how to fix P0130 code on my BMW 5 Series F10/F11 (2010-2017)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety goggles.
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Disconnect the battery to ensure safety during the repair.

2. Inspect Wiring and Connectors

• Remove the engine cover if necessary for better access.
• Visually inspect the wiring harness leading to the Bank 1 sensor 1 for any frayed or damaged wires.
• Disconnect the oxygen sensor connector and check for corrosion or dirt. Clean if necessary.

3. Test the Oxygen Sensor

• Reconnect the battery and start the engine.
• Use the multimeter to measure the voltage output of the oxygen sensor (should fluctuate between 0.1V to 0.9V).
• If the voltage remains constant, the sensor may need to be replaced.

4. Replace the Oxygen Sensor

• Using a socket, remove the old oxygen sensor from its location in the exhaust manifold or downpipe.
• Apply anti-seize compound to the threads of the new sensor (if not pre-coated).
• Install the new sensor by hand, then tighten it to the manufacturer's specification (usually around 30 Nm).
• Reconnect the oxygen sensor connector securely.

5. Final Checks

• Reconnect the battery and clear the check engine light using the OBD-II scanner.
• Start the engine and let it reach operating temperature.
