The Vemo V30-72-0011 Air Mass Sensor is a high‑precision component designed to measure the amount of air entering an internal combustion engine. It delivers accurate airflow data to the vehicle’s Engine Control Unit (ECU), enabling optimal fuel injection, ignition timing, and emissions control.

Key Features

• High Accuracy: Provides precise mass‑air flow readings across a wide range of operating conditions.
• Robust Construction: Built with durable materials to withstand harsh automotive environments, including temperature extremes and vibration.
• Compact Design: Fits seamlessly into the existing intake manifold layout without requiring major modifications.
• Low Power Consumption: Operates efficiently, reducing electrical load on the vehicle’s battery system.
• Long‑Term Reliability: Engineered for extended service life with minimal drift over time.

Technical Specifications

Compatibility Overview

The Vemo V30-72-0011 is engineered to match the intake manifold geometry and electrical interface of a wide range of Mercedes-Benz models, including:

• C‑Class (W202, W203)
• CLK (C207)
• E‑Class (E200, E250, etc.)
• M‑Class (M240, M260, etc.)

Its standardized connector and mounting flange allow for straightforward replacement of OEM sensors without the need for custom adapters.

Installation Guide

1. Preparation: Disconnect the vehicle’s battery to prevent electrical shock. Remove any protective covers from the intake manifold.
2. Remove Old Sensor: Unscrew the existing mass air flow sensor using a suitable socket set. Carefully detach the electrical connector, noting the pin orientation.
3. Install New Sensor: Align the Vemo V30-72-0011 with the mounting flange and secure it with the provided fasteners. Reconnect the 5‑pin connector, ensuring each pin is seated correctly.
4. Check for Leaks: Inspect the intake manifold for any air leaks around the sensor area. Tighten as necessary.
5. Reboot ECU: Reconnect the battery and start the engine. Allow the ECU to perform its self‑diagnosis; a successful readout indicates proper installation.

Maintenance & Troubleshooting

• Regular Inspection: Periodically check for signs of wear or contamination on the sensor element. Clean with manufacturer‑approved solvents if necessary.
• Signal Verification: Use a diagnostic scan tool to confirm that the airflow signal remains within expected parameters during idle and acceleration.
• Common Issues:
  • Erratic Engine Performance: May indicate sensor drift or electrical noise. Verify connector integrity and grounding.
  • Check Engine Light (CEL): A faulty MAF can trigger CEL codes such as P0101–P0104. Reset the code after replacement.
• Replacement Interval: While designed for longevity, recommend sensor inspection every 60,000 km or when performance anomalies arise.
