Solenoid Valve Seal Kit BMW E36 M3 SMG I

The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This diaphragm type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a membrane. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.

We offer a brand-new replacement accumulator.

New selection angle solenoid valve for the E36 M3 SMG I hydraulic unit. This proportional valve is responsible for gear selection. A broken valve can cause problems during shift operations.

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.
