Service bulletin A901557 2042121-
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
The head-up display will not power on or does not work. After the next bus silence (for example, waiting five minutes after the driver side door is locked), the head-up display works correctly. There is a software deviation that affects software versions 0304 (on A6 and A7 vehicles) and 0021 (on A8 vehicles).
