Communication Module System Software
Update – No Mercedes Me Connect OTA

This is to notify you of the Service Campaign OTA update for the communication module software in 171,202 Model Year (“MY”)
2017-2021 C-Class, CLA, CLS, E-Class, GLC, GLE, GLS, AMG GT, S-Class, SL, and SLC (205, 117, 257, 213/238, 253, 166/292,
190/290, 217/222, 231, 172) vehicles. The vehicles will not be visible or flagged in VMI or EVA.

Background
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined
that in certain MY 2017-2021 C-Class, CLA, CLS, E-Class, GLC, GLE, GLS, AMG GT,
S-Class, SL, and SLC (205, 117, 257, 213/238, 253, 166/292, 190/290,
217/222, 231, 172) vehicles, the software of the communication module does not
correspond with the latest series production configuration. This free of charge
update includes quality-enhancing optimizations for the communication module to
improve the system stability and better availability of the Mercedes me services.
The update is downloaded and installed in the background. This process takes
approx. 15 minutes. During the installation, the system can be used without
restrictions. The new software will be active after the vehicle has been switched off.

Issue

What We’re Doing

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.
All customers will be mailed a letter informing them of this software update.

Parts

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