CCC is flashed with ICOM.
With K + DCAN it usually comes to error messages and breaks off.
And an order must be kept.

RE: BMW E70 CCC failed after update
When chips get to hot (which could be while programming) they loose contact with pcb or have internal connection problems. Usually BGA flash and sh4 processors fail on them.
But before freezing things down try to get an icom with MOST adapter and flash with ista p
