E61 CD Changer not playing
 

Hi folks, I am interested if anyone has ideas as to why the CD Changer has stopped play CDs. I was able to eject and load the cd caddy without issues. It has recently come back from an oil service and battery recall. I have another thread describing that the bluetooth has also stopped being able to be activated - is this just a coincidence?
Is there any simple things I could check before booking it into the dealers?

I would just go back to the garage where you did the oil service and battery recall and explain this. Might be some electrical issue has raised when they disconnected and reconnected the battery.
