0BH DQ500 Improved Front Cover Oil Seal

0BH DQ500 Front Cover Oil Seal

0BH DQ500 Front Cover Oil Seal is an improved sealing component designed for professional repair and rebuilding of the 0BH DQ500 7-speed DSG transmission. The seal is installed in the front cover area of the gearbox and helps maintain proper transmission fluid sealing around the clutch and front transmission section.

Professional transmission parts suppliers list a dedicated 0BH Front Cover Seal With Spring for the DQ500 gearbox, confirming that this sealing component can be supplied separately from the complete transmission front cover.

The product is suitable for DSG transmission repair shops, automatic gearbox rebuilders, clutch specialists, automotive parts wholesalers and professional transmission parts distributors.

Because you have not provided an OE number, this page should not claim a specific Volkswagen OE reference.

If the original product or packaging later shows a part number, we can add that number to the page separately.

Function of the DQ500 Front Cover Oil Seal

The main function of the front cover oil seal is to prevent transmission fluid from escaping through the front sealing area of the gearbox.

The DQ500 is a wet dual-clutch transmission, so transmission oil is important for several gearbox functions including:

• Lubrication
• Hydraulic control
• Clutch cooling
• Internal component protection
• Transmission temperature management

If the front sealing area loses its sealing performance, transmission fluid may leak into or around the clutch housing area.

A properly installed oil seal helps maintain transmission fluid containment and protects the surrounding transmission components.

Improved Front Cover Seal Design

This product is supplied as an improved front cover oil seal.

Some repair-market DQ500 seals are sold with an additional spring-supported sealing structure. Professional suppliers list an 0BH front cover seal specifically as a Front Cover Seal With Spring.

The purpose of this type of design is to provide a stable sealing lip around the rotating contact surface.

However, the exact construction of improved seals can vary between manufacturers.

For this reason, customers should compare the actual product photo, dimensions and sealing structure rather than assuming all “improved” DQ500 seals are identical.

Front Cover Seal and Complete Front Cover Are Different Parts

The oil seal should not be confused with the complete DQ500 front clutch cover.

A complete front clutch cover for the 0BH DQ500 is available separately in the market and may be referenced under numbers such as 0BH301205D. That component is a complete front cover, while the product on this page is the sealing component used in the front cover area.

This distinction is important when purchasing transmission parts.

If a customer needs only the oil seal, replacing the complete cover may not be necessary.

If the cover itself is damaged, distorted or has a worn sealing surface, technicians should inspect whether a complete front cover replacement is required.

When May the Front Cover Oil Seal Need Replacement?

The 0BH DQ500 Front Cover Oil Seal may require replacement when technicians find transmission fluid leakage from the front area of the gearbox.

Possible reasons for seal replacement include:

• Hardened sealing material
• Worn sealing lip
• Seal deformation
• Damage during gearbox disassembly
• Transmission overhaul
• Front cover repair
• Clutch-related gearbox service

However, a front transmission oil leak does not always mean the seal itself is the only problem.

Technicians should also inspect:

• Front cover condition
• Shaft sealing surface
• Clutch housing
• Transmission casing
• Bearing condition
• Surrounding seals

If the shaft or cover sealing surface is badly damaged, installing a new oil seal alone may not solve the leakage.

Professional Installation Recommended

Transmission oil seals require correct installation.

Before installing the new seal, technicians should inspect and clean the sealing surface carefully.

The installation area should be free from dirt, old seal material and metal debris.

The seal should be installed evenly to prevent:

• Lip damage
• Seal distortion
• Incorrect depth
• Uneven sealing contact

Suitable installation tools should be used whenever required.

Professional DQ500 front cover products are sometimes supplied with an installation protector specifically to reduce the risk of damaging the inner seal during assembly, highlighting how important correct seal installation is.

After installation, the gearbox should be checked for leakage.

For DQ500 Transmission Repair Workshops

This product is suitable for:

• DSG transmission repair shops
• Automatic gearbox rebuilders
• DQ500 specialists
• Clutch and transmission repair workshops
• Automotive parts wholesalers
• Transmission parts distributors

During DQ500 rebuilding, workshops often require several sealing and service components together.

These may include:

• Front cover oil seals
• Housing seals
• O-rings
• Oil pan seals
• Repair kits
• Filters
• Solenoid valves
• Differential components

Using the correct sealing parts can improve the reliability of the rebuilt transmission.

Check Compatibility Before Ordering

Before purchasing the 0BH DQ500 Front Cover Oil Seal, please compare the original seal carefully.

We recommend checking:

• Transmission code
• Original seal dimensions
• Outer diameter
• Inner diameter
• Seal thickness
• Spring design
• Front cover structure
• Original product photo

If an OE or manufacturer number is visible on the original seal or package, please provide it.

Do not select an oil seal only because another product is also described as “DQ500 front seal.”

Different designs and production versions may exist.
