This is to notify you of the Over-The-Air (“OTA”) Service Campaign for the communication module software for Mercedes Me

463 platform) vehicles. The vehicles will not be visible or flagged in VMI or EVA.

Background
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.
Parts are not required for repair. Remedy software will be pushed via OTA.
