21532229092 Pressure Accumulator suits BMW E36 M3, E36 M3 3.2

The pressure accumulator plays a crucial role in hydraulic systems by storing system pressure for later use by the actuators. This diaphragm-type accumulator consists of two chambers: one for hydraulic fluid storage and another filled with nitrogen gas, which provides the counter pressure. A flexible membrane separates these two chambers.

Common indicators of a failing pressure accumulator include frequent, short pump cycles. When the accumulator loses its preload pressure, the pump may engage every few seconds, eventually causing damage to the pump motor. Alongside pump motor failure, a worn pressure accumulator is a leading cause of pressure build-up issues. It is also one of the few consumable parts in the system that requires regular inspection and timely replacement.
