Intermittent sound system issues

[YouStoleMyMash]

Hi guys, 

I have a 2005 320i SE (E90). I have had it for about 3 years, and when I first got it, I had problems with the sound system randomly cutting out for a random period of time. It wouldn't matter which source I was using, I.e. Radio, CD or AUX. 

Then it sort of fixed itself and worked without fault for about a year and a half. 

But now the problem is back!! I have no idea what would be causing it, there are no fault codes showing when I plug a reader in, and as I said it does it no matter which source I am using...

It is driving me mad and I'm hoping someone has a solution for me!

Thanks in advance

Does the power to cut completely?  e.g. does the illumination on the system go out completely or is it still powered up but with no sound coming through it?

Hi Trevor,

I have the model with the iDrive. The screen stays on but no sound comes through it

Thanks for the reply

I'd be tempted to remove the system and check the wiring and connections behind.

Had a look at the back of the radio, and everything seems to be connected fine. Not sure what else to do....
