levante 3.0d and love it so far.

I noticed yesterday that the rear park sensors aren’t working. It turns out the sensors themselves are working you can feel them pulse if you run your finger over them when you put in to reverse, the display on the dash is working and displaying red when you obstruct the sensors but there is no sound.

I have plugged in a diagnostics computer and read the codes and it has came up with B1408-13 rear left audio speaker output open circuit and B140C-13 rear right audio speaker output open circuit.

I then faded the audio on the touch screen to the rear and only the rear small tweeters in the door are working, the main speakers are off? This must be where the beeping comes from for the rear parking sensors.

The front sensors are working perfectly.

Any suggestions?

Thanks

Tom
