Aluminium Shift Paddles BMW E46 M3 SMG II
These extended length aluminium shift paddles make gear changing easier and give the interior a more sporty and modern look.
Clutch / Selection Solenoid Valve BMW E46 M3 SMG II
New clutch / selection solenoid valve for the E46 M3 SMG II. There are two of these flow-proportional solenoid valves on the hydraulic unit: one for clutch control and another one for gear selection. If one of these two valves fails, the SMG can no longer correctly open and close the clutch or shift gears.
Complete Hydraulic Unit BMW E46 M3 SMG II
The refurbishment of the SMG II hydraulic pump includes intensive cleaning to remove old hydraulic oil as well as the installation of the following new parts:
- New hydraulic pump electric motor (sold here separately)
- New temperature sensor (sold here separately)
Compression Spring BMW E46 M3 SMG II
A broken compression spring can cause problems with the gear selection or adaption process.
Control Unit M3 SMG II
The transmission control unit (ECU / TCU) is the main computer responsible for the control of the M3 SMG II.
Hydraulic Lines for Relocation Kit BMW E46 M3 SMG II
Time to solve your SMG problems once and for all! With the Relocation Kit you can relocate the SMG hydraulic unit – away from the engine to the passenger side's 'drug bin'.
This offer includes a set of 4 hydraulic lines with each 190cm length. The lines are made-in-Germany from braided stainless steel, fitted with the proper connections for plug & play installation. You can find the additional wiring harness extension here.
Hydraulic Pump Seal Kit BMW E46 M3 SMG II
- Seal kit for the hydraulic pump of the M3 SMG II
- Damaged or hardened seals may cause the pump to be unable to build up pressure
- Precisely fitting seals made of high-quality material
Hydraulic Unit Pump Motor BMW E46 M3 SMG II
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
No worry – here is a solution for these problems!
We provide a new motor for the pump as a solution for various problems with the BMW M3 SMG II. The motor meets highest expectations of quality and enables a sporty style of driving with frequent shifting. Of course, the motor comes with a 12 month warranty.
The old motor can be replaced by the new one “plug&play“. The replacement motor is already equipped with the required pins and can be directly connected to the original wiring harness. For removing the old motor, you may need a release tool.
Intake Manifold Clamps BMW E46 M3 SMG II
This set contains 6 clamps for the intake manifold of the S54 engine. To access the SMG hydraulic unit, the intake manifold must be removed. Unlike the original clamps, the parts we offer are made of a more resistant material and are reusable.
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. You can learn more here. This is a repair service (no purchase of a product). Our terms and conditions and the right of withdrawal for the order of services apply.
Pressure Sensor BMW E36 M3 SMG I
The pressure sensor is located on the hydraulic unit of the M3 SMG I and measures the pressure of the hydraulic fluid. Since the cables are fused with the original pressure sensor, our pressure sensor must be connected to the wiring harness by soldering or crimping.
Pressure Sensor BMW E46 M3 SMG II
The pressure sensor is located on the hydraulic unit of the M3 SMG II and measures the pressure of the hydraulic fluid.
Pump Relay BMW E46 M3 SMG II
The pump relay is responsible to turn on / off the hydraulic pump of the SMG system. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the clutch or change gears.
Pictures shown are for illustration purpose only. The relay supplied may have a different color.
Pump Reservoir Seal BMW E46 M3 SMG II
New seal for the hydraulic pump plastic reservoir. The seal meets the requirements for use in the SMG hydraulic system.
Repair Kit Valve Plugs BMW E46 M3 SMG II
- New plugs for M3 SMG II solenoid valves
- Including cable and pins
- Ready for assembly
Set Clutch Parts BMW E46 M3 SMG II
Set of clutch parts contains:
- Pressure plate
- Friction plate
- Release bearing
We sell only Sachs or LUK components, both are original supplier for BMW.
Solenoid Valve Seal Kit BMW E46 M3 SMG II
- Seal kit for the solenoid valves of M3 SMG II
- Includes seals for all four solenoid valves
- Solution to eliminate internal leaks
Temperature Sensor BMW E46 M3 SMG II
The temperature sensor is located on the hydraulic unit of the M3 SMG II and measures the temperature of the hydraulic fluid. Due to its location in a high temperature area, the sensors suffers often from damage and is a common problem.
Transmission Speed Sensor BMW E46 M3 SMG II
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the SMG control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
Wiring Harness for Relocation Kit BMW E46 M3 SMG II
Time to solve your SMG problems once and for all! With the Relocation Kit you can relocate the SMG hydraulic unit – away from the engine to the passenger side's 'drug bin'.
This offer includes a 170cm long wiring harness extension, equipped with the original plugs, automotive cables and conduit. The additional hydraulic hoses are available here.
