Accumulator – Alfa Romeo 159 Spider Brera Selespeed
Accumulator – Alfa Romeo 159 Spider Brera Selespeed

The accumulator is responsible to store the pressure of the hydraulic 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 defect is that the gas leaks out of the cell, which causes the system to be unable to build up hydraulic pressure. In many of such cases, the pump appears to prime permanently.

We offer the brand new original Magneti Marelli spare part.

Clutch Sensor – Alfa Romeo 159 Spider Brera Selespeed
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.

EV0 Clutch Solenoid Valve – Alfa Romeo 159 Spider Brera Selespeed
EV0 Clutch Solenoid Valve – Alfa Romeo 159 Spider Brera Selespeed

The EV0 Solenoid Valve is responsible for the clutch actuation of the Selespeed system. A faulty EV0 can cause problems while engaging the clutch (for example shuttering) and in consequence the car refuses to change gears.

This is an original Magneti Marelli spare part.

Gear Sensor – Alfa Romeo 159 Spider Brera Selespeed
Gear Sensor – Alfa Romeo 159 Spider Brera Selespeed

The Selespeed gear sensors (potentiometers) are responsible to detect the current state of the gear engagement. There are two of these sensors installed on the Selespeed unit. A faulty sensor can prevent the car to engage gears or shift.

We sell an original spare part from Magneti Marelli.

Pump Motor – Alfa Romeo 159 / Spider Selespeed
Pump Motor – Alfa Romeo 159 / Spider Selespeed

The pump motor drives the gear pump, which generates the pressure for the Selespeed transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.

In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.

We sell an original, brand new Magneti Marelli spare part – the same part you would get from Alfa Romeo.

Transmission Speed Sensor – Alfa Romeo 159 Spider Brera Selespeed
Transmission Speed Sensor – Alfa Romeo 159 Spider Brera Selespeed

This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
