Reading that diagnosis report tells me the dealer is a bunch of goons. This is a problem with the CIC unit, not the combox or amp from what I see on their diagnosis. The only other issue could be the AMP, but it looks like that was already replaced. That first combox that they replaced definitely wasn't defective. Also, why they would check the connections at the USB hub is beyond me, it doesn't even have a MOST connection. Reading that makes me loose faith in BMW technicians, they just press buttons on a computer and don't use their brains to correct a problem w/ a car. Has absolutely nothing to do with EDC as that's not on MOST bus either. It's the CiC or another control unit on the MOST bus.
