Thanks Herbp for your reply, here is an update, battery fully charged and Load test good, removed left rear trim to get at amp and most bus, unplugged and reconnected both amp and most bus module, still no audio, all other idrive functions are working less audio. I noticed that I had red light going in through the blue connector in to the most bus but nothing coming out to brown and green optic connections and fan not operating does this mean the most bus is shot or not getting input? I have live feed into most bus also checked all fuses in car and in rear, all good, anyone out there any more ideas before the dreaded dealer has to be involved ?
Cheers Gaz
