Bulletin Summary
Certain Maserati MC20 (M240) MC20 Cielo (M241) MY22 MY23 MY24 listed in MODISCS+ are involved in a Rapid Update to update the ECM (Engine Control Module) software. This new software enhances the sleep mode of the exhaust pipe flap valve actuator, preventing loss of communication with the active exhaust valve. In rare cases, the engine could enter limp mode, and the MIL light can only be turned off after three key cycles.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
