DL501 (0B5) DSG Oil Service Kit – Mannol Fluid, Internal & External Filters

Maintain smooth, reliable performance from your 7-speed DL501 (0B5) DSG gearbox with our complete oil service kit. Supplied with Mannol DSG transmission fluid, external filter with O-ring, and internal gearbox filter, this kit provides the essential components required for a thorough DSG service.

The DL501 is a high-performance wet clutch transmission, and regular servicing is critical to protect the clutch packs, hydraulic circuits and mechatronic unit.

What’s Included:

• Mannol DSG transmission fluid (suitable for DL501 / 0B5 applications)

• External DSG oil filter

• Replacement O-ring seal

• Internal gearbox filter

Why Service the DL501 (0B5)?

The DL501 relies on clean, high-quality fluid to lubricate and cool its dual clutch system while maintaining precise hydraulic control. Over time, contaminated or degraded oil can lead to:

• Harsh or delayed gear engagement

• Clutch judder

• Mechatronic faults

• Premature clutch and valve body wear

Replacing both the internal and external filters, along with fresh fluid, helps maintain correct oil flow, stable pressure and consistent shift performance.
