Mercedes W203 W209 Diesel OM611 Air Flow Mass Meter Sensor Pipe A2035200095

Mercedes W203 W209 Diesel OM611 Air Flow Mass Meter Sensor Pipe is an intake system component designed for diesel engines, responsible for stable airflow to the power unit. By maintaining the factory geometry and cross-sectional diameter, it ensures proper flow, which promotes efficient operation of the turbocharged diesel engine and correct interaction with sensors in the intake system. It is a practical solution for users who want to restore the original performance parameters of the air intake system in their Mercedes.

Purpose and role in the intake system

The described air hose operates in the engine air supply area and is part of the Air and fuel intake sensors group. Its task is to provide a tight and stable connection of intake components so that air reaches the engine in a controlled manner, without leaks or flow disturbances. This has a direct impact on the fuel dose, turbocharger operation, and correct readings from air pressure and temperature sensors.

In a diesel engine, such as the OM611, properly routed air is crucial for maintaining the appropriate torque, smooth operation, and reducing smoke emissions. Replacing a worn or damaged hose with a functional part allows for the elimination of problems such as power loss, rough idling, or errors stored in the engine control unit.

Compatibility and fit for Mercedes C W203

The pipe has been designed for use in the Mercedes C-Class W203 generation with the OM611 unit, which means its shape, connection diameters, and mounting points are adapted to the factory intake system. As a result, installation is straightforward, without the need for modifications or additional adapters.

The original origin from the Mercedes brand helps maintain compatibility with other system components – both mechanical and electronic. In practice, this translates into:

• secure fitment with the air filter housing and intake manifold,
• proper routing of the hose in the engine bay,
• preservation of factory support points and mounts.

Technical characteristics and functional group

The element belongs to the Air and fuel intake sensors group, which highlights its importance for the proper functioning of the entire engine supply path. Although the hose itself is not a sensor, it works directly with them – it ensures stable flow conditions, making pressure and air temperature measurements repeatable and reliable.

The product is intended for units powered by Diesel, where pressures in the intake system are higher than in naturally aspirated engines. The proper stiffness and shape of the hose help reduce the risk of deformation under load, and thus maintain the appropriate airflow characteristics throughout the entire rev range.

Condition, origin, and practical benefits of installation

The offered element has a used status, which makes it a reasonable choice for drivers looking for an economical solution while maintaining the original specification. Choosing such a component allows you to:

• reduce repair costs compared to a new replacement,
• maintain the consistency of the intake system with factory solutions,
• minimize the risk of fitment issues and leaks.

For many users of Mercedes C W203 with the OM611 engine, using an original air hose is a way to restore stable operation of the power unit after the failure of an old part, cracking, abrasion, or seal leakage.

Part selection by numbers and technical support

The product has a dedicated OEM part number and assigned interchangeable numbers, which facilitates precise identification and selection for a specific vehicle configuration. It is worth comparing the markings with the data from the rating plate or the removed part to ensure full compatibility.
