Official summary
Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz, has determined that on certain MY19-20 C-Class, GLC-Class, and AMG GT (205, 253, and 290 platform) vehicles, the software for the AMG drive unit control unit does not correspond to the current series production configuration. As a result, noise may occur from the engine mounts. An authorized Mercedes-Benz dealer will update the software as necessary.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
