Purpose and function in the exhaust system

The Mercedes W167 W205 C213 C238 Particulate Filter Pressure Pipes SET is responsible for transporting the exhaust pressure signal from the DPF area to the differential sensor. Properly selected pipes are crucial for:

• accurate measurement of the pressure difference before and after the particulate filter,
• correct diagnosis of the DPF saturation level by the ECU,
• stable execution of filter regeneration procedures,
• reducing the risk of the engine entering limp mode due to incorrect readings.

In the case of leaks, kinks, or improper routing of the pipes, errors related to the exhaust system may occur, which is why using a complete, matched set is important from both a reliability and diagnostic point of view.

Set construction and benefits of use

The offered Mercedes W167 W205 C213 C238 Particulate Filter Pressure Pipes SET has been designed specifically for Mercedes vehicles, which ensures proper routing relative to engine accessories and exhaust system components. The set includes pressure pipes with appropriately selected diameter and shape, which minimizes the risk of:

• local overheating near hot parts of the exhaust system,
• mechanical damage resulting from contact with other components,
• pressure signal interference caused by a line that is too long or improperly routed.

Using the original pipe design allows for maintaining factory DPF operating parameters, which is particularly important in vehicles equipped with advanced emission control strategies.

Component condition and installation aspects

The set of pipes is offered as a used part, which allows for an economical repair of the exhaust system while maintaining the manufacturer's original specification. Before installation, a standard visual inspection for any signs of excessive wear, mechanical damage, and patency of the pressure channels is recommended.

In workshop practice, installing the set involves recreating the factory routing of the pipes between the particulate filter and the differential sensor. Proper positioning and securing in the original brackets reduces vibration, protects against chafing, and ensures a stable pressure reading across the full range of engine loads.

Selection by numbers and compatibility verification

Due to structural differences between individual engine and body versions of Mercedes, the selection of the Mercedes W167 W205 C213 C238 Particulate Filter Pressure Pipes SET should always be based on catalog numbers and vehicle documentation data. In case of doubt, it is worth using tools for verification by OEM numbers to avoid problems with matching the length and geometry of the pipes.
