how to fix P0130 code in my BMW X3 F25 (2011-2018)?

Solution

1. Preparation

• Gather tools and parts: OBD-II scanner, multimeter, socket set, oxygen sensor socket, and new oxygen sensor.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Disconnect Battery

• Disconnect the negative terminal of the battery to prevent electrical shock.
• Wait for at least 10 minutes to allow any residual power to dissipate.

3. Remove Old Oxygen Sensor

• Locate the upstream oxygen sensor (Bank 1 Sensor 1), which is typically found in the exhaust manifold or front of the catalytic converter.
• Use an oxygen sensor socket to carefully unscrew the old sensor. Ensure no debris falls into the exhaust system.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-coated).
• Screw the new oxygen sensor into the exhaust system by hand to avoid cross-threading, then tighten it with the oxygen sensor socket to the manufacturer’s specifications (usually around 30 Nm).

5. Reconnect Battery

• Reconnect the negative terminal of the battery and ensure it is securely fastened.

6. Clear Codes and Test

• Use the OBD-II scanner to clear the P0130 code.
• Start the engine and allow it to reach operating temperature.
• Perform a test drive to ensure the check engine light does not return.
