Communication Module Software Update –
Mercedes Me Connect OTA
This is to notify you of the Service Campaign OTA to update the Communication Module Software for Mercedes Me Connect in
7,274 Model Year (“MY”) 2021 S-Class (223 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 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.
Issue
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.
Parts are not required since the remedy software will be pushed via OTA.
