BMW E70 E71 Oil Sump Pan Cover Flap Protection Reinforcement Plate 7173468

BMW E70 E71 Oil Sump Pan Cover Flap Protection Reinforcement Plate is an original structural component designed for the rear section of the lubrication system in BMW E70 and E71 series vehicles. This robust protective plate acts as a cover and reinforcement, stabilizing the oil sump area and protecting critical components from mechanical damage. Thanks to the factory BMW design, it ensures precise fitment and predictable component behavior during operation.

Purpose and function of the component

The cover – reinforcement protection plate, which is part of the Oil sumps group, is responsible for stiffening the rear part of the sump assembly and protecting the lubrication zone from external factors. Its placement in the rear of the vehicle allows for:

• increasing structural rigidity in the oil sump area,
• reducing the risk of mechanical damage from the road surface,
• stabilizing the operation of components interacting with the lubrication system.

As a result, the oil system maintains proper operating conditions, and chassis loads are better distributed across the load-bearing structure.

Compatibility with BMW E70 and E71

The component was designed specifically for the BMW E70 and E71 platforms, meaning that the geometry, mounting points, and shape are adapted to the factory structural solutions of these models. The original BMW part ensures:

• secure fitment with factory mounting points,
• maintenance of the manufacturer-intended rigidity of the rear part of the system,
• no need for modifications or adjustments during installation.

Such fitment is particularly important in vehicles with higher mass and a higher center of gravity, where chassis structural stability has a direct impact on the durability of the lubrication system.

Characteristics of the used OEM component

The offered reinforcement protection plate is a used part, sourced from dismantling, which allows for maintaining factory build quality while reducing service costs. The original BMW component is distinguished by:

• material thickness and shape designed for the specific model,
• factory mounting points ensuring stable attachment,
• compatibility with other oil sump system components in the rear of the vehicle.

Choosing an original, used protection plate is a technically safe solution that allows for maintaining structural consistency with the manufacturer's specifications.

Benefits of installing the reinforcement protection plate

Using this cover – protection plate in a BMW E70 or E71 provides a number of practical operational benefits:

• Better protection of the lubrication system – reducing the risk of oil sump damage from the road surface and contaminants.
• Reinforcement of the rear chassis zone – improving load distribution in the oil sump area, which promotes the durability of interacting components.
• Factory fitment – maintaining original geometry and ground clearance without interfering with the vehicle's structure.
• Economic repair – the ability to restore proper oil system protection without the need to purchase a new part.

Application in service and upgrades

The cover – reinforcement protection plate is suitable both for standard repairs following mechanical damage and for restoring the completeness of covers in the rear oil sump zone. This is particularly important in vehicles operated in more demanding road conditions, where the lubrication system is exposed to more frequent contact with contaminants and impacts from the ground.

If you are planning a comprehensive repair or upgrade of the engine area in your BMW and need other components from the same group, such as additional sump covers, reinforcement covers, or protection plates, check the available parts in the BMW Oil sumps category.
