Reservoir Filler Plug BMW E60 M5 E63 M6 SMG III

This set includes all 8 piston seals for the selector rods located on top of the gearbox. The seals are made from a higher quality and more durable material than the original ones.

The temperature sensor is located on the hydraulic unit of the M5 / M6 SMG III 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.

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.

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.
