Accumulator – Audi R8 R-Tronic
Accumulator – Audi R8 R-Tronic

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 valve – Audi R8 R-Tronic
Clutch valve – Audi R8 R-Tronic

The clutch solenoid valve (marked with “QPV”) is responsible for the clutch actuation of the R-Tronic system. A faulty valve can cause problems while engaging the clutch (for example shuttering) and in consequence the car refuses to change gears.

This is an original and new Magneti Marelli spare part.

Gear sensor – Audi R8 R-Tronic
Gear sensor – Audi R8 R-Tronic

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

We sell an original spare part from Magneti Marelli.

Pump motor – Audi R8 R-Tronic
Pump motor – Audi R8 R-Tronic

The pump supplies the hydraulic pressure for the different consumers (actuators) of the Audi R-Tronic transmission 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 Audi is a vulnerability and likely to fail due to its location in a high temperature area.

Our motor comes directly from the original equipment manufacturer (OEM) for Audi. 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.

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.

Shift valve – Audi R8 R-Tronic
Shift valve – Audi R8 R-Tronic

The shift solenoid valves (marked with “PPV”) are responsible for changing the gears of the R-Tronic system. There are two of these valves on the actuator. Together with the on/off valve, they operate the shift actuator. If one of the valves is faulty, the car will refuse to go into one or more gears.

This is an original and new Magneti Marelli spare part.
