Peugeot 108: Crackling noises from radio speakers when mobile telephone connected to universal serial bus (USB) socket
We are having difficulty diagnosing a crackling noise from the radio speakers when a mobile telephone is connected to the universal serial bus (USB) socket on a 2014 Peugeot 108. There are no trouble codes stored and we have visually checked the wires to the audio unit but have not found the cause of the fault. We are hesitant to replace any components in case a software update will fix the fault. Can you assist us?
Yes, we have come across this fault before and it affects all 108 models with a universal serial bus (USB) socket up to 10/05/17. The cause is likely to be due to an internal fault with the audio unit. Remove the audio unit. Locate the identification label on the audio unit and check the version code. If the version code is not N, replace the audio unit with a modified version. This should rectify the fault.
