Some Mercedes-Benz C240 owners report experiencing persistent limp mode issues even after replacing the conductor plate. This can be attributed to potential valve body or conductor plate failures, which may render the transmission unable to exit limp mode despite the replacement. Additionally, electrical problems involving the Transmission Control Module (TCM) or related wiring can contribute to this ongoing issue. Sensor malfunctions, particularly with components like the rpm sensor (N2), may also lead to intermittent signal disruptions that keep the transmission in limp mode. Furthermore, some owners find that an incomplete reset of the transmission codes can prevent the system from returning to normal operation. To effectively address these concerns, thorough diagnostics of electrical components and sensors, along with a proper reset of codes, are crucial. If issues persist, consulting a qualified mechanic or technician is recommended to identify and resolve the underlying causes.
