Official summary

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY21-23 C-Class and S-Class vehicles (206, 223 platform), the software for the ISA control unit may not correspond with the latest series production configuration. The possibility exists that the function of the ISA may not be restricted with an active Malfunction Indicator Lamp. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the ISA control unit software in the affected vehicles.

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.
