Pressure sensor 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
