Hi
I have an issue with my audio system as mist of the features stopped
Working!
Everything was working fine few weeks ago and all of a sudden they stopped.
When I go to phone menu, it just shows Please Wait.
Cd changer is there But shows uncategorized.
Aux selectable but no audio
Usb charges but not reading anything
Tv only got one channel!
I replaced the the MULF2 Hi-bias module and still no luck
Is there a way to check via ncs expert or inpa?
I have a 2009 e92 335i with cic I drive.
Thanks in advance

Sounds like one of the devices in he Most Loop stopped working.
Do you have a Logic 7 amplifier?
I take it you have idrive , Logic 7 and the options you listed
but to be sure you should list a printout of your options with
a Free BMW online vin checker.
The most common problem with loss of sound is the amp getting wet
in the trunk.
Next most common one of the devices in the Most Bus loop goes bad.

If you replace a module its needs programming for your car most
of the time.

Moving a Most jumper through the system as described in the video
is the most common way to isolate the problem.

Since you have the Hi Fi system which is not part of the most
Loop you can concentrate on the other most devices.
Cd changer in the trunk is a most device , mulf or sat module
since you are in Australia I don't know if you have something
like DAB which could also be part of the Most Bus.

S825A Radio control Oceania (this seems to be an Australia option)
Do you know what it is?

Most jumper troubleshooting for these modules would be the first
thing I would do.

You might want to substitute the following for your cd changer if its
bad.

Also you could just bypass the cd changer by routing it out of the most bus.

Aux and USB do come from the mulf .
In the US if there is SOS the cars sometimes come with both a TCU
and MULF instead of a MULF 2 Hi .(not sure about the exact reasons
why)

Hi Fi amps can still get wet but they should only stop the sound no
SOS or other error's
