Mercedes W205 W207 W212 Oil Sump Pan Level Sensor Holder A2740180701

Mercedes W205 W207 W212 Oil Sump Pan Level Sensor Holder is a precision mounting component designed for the lubrication system in selected C-Class, E-Class, and E-Class Coupé models. It is responsible for the stable and secure seating of the oil level sensor, which promotes reliable reading of engine operating parameters and reduces the risk of measurement errors. Thanks to the factory Mercedes design, the holder ensures proper guidance of the sensor in the oil sump area and compatibility with the original engine equipment.

Purpose and function in the lubrication system

The oil level sensor holder in Mercedes W205, W207, and W212 models plays a key role in the correct positioning of the measuring element relative to the oil level. Proper sensor alignment allows the engine control unit to correctly interpret the lubricant level, which is important for:

• maintaining a safe oil level in the engine,
• proper operation of engine monitoring systems,
• reducing the risk of false warnings about oil levels being too low or too high. By using an original holder from the Holders, mounts, and mounting parts category, compliance with the factory mounting geometry and the position of the sensor intended by the manufacturer is maintained.

Construction and fitment for Mercedes W205, W207, W212

The element has been designed specifically for the architecture of engines used in Mercedes W205, W207, and W212, which translates into:

• properly shaped mounting points for the engine block or oil sump,
• adherence to factory dimensional tolerances,
• compatibility with the original oil level sensor used in these models. Such fitment promotes trouble-free installation and minimizes the risk of stress, looseness, or misalignment of the sensor, which could affect the accuracy of the measurement or the durability of the entire assembly.

Characteristics of the used component

The offered holder comes from dismantling, which means it is an original Mercedes part with preserved mounting geometry. A used component of this type is particularly attractive in situations where:

• the existing holder has suffered mechanical damage (cracking, broken mounting lug),
• there are problems with the correct seating of the sensor after previous repairs,
• you are looking for an economical solution while maintaining the factory design. In the case of holders and mounts, stability and dimensional compliance are key, which is why using an original used part is often more predictable than installing a replacement of uncertain specification.

Benefits of using an original sensor holder

Replacing a damaged or deformed oil level sensor holder with an original Mercedes part brings a number of practical benefits:

• Stable sensor mounting – reduction of vibrations and shifts, which promotes measurement repeatability.
• Better cooperation with engine electronics – correct oil level data facilitates vehicle diagnostics and operation.
• Consistency with the factory design – no need for modifications, adjustments, or the use of additional washers.
• Reasonable repair cost – especially important when servicing several-year-old Mercedes W205, W207, and W212 models.

Mercedes holders and mounts – expansion and service

If you are planning a comprehensive repair or upgrade of the engine area in your Mercedes and need other elements from the same group, such as additional holders, cable mounts, or accessory brackets, check the available parts in the Mercedes holders, mounts, and mounting parts category.

More about the use of original parts from dismantling

When planning repairs and upgrades, it is worth knowing the broader context of using original components from the secondary market. See how such an approach works on the example of the styling package in the C-Class by reading the article Recycled Mercedes AMG Line package – original parts that will transform any C-Class (W204). This will make it easier for you to assess when used mounting elements are the optimal choice for your service project.
