Accumulator – Alfa Romeo 159 Spider Brera Selespeed
The accumulator is responsible to store the pressure of the Alfa Romeo Selespeed system for later access by the actuators. The bladder 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 membrane. These accumulators have a certain life span and a common fail is that the gas leaks out of it's cell which makes the system unable to store pressure. In a lot of such cases, the pump appears to prime permanently. We offer the brand new OEM part.
Clutch sensor – Alfa Romeo 159 Spider Brera Selespeed
The Selespeed clutch sensor (potentiometer) is responsible to detect the current state of the clutch engagement. This sensor is mounted on the clutch slave cylinder. A faulty sensor can prevent the car to open or close the clutch. We sell an original spare part from Magneti Marelli.
Gear sensor – Alfa Romeo 159 Spider Brera Selespeed

Pump motor – Alfa Romeo 159 / Spider Selespeed
[tabs] [tab title="The problem" start=open] The pump supplies the hydraulic pressure for the different consumers (actuators) of the Selespeed and stores it in the pressure accumulator. The pump consists of a small gear pump and the powering electric motor. Depending on the year of construction, the electric motor used by Alfa Romeo is a vulnerability and likely to fail due to its location in a high temperature area. [/tab] [tab title="Our motor"] Our motor comes directly from the original equipment manufacturer (OEM) of the Selespeed system. Various car manufacturers purchase their parts directly from this supplier. The motor meets highest expectations of quality and enables a sporty style of driving with frequent shifting. [/tab] [tab title="Installation"] The motor can be changed easily as it is only attached by two screws to the pump head. It is not necessary to remove the entire pump but however sometimes helpful.
