Vehicle Compatibility

The sensor is specifically calibrated for the following Mercedes-Benz and Smart models:

• C280 (1997‑2000)
• C36 AMG (1997)
• C43 AMG (1998‑1999)
• E320 (1997‑2002)
• E430 (1998‑2002)
• E55 AMG (1999‑2002)
• ML320 (1998‑2003)

These models share a common crankshaft architecture, allowing the BOSCH 0261210141 to function as an exact replacement without compromising engine performance.

Installation Overview

1. Remove the Old Sensor: Disconnect the battery, locate the crankshaft position sensor on the engine block, and carefully detach the electrical connector. Unscrew the mounting bolt and remove the old sensor.
2. Prepare the New Sensor: Verify that the new sensor matches the OEM part number and inspect for any manufacturing defects. Apply a thin layer of anti‑seize compound if recommended by Bosch guidelines.
3. Mount the New Sensor: Position the sensor in the original location, align it with the mounting bolt holes, and secure it with the provided torque specifications to avoid over‑tightening.
4. Reconnect Electronics: Attach the electrical connector, ensuring a firm connection. Reconnect the battery and start the engine to confirm proper operation.

Following these steps guarantees that the sensor will deliver accurate crankshaft data, maintaining engine timing integrity and preventing potential misfires or performance loss.

Performance Benefits

• Enhanced Engine Timing: Precise position feedback allows the ECU to adjust ignition and fuel delivery in real time, improving combustion efficiency.
• Improved Fuel Economy: Accurate sensor data reduces wasted fuel by ensuring optimal spark timing across all engine speeds.
• Reduced Emissions: Correct timing minimizes incomplete combustion, lowering harmful exhaust emissions and helping vehicles meet stringent environmental regulations.
• Reliability & Durability: The sensor’s robust design resists wear from high temperatures and mechanical stress, providing consistent performance over the vehicle’s lifespan.

Quality Assurance & Certification

The BOSCH 0261210141 undergoes rigorous testing to meet or exceed Mercedes-Benz OEM standards. Each unit is inspected for electrical integrity, signal accuracy, and mechanical fit before shipment. Bosch’s commitment to quality ensures that the sensor delivers reliable performance in demanding automotive applications.

Maintenance & Troubleshooting Tips

• Regular Inspection: Periodically check the sensor for signs of corrosion or damage, especially if the vehicle operates in harsh climates.
• Electrical Connection Check: Ensure that the connector is free from debris and securely attached; a loose connection can cause erratic engine behavior.
• Signal Verification: Use an oscilloscope or diagnostic scan tool to confirm that the sensor outputs a clean, consistent pulse waveform during engine operation.
• Replace Promptly on Failure: Symptoms such as rough idle, misfires, or check engine lights may indicate sensor malfunction; replace immediately to avoid further engine damage.
