Peugeot Partner audio navigation failure

Hi, I have a 2019 Peugeot Partner (electric). Since today, the audio system and navigation don't work. No audio output at all. There’s also a MOST bus fault error. Has anyone had similar problems?

A 2019 Peugeot Partner electric vehicle is experiencing a complete failure of its audio and navigation systems, accompanied by a MOST bus fault error. The issue may be due to a defect in one of the control units within the MOST bus, a fiber optic network for data transmission. A similar problem was resolved by replacing a faulty control unit, which required professional diagnosis and repair. It is advised to take the vehicle to a workshop for proper assessment and repair.

Hey, I had something similar with my Partner! Check the MOST bus - it's a fiber optic network for data transmission between the control units. A defect in one of the control units in the bus network can cause issues with the audio and navigation. Does it happen intermittently or is it a permanent failure?

Thanks for the info! It's a complete and permanent failure. Do you remember what exactly was the problem and how it was resolved?

Yeah, mine was also a permanent failure in the end. Unfortunately, I couldn't fix it myself. I took it to a workshop; they diagnosed a faulty control unit on the MOST bus causing the whole system to crash. Cost me around 1000€ to repair. I'd recommend having it checked out properly.

Okay, thanks for the advice. I'll bring it to a workshop then. Appreciate your help!
