Product Title: E46 M3 SMG II Electric Motor (New) with Service Kit
Boost the performance of your BMW E46 M3 SMG II pump with our reengineered electric motor. This advanced motor has been meticulously crafted to deliver a 20% performance improvement over the OEM motor, offering optimal operational efficiency for your vehicle.
One of the standout features of this upgraded motor is the integrated machined aluminum heat sink. This component effectively regulates the temperature of your system during prolonged use, whether you’re on the open road or pushing your vehicle’s limits on the racetrack. This feature alleviates the concern of overheating for continuous optimal performance.
This electric motor is specifically designed to handle the high torque of 90bar (1300 PSI) pressure requirements inherent in SMG duty cycles. This addresses the primary cause of SMG pump failures, motor malfunction, and system pressure loss, thus enhancing the longevity of your pump.
The E46 M3 SMG II pump motor kit includes the following components: A high torque DC motor, a drive coupler, a pin extractor tool, two installation screws, a sealing gasket, a grease packet, an SMG temp sensor, and a liter of CHF-11S hydraulic fluid. Also included are an SMG salmon relay and a 40amp SMG, both of which should be replaced if there has been a previous motor failure to prevent erratic pump switching times and potential damage to new components.
The kit comes with a one-year warranty, under which it is mandatory to replace the salmon relay and 40amp fuse. This product corresponds to several part numbers, including 21-53-2-282-257, 21-53-2-282-364, 21532229715, 21532282257, 21532282364, and 31212634120. It also addresses DME error codes related to the unit, such as 56 (0x38), 53 (0x35), 57 (0x39), and 55 (0x37).
