Racingline DSG Gearbox Billet Oil Feed Tubes for DQ500/DQ381

Racingline DSG Gearbox Billet Oil Feed Tubes for DQ500/DQ381

The Racingline Billet Oil Feed Tubes are a direct replacement for the factory plastic oil transfer tubes found inside the DQ381 and DQ500 DSG gearboxes used across the Volkswagen Group range. The original plastic items are a well-known weak point: heat cycles, age, and the added stress of tuned engines can cause them to become brittle, crack, or snap entirely – often during routine servicing such as a mechatronics or clutch replacement.

As an authorised Racingline retailer, we recommend these tubes as a sensible, preventative upgrade for any owner running a DQ381 or DQ500 gearbox, whether the car is standard, tuned, or used regularly on track.

Why Replace the Factory Plastic Tubes?

The oil feed tubes carry transmission fluid to critical areas of the gearbox, including the clutch packs and mechatronic unit. If a plastic tube fails, oil pressure drops, which can lead to poor shifting, clutch slip, and in worst cases internal gearbox damage. Replacing them with a billet alternative removes that risk entirely.

• CNC-machined billet aluminium construction for long-term durability
• Maintains consistent oil flow and pressure to the clutches and mechatronics
• Resistant to heat cycling and the higher torque loads of tuned engines
• Ideal upgrade during scheduled clutch or mechatronics servicing
• Direct replacement – no modification required

When to Fit Them

The most practical time to install these tubes is during any major gearbox service, such as a DSG clutch refresh, mechatronics replacement, or gearbox rebuild. Fitting them at this stage avoids the cost of opening the gearbox again later and removes the chance of the brittle plastic originals failing during disassembly.

Important: These tubes should be fitted by a qualified technician familiar with DSG gearbox servicing. Correct installation and the use of fresh DSG fluid are essential to ensure reliable operation.

Summary

If you own a DQ381 or DQ500-equipped VW, Audi, Skoda or SEAT, replacing the factory plastic oil feed tubes with the Racingline billet version is one of the most cost-effective ways to protect your gearbox. It is a small part with a big role – and one that is well worth upgrading before the original lets you down.
