The Mercedes W169 W245 M266 oil dipstick tube is an original lubrication system component designed for M266 series gasoline engines in A-Class and B-Class models. As part of the hoses, pipes, and tubes group, it is responsible for correctly guiding the dipstick and providing convenient, controlled access to the oil level. A used OEM component is a sensible choice for engine servicing when structural fit and long-term stable operation are important.

Purpose and Function in the M266 Engine
The oil dipstick tube in the M266 gasoline engine guides the dipstick from the engine block to the upper part of the engine bay, ensuring convenient access when checking the oil level. A correctly selected component:
- maintains the stable position of the dipstick relative to the oil pan,
- minimizes the risk of leaks at the point of insertion into the block,
- ensures a repeatable oil level reading during every service check.
This makes engine unit servicing predictable, and oil level diagnostics proceed in a repeatable and safe manner for the gasoline engine.
Design and Fitment for Mercedes W169 / W245
The oil dipstick tube in this version is specifically designed for the engine bay architecture of Mercedes A-Class (W169) and B-Class (W245) with the M266 unit. This means:
- geometry adapted to the factory engine equipment,
- proper routing in the engine bay, without interference with other hoses and components,
- factory mounting points, facilitating installation and stable securing.
Such a fit limits the risk of stress, vibrations, and accidental dipstick dislodgement, which is important for the durability of the entire lubrication system.
Benefits of Using an Original Oil Dipstick Tube
Using an original oil dipstick tube in a gasoline engine offers a range of practical operational benefits:
- Precise Oil Level Check – the correct position of the dipstick relative to the oil pan allows for a reliable reading, making it easier to maintain the proper lubrication level.
- Compatibility with Factory Equipment – no need for modifications, adjustments, or alterations to other components in the engine bay.
- Stable Mounting – appropriately designed brackets and tube shape reduce vibrations, contributing to the element's longer lifespan.
For drivers who regularly service their car, a functional oil dipstick tube is an important element of preventative maintenance against excessive engine wear.
Product Characteristics and Condition
The offered oil dipstick tube belongs to the hoses, pipes, and tubes category, highlighting its role as a guiding and structural element within the engine. The product is from a dismantled vehicle, thus retaining its factory fit for the M266 unit and the installation layout in Mercedes W169 and W245. A used OEM component is a practical solution for repairs where assembly compatibility and maintaining the original dipstick routing geometry are priorities.
Selection and Installation of the Oil Dipstick Tube
When selecting an oil dipstick tube for a Mercedes A-Class or B-Class with an M266 gasoline engine, matching it to the specific engine version and body type is crucial. In practice, this means:
- verifying compatibility with the engine type,
- checking the engine bay equipment configuration,
- inspecting mounting points and the method of seating in the block.
Installation typically does not require specialized modifications – after correctly seating it in the block's socket and securing it to the designated brackets, the tube is ready to work with the oil dipstick. After installation, it is advisable to perform a leak check around the socket and verify that the dipstick moves freely throughout its range.
