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.
TEMPERATURE RESISTANCE
OEM plastic tubes can become brittle with age and heat, often breaking during disassembly. RacingLine's billet aluminium tubes retain strength and dimensional stability, even at elevated temperatures.
HIGH-PRESSURE
OEM components were never designed with increased clutch pressure in mind. The RacingLine design is ideal for tuned and high-torque applications, as well as hard-working daily drivers.
PERMANENT FIX
It's a one-time upgrade that prevents repeat failures and protects critical internal components. avoiding future failures during servicing or gearbox disassembly. Fit them once, fit the best.
Precision engineered for
perfect performance.
CNC constructed from T6-6061 aircraft grade aluminium ensuring unrestricted oil transfer
Billet-milled to withstand high temperatures, increased clutch pressures and long-term hard use
Kit includes all required high-temperature, top quality Viton O-Rings
Anodized gloss black to protect in the harsh operating conditions
Why
upgrade?
While the DQ381 and DQ500 DSG gearboxes are renowned for their strength, the factory plastic oil transfer tubes represent a clear weak point within the oil circuit. Exposed to repeated heat cycles and, in many cases, increased clutch pressures from software upgrades, these plastic components can become brittle over time and are prone to cracking — particularly during routine gearbox work such as mechatronics replacement or differential upgrades.
Once damaged, oil pressure can drop instantly, compromising clutch cooling and placing the mechatronics at serious risk. The RacingLine Oil Tube Transmission Kit addresses this vulnerability permanently, replacing the original plastic tubes with precision-machined billet aluminium components designed to withstand heat, load and long-term use.
We strongly recommend fitting these when installing our DQ381 Mechatronics Board Replacement.
