Official summary

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain subject vehicles, the SCN coding in the Belt-driven Starter Alternator (BSA) control unit does not correspond to the latest production specifications. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will perform an SCN coding in the BSA control unit.

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.
