# Service bulletin NCU \- 2024020005

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

This is to notify you of the Service Campaign Launch to update the SCN coding for the drive unit DRVU Control Unit in 66,944 Model Year \(MY\) 2023 C\-Class, GLC, S\-Class, and SL \(206, 223, 232, and 254 platform\) vehicles. The vehicles will be visible and flagged in VMI as OPEN on April 5, 2024. Mercedes\-Benz AG, the manufacturer of Mercedes\-Benz vehicles, has determined that on certain MY 2023 C\-Class, GLC, S\-Class, and SL \(206, 223, 232, and 254 platform\) vehicles, the DRVU control unit does not correspond to current production specifications. As a result, an incorrect fault stored message may appear \(e.g. U188D00 and U015400\) in the instrument cluster, indicating a missing signal, when in fact such signal is not required at this time. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the SCN coding for the DRVU Control Unit.
