# Service bulletin NCU\-2023060002

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.

Mercedes\-Benz AG \(“MBAG”\), the manufacturer of Mercedes\-Benz, has determined that on certain Model Year \(“MY”\) 2022 – 2023 SL Roadster \(232 platform\) vehicles, a leak in the engine intake manifold may be erroneously detected and potentially cause the check engine Malfunction Indicator Lamp \(‘MIL’\) to illuminate. MBUSA will conduct an Emission Service Campaign. An authorized Mercedes\-Benz dealer will update the engine control unit software on the affected vehicles.
