Pressure Sensor 5-speed SMG
incl. 19% VAT plus Shipping Costs
The pressure sensor measures the hydraulic pressure in the accumulator. Based on this value, the SMG enables and disables the hydraulic pump to fill up pressure. This is a brand-new original part.
- Condition: New
- Compatible vehicles: BMW E46
Pentosin CHF 11S
Pentosin CHF 11S is a synthetic high performance hydraulic fluid for life-time application in modern vehicle aggregates. Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.
It is suitable for all extreme conditions and guarantees full performance from -40 Degree Celsius to over 130 Degree Celsius system temperature.
Pentosin CHF 11S meets DIN 51 524T3 and ISO 7308 specification standards.
Pump Motor 5-speed SMG
The pump motor drives the gear pump, which generates the pressure for the SMG 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 BMW.
Pressure Accumulator 5-speed SMG
Our refurbished pressure accumulators are equipped with a filling valve and freshly filled with new nitrogen gas.
The accumulator is responsible to store the pressure of the SMG system for later access by the actuators. The piston 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 moving piston. A broken accumulator causes the pump to prime permanently.
Important: You will need to pay a core charge (deposit) of 300,00€ which will be refunded when you return your used part. You can learn more here. This is a repair service (no purchase of a product). Our terms and conditions and the right of withdrawal for the order of services apply.
Control Unit 5-speed SMG
The transmission control unit (ECU / TCU) is the main computer responsible for the control of the 5-speed SMG.
Please mind: The product photo is for illustrative purposes only. Please ask us which specific part number we have in stock before purchase. There are various part numbers of this ECU, some of which are compatible with each other. Some ECUs need to be coded or flashed after installation. Checking the compatibility is your responsibility, a return is not possible.
