# Service bulletin NCU\-23P5497107

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

Mercedes\-Benz AG \(“MBAG”\), the manufacturer of Mercedes\-Benz vehicles, has determined that on certain MY 2021 S\-Class \(223 platform\) vehicles, the software for the communication module does not correspond to the latest series production configuration. The communication module software will be updated to enable remote software updates on other control units in the future. Further contributions to product improvement and increases in robustness will also be implemented with this software update. The update is free of charge and will be carried out in the background. MBUSA will conduct an OTA service campaign. Remote software updates are automatically downloaded and installed in the customer’s vehicle free of charge without an additional workshop visit via the data link of the communication module. No customer letter will be mailed for this software update.
