Instrument cluster display or MIB system performs intermittent reset. Customer may report that the instrument cluster center display and/or the MIB system briefly perform a reset or cut out. DTC entries for ?optical data bus, interruption, sporadic? are logged in control units connected to the MOST bus. On A6 and A7 vehicles with PR code 9Q8 (Top instrument cluster), a software condition can cause the instrument cluster to cause disturbances on the MOST bus, causing the MMI to reboot. New software in the instrument cluster control module, J285 (address word 17), addressed the condition.
