RacingLine DSG Billet Oil Gearbox Feed Tubes for DQ500 / DQ381

What the DSG Oil Feed Tubes do.

Volkswagen Group’s DQ381 and DQ500 DSG gearboxes rely on a series of internal plastic oil transfer tubes to route pressurised oil between the clutch housing, pump and gearbox casing – a design that becomes increasingly vulnerable with heat cycles, age and higher torque levels.

• So the RacingLine Oil Tube Transmission Kit replaces these failure-prone plastic components with precision CNC-machined billet aluminium tubes, delivering a permanent, leak-free solution designed to withstand high temperatures, increased clutch pressures and long-term use — whether on a standard vehicle or a heavily tuned application.
• During routine work on the gearbox such as mechatronics replacement, clutch servicing or differential upgrades, these factory plastic tubes commonly crack or split on removal, risking oil pressure loss and serious internal damage.
• This is the ideal time to install the DSG Oil Feed Tubes. They will ensure future-proof reliability however hard your car is driven, preventing repeat failures – especially during servicing or gearbox disassembly.
• More importantly, they will maintain consistent oil pressure and flow, critical for clutch cooling and mechatronics reliability. This makes them a crucial upgrade for high-torque applications, ideal for tuned vehicles where clutch pressures are increased and cars used hard on track, where heat-soak will lead to failures of the plastic OEM parts.
