OEM BMW SMG II accumulator for BMW E46 M3 & CSL – 21532229716

Product description

The original BMW pressure accumulator (piston accumulator) is a central component of the SMG II hydraulic unit and provides the necessary hydraulic pressure for gear shifts to be executed quickly and reliably.

The pressure accumulator is a typical wear part of the SMG II system. As it ages, the pre-charge pressure of the nitrogen filling drops, which means hydraulic pressure can no longer be stored sufficiently. This can result in the hydraulic pump running frequently, delayed gear shifts, or SMG system malfunctions.

With this original BMW pressure accumulator, you restore the full performance of your SMG II hydraulic unit and ensure reliable gearbox operation.
