Clutch Solenoid Valve – Audi S-tronic 0B5 DL501
Two clutch solenoid valves are used in the Audi S-tronic dual-clutch transmission, one for each clutch circuit. They control the hydraulic pressure required to engage and disengage the clutches, ensuring smooth and precise shifting. A defective valve can cause symptoms such as rough gear changes, delayed engagement, clutch slippage, or loss of drive in one gear set. We supply original clutch solenoid valves from BorgWarner – exactly the same parts that are installed in the transmission during vehicle production.
Drive Position Sensor – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
The drive position sensor (G676) is used in the Audi S-Tronic transmission to determine the position of the parking lock. If “P-ON” is detected, the selector lever sensor system control module (J587) activates the parking lock solenoid (N486), ensuring that the parking lock cannot be disengaged unintentionally. A malfunctioning drive position sensor may lead to issues with engaging or releasing the Park position properly.
Dual Clutch – Audi S-tronic 0B5 DL501
The dual clutch in the Audi S-tronic transmission uses two wet multi-plate clutches with alternating friction discs and steel lamellae to independently engage odd and even gear sets, enabling rapid gear shifts with uninterrupted power delivery. This is a brand-new clutch, supplied by the original equipment manufacturer – exactly the same parts installed in the transmission at the factory.
Gear Selector – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
The gear selector is a hydraulic actuator equipped with multiple pistons that are controlled by solenoid valves to move the shift forks within the transmission and engage the gears. In addition, the unit includes four gear selector position sensors and a transmission input speed sensor. These sensors continuously monitor the position of the shift forks and the rotational speed of both transmission input shafts, enabling precise gear engagement and real-time clutch control. This makes the gear selector one of the most critical components for shift operations within the transmission. A failure of the hydraulic actuator or its sensors can lead to gear selection issues or clutch malfunction. We offer a brand-new OE part from the same manufacturer that supplies mechatronic transmission components to Audi.

It is particularly suitable for users who are unable to identify the exact cause of their transmission issue or prefer not to troubleshoot individual faulty components. Delivered fully assembled, it ensures precise and reliable restoration of transmission functionality.
Many sellers offer used units that have been removed from a transmission and cosmetically refurbished. We strongly advise against such offers, as it is nearly impossible to properly test all the electronic components on these units. We offer a brand-new original replacement part in its original packaging.
Multi-Plate Clutch – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
The clutch pack of the S-tronic transmission is among the major weak points of this system and is known for premature wear. The system uses two wet multi-plate clutches that are exposed to high thermal and mechanical loads during continuous operation. Thermal overload, insufficient pressure regulation, and constant slipping at low speeds lead to worn separator plates, heat-damaged clutch packs, and inconsistent clutch behavior. This manifests as juddering during take-off, slipping under load, and erratic shifting, especially in stop-and-go traffic. We offer a brand-new, original BorgWarner replacement part – the same part that is factory-installed in the transmission and distributed directly by Audi.
Oil Filter Kit – Audi S-tronic 0B5 DL501
This oil filter kit is for performing a transmission service on the Audi S-tronic gearbox. It contains the transmission oil filter, oil strainer, and oil pan seal. The kit provides the necessary components for a fluid and filter change as part of regular maintenance.
Oil Filter Kit – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
This oil filter kit is for performing a transmission service on the Audi S-tronic transmission. It contains all three filters and housings mounted on the mechatronic unit. Especially with the 2nd generation S-tronic transmission, replacing all three filters is extremely important. For unclear reasons, Audi’s maintenance procedure does not include a filter change during an oil service, which results in many transmissions being operated with heavily clogged and contaminated filters. We recommend replacing the filters every time the hydraulic oil is changed.
Pressure Accumulator – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
The pressure accumulator is a crucial component of the Audi S-tronic transmission, responsible for storing hydraulic pressure to ensure smooth and rapid gear changes. A defective pressure accumulator can lead to delayed gear shifts, irregular transmission behavior, or error messages in the vehicle’s diagnostic system. We offer an original, unused OEM part that has been removed from a brand-new transmission. Please mind that due to the nature of the disassembly process and the metal surface, the part may show minor handling marks and can develop light surface rust.
Pressure Control & Clutch Cooling Valve – Audi S-tronic 0B5 DL501
This solenoid valve is used twice in the Audi S-tronic transmission, serving as the line pressure control valve (N472) and the clutch cooling valve (N471). N472 regulates the main hydraulic pressure, ensuring smooth gear shifts and proper clutch engagement. N471 controls the flow of cooling oil to the dual clutch, helping to maintain safe operating temperatures, especially under high load. A malfunction of N472 may lead to hard or delayed shifts, poor drivability, or activation of limp mode. If N471 fails, the clutch can overheat, triggering protective functions and reducing performance. Both valves are essential for the reliable operation of the transmission. We supply original solenoid valves from BorgWarner – exactly the same parts that are installed in the transmission during vehicle production.
Pressure Sensor – Audi S-tronic 0B5 DL501
Two of these sensors are installed in the Audi S-tronic transmission to measure the hydraulic pressure at the clutches.
Pressure Sensor – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
This sensor is used in the Audi S-tronic transmission to measure hydraulic pressure at the clutches; two are installed per gearbox (G545 and G546). It sends real-time pressure data to the transmission control unit to ensure smooth gear shifts and optimal clutch operation. If the sensor is faulty, symptoms may include harsh or delayed shifting, gear slipping, warning lights, stored fault codes, or activation of limp mode.
Printed Circuit Boards – Audi S-tronic 0B5 DL501
The printed circuit boards (PCB) are crucial components of the S-tronic transmission and are directly connected with the transmission control module (TCM). Various sensors are mounted on these boards, including the gearbox input shaft sensor and gear sensor. A defective PCB can cause various issues in the vehicle’s transmission system, including implausible signals from the engine control unit and electrical faults in multiple solenoid valves across different sub-transmissions. Additionally, problems can arise with the main pressure valve, cooling oil valve, and clutch temperature monitoring system, potentially leading to torque limitations due to high clutch temperatures. These electrical malfunctions can significantly affect the overall performance and reliability of the transmission system.
Pump Motor – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
This electric motor drives the gear pump of the mechatronic unit in the Audi S-Tronic transmission and is therefore directly responsible for generating hydraulic pressure. The hydraulic pressure is needed to control the clutches and gear actuators.
This part often fails due to improper installation and incorrect procedures during transmission work. If the mechatronic unit is connected to the vehicle’s electrical system before it is filled with oil, the pump motor may begin running continuously. As a result, the pump can overheat quickly, leading to damage to the electric motor and potentially to the gear pump as well. It is therefore crucial to follow the official procedures from the Audi workshop manual precisely and to set the vehicle into the appropriate service mode when working on the mechatronic unit. A defective pump motor will lead to a complete transmission failure.
Solenoid Valve Kit – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
