Purpose and function in the M272 engine

The presented item belongs to the Oil drain and filler plugs and dipsticks category and is responsible for guiding the dipstick in the M272 engine, used in vehicles such as the Mercedes W203, W204, W209, and W212. The guide tube ensures stable seating of the dipstick, reduces the risk of contamination, and facilitates quick oil level checks during periodic maintenance or diagnostics. By maintaining the original mounting geometry, this solution is perfectly matched to the factory lubrication system, which promotes trouble-free operation.

Benefits of using an original guide tube

Using an original oil dipstick with a guide tube in the M272 engine allows for maintaining engine performance parameters in accordance with the manufacturer's design. Key advantages include:

• secure dipstick guidance and repeatable oil level readings,
• preservation of factory sealing at the dipstick insertion point,
• compatibility with engine accessories specific to the M272 series,
• reduction of the risk of incorrect oil level interpretation during service.

For users and workshops, this means stable, predictable lubrication system maintenance and a lower risk of issues resulting from ill-fitting aftermarket replacements.

Condition, origin, and service application

The component comes from the Mercedes brand, which translates to compatibility with factory mounting points and the routing of the tube within the engine bay. This used product is a good choice for maintenance repairs when the original guide tube has suffered mechanical damage, corrosion, or deformation during previous service work. Replacing it with an original component allows for restoring the correct dipstick path and comfortable operation during every oil level check.

Part selection and mounting compatibility

The guide tube with dipstick is identified by its OEM part number and related interchangeable numbers, which facilitates precise matching to a specific version of the M272 engine. When selecting, it is recommended to verify the part using the VIN or service documentation to ensure full compatibility with the installed equipment configuration. This approach minimizes the risk of installation problems and helps maintain the integrity of the entire lubrication system.
