Clutch Solenoid Valve BMW E60 M5 E63 M6 SMG III
The clutch solenoid valve is located next to the pump at the driver’s side of the gearbox and is responsible for the clutch actuation of the SMG system. A faulty valve can cause problems while engaging the clutch (for example shuttering) and in consequence the car refuses to change gears. This is a factory-new spare part.
Gear Position Sensor Repair Harness BMW E60 M5 E63 M6 SMG III
New wiring harness to repair the gear position sensor strip located on top of the gearbox. Roughened or frayed cables are a common problem with this wiring harness. When the insulation of the cables is broken, short circuits occur, which lead to various SMG malfunctions and error messages (for example 4F80, 4F82, 4F85). Our wiring harness repair kit is supplied with a ready-made original BMW connector.
Hydraulic Pump Internal Gears BMW E60 M5 E63 M6 SMG III
The internal gears of the hydraulic pump tend to wear mechanically and as a result the pump can no longer build up pressure. Our set includes new gears and metal seals that exactly match the original specifications and restore the function of the pump. In the process of overhauling the gear pump, we also recommend replacing the seals, which you can find here.
Pressure Accumulator BMW E60 M5 E63 M6 SMG III
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.

Pump Relay BMW E60 M5 E63 M6 SMG III
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 in your car may have a different color.
Transmission Speed Sensor BMW E60 M5 E63 M6 SMG III
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.
