EMehari MOST Bus Failure
Summary of the thread
A 2018 Citroen EMehari is experiencing a failure in the MOST bus, leading to a loss of audio, system functionality, and navigation. The problem is suspected to be related to a control unit interfering with data transmission. While fuses have been checked and found to be in order, diagnosing the specific faulty module without specialized equipment is challenging. It is recommended to take the vehicle to a workshop for proper diagnostics and repair.

Yeah, fuses were the first thing I checked, all good. Is there any way to diagnose which control unit is causing the issue without tearing everything apart?

Without specialized equipment, pinpointing the faulty module can be tricky. MOST bus diagnostics often requires dealer-level tools. Given the symptoms, it's probably best to get it to a workshop.

Cheers for the confirmation. I was hoping to avoid the shop. Looks like a 1000€ repair to fix the MOST bus issue, just what I needed!

MOST bus issues can be a pain. Have you checked the fuses related to the audio system and the control units on the bus?
