The problem: 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
We provide a new motor for the pump as a solution for various problems with the BMW M3 SMG II. This item is not a universal motor with a coupling plate to adapt to the SMG block like others available on the market, this item is specially made for the E46 SMG II specifically. The motor meets the highest expectations of quality and enables a sporty style of driving with frequent shifting. Of course, the motor comes with a 12 month warranty.
SMG relay replacement is also recommended any time a motor/pump fails.
Our kit includes the following:
- Brand new SMG II pump motor
- Rowe full synthetic hydraulic fluid, 1 litre
- Temperature sensor for hydraulic fluid
This product suits E46 models fitted with the SMG II system.
