Service bulletin SC-2019020002

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.

NCU-HU SW Update2023-09-01. Service bulletin. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2018-2023 C-Class, EQE, EQE SUV, EQS, EQS SUV, GLC, GLE and S-Class (206, 295, 294, 297, 296, 254, 167 and 223 platform) vehicles, the communication module software does not correspond with the latest series production configuration. The update is free of charge and will be carried out in the background. The installation will eliminate software errors for a better entertainment experience. The update will show after the ignition has been cycled. MBUSA will conduct an OTA service campaign. A workshop visit for the customer is not required since remote software updates are automatically downloaded and installed in the customer’s vehicle. The OTA may be validated as successful on the customer’s Mercedes Me connect app under “Over-the-Air Vehicle Updates” as “Update for the communication module”. If the OTA is successful it will show a green “installed” and date of installation in the Over-the-Air update section.
