Service bulletin LI54.30-P-070030
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
After starting the engine, the instrument cluster display (A40/16) may show "4MATIC inoperative" erroneously.Notes: Vehicles not equipped with 4MATIC are predominantly affected. However, in some circumstances a 4MATIC vehicle can also display this message. Previous software release of the instrument cluster control unit (N133/1) Ensure that no complaints exist regarding the 4MATIC system. If no other complaints exist, perform a software update of the instrument cluster control unit (N133/1).
