Mmi no sound


Recommended Posts

Steve when you operate the steering wheel volume buttons or the swivel on the centre console do you see the volume bar appear and go up or down?

If it does appear can you visually get the bar to move or is it just stuck with no sound?

Reason why I ask is there is a some-what known fault that involves the steering wheel volume and voice control switch to stop working either wiring or the switch itself no longer responds to the control unit, causing the volume to mute or stay low and what ever attempt to adjust this doesn't work. 

As indicated if you plug into a diagnostic machine, your likely get a code relating to a communication bus error indicating where the gremlin may exist.

If a fuse as blown id be very worried, as this indicates a lot worse a problem that may be concealed, the fuse blowing is typically a secondary fault to the initial fault.
