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.
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.
Maintenance Kit – Audi S-tronic 0B5 DL501
The maintenance kit for the Audi S-tronic transmission includes all necessary gaskets, seals, o-rings, and other plastic and rubber components required for the repair or refurbishment of the transmission and its hydraulic controller. This comprehensive kit ensures that every essential part is available for effective maintenance, supporting the transmission’s performance and longevity.
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.
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.
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.
