Hydraulic Unit Pump Motor BMW E46 M3 SMG II
[tabs] [tab title="The problem" start=open] The pump supplies the hydraulic pressure for the different consumers (actuators) of the SMG and stores it in the pressure accumulator. The pump consists of a gear pump and the powering electric motor. Due to its location in a high temperature area, the motor suffers often from damage and is a common problem. Especially on hot days the car can drop out of gear or show the gearbox warning light (SMG cog light). Often the following codes appear in the error memory:
- 56 (0x38) Switching-on time of hydraulic unit
- 53 (0x35) low level of pressure reached HE
- 57 (0x39) Misuse of hydraulic unit
- 55 (0x37) Switching-on frequency of hydraulic unit

Pressure accumulator BMW E46 M3 SMG II
Our refurbished pressure accumulators are equipped with a filling valve and freshly filled with nitrogen gas.The accumulator is responsible to store the pressure of the SMG system for later access by the actuators. The piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a moving piston. A broken accumulator causes the pump to prime permanently.Important: You will need to pay a core charge (deposit) of 300,00€ which will be refunded when you return your used part.
