Peugeot 107 audio system failure

Hey! I had a similar issue with my 107. Does the display unit light up at all? Have you tried using the auxiliary input or USB audio to see if the issue persists across different audio sources? Sometimes, it can help isolate whether it's a speaker or head unit issue.

Thanks for your reply! Yes, the display unit lights up and seems to function normally, but there's just no sound. I haven't tried the auxiliary input yet, but I did try a USB stick with music, and that didn't produce any sound either. Could a defective bass speaker really cause the entire system to go silent?

Alright, that's quite similar to what I experienced. And yes, a defective bass speaker could potentially cause the whole system to shut down, especially if it's shorting something out. However, given that the USB audio isn't working either, it's more likely a problem with the head unit itself. I would recommend taking it to a workshop to get it properly diagnosed. They'll have the right tools to check the wiring and the unit.

Thank you very much for your help and advice! I took it to a workshop as you suggested, and it turned out to be a faulty head unit, which was impacting all audio outputs. Repair cost me 280€. Appreciate you pointing me in the right direction!
