Service bulletin A901558 2042388-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Customer may report that the instrument cluster center display and/or the MIB system briefly perform a reset or cut out. DTC U10CC00 (Optical data bus for digital sound system sporadic disruption) is stored in the information electronics control module. 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.
