Clutch Valve – Audi R8 R-Tronic
The clutch solenoid valve (marked with ‘QPV’) is responsible for actuating the clutch in the R-Tronic system. A faulty valve can cause problems with clutch engagement, such as shuddering, delayed and harsh engagement, or even a complete failure of clutch actuation.

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.

On/Off Valve – Audi R8 R-Tronic
The selection solenoid valve (marked ‘OOV’) is responsible for moving the gear selector sideways to select gear pairs. If this two-way on/off valve fails, the car may be unable to engage one or more gears. Note: the product photo is for illustrative purposes only, the valve is supplied without the Magneti Marelli sticker.

Pressure Sensor – Audi R8 R-Tronic
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the R-Tronic system. This is an original and brandnew spare part.

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.
