Benefits of using an original oil sump pan

Using an original oil sump pan in the drivetrain offers a number of practical operational benefits:

• Factory fitment to the transmission housing and mounting system, which facilitates installation and eliminates the need for modifications.
• Proper internal shaping of the sump, promoting even oil distribution and correct operation of the lubrication system.
• Compatibility with the manufacturer's specified mounting points for accessories and service components.

For users, this means more predictable transmission behavior, and for workshops – more efficient service and a lower risk of post-installation issues.

Condition and service application

The presented oil sump pan comes from the used Mercedes parts group, which allows for economical repair of the drivetrain while maintaining the original design. This type of component is particularly useful in situations where mechanical damage to the sump has occurred (e.g., impact from underneath) or there are issues with maintaining a proper seal.

Replacing the oil sump pan is a standard service procedure when repairing the lower part of the transmission housing, performing sealing work, or during major automatic transmission overhauls.

Technical support and part selection

When selecting an oil sump pan for the automatic transmission in a Mercedes-Benz A W168, it is crucial to pay attention to compatibility with the specific transmission type and the vehicle's factory parameters. Original manufacturer markings and reference numbers facilitate clear identification and minimize the risk of installing an incorrect component.
