my BMW 5 Series G30/G31 (2017-2024) has a P0130 code how do I fix it

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the vehicle’s battery to ensure safety.
• Raise the vehicle using jack stands to access the exhaust system.

2. Remove the Oxygen Sensor

• Locate the oxygen sensor in Bank 1 (usually near the exhaust manifold).
• Use an oxygen sensor socket to carefully unscrew and remove the old sensor from the exhaust system.
• Disconnect the electrical connector from the oxygen sensor.

3. Inspect and Clean

• Inspect the oxygen sensor port for debris or carbon buildup. Clean the area with a suitable cleaner if necessary.
• Check the wiring harness and connector for any signs of damage or corrosion. Repair or replace as needed.

4. Install the New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
• Screw the new oxygen sensor into the exhaust system and tighten it to the manufacturer's specifications (usually around 30 Nm).
• Reconnect the electrical connector to the new oxygen sensor.

5. Reconnect Battery and Test

• Reconnect the vehicle’s battery.
• Start the engine and allow it to reach operating temperature.
• Use the OBD-II scanner to verify that no error codes are present and monitor the oxygen sensor readings.
