Service bulletin Update 90K2

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

On Audi A4, A5 and Q5 vehicles manufactured within a specific period, the service interval display does not show all parameters. As a result, the number of days remaining until the next service is due are not displayed correctly.
