how to fix the P0130 oxygen sensor issue in Volkswagen Golf Seventh Generation (2013-2020)

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical shorts and ensure safety.

2. Remove the Oxygen Sensor

• Locate the upstream oxygen sensor (Bank 1 Sensor 1) on the exhaust manifold or front pipe.
• Use an oxygen sensor socket or wrench to carefully unscrew the sensor from its threaded port.
• If the sensor is stuck, apply penetrating oil and let it sit for a few minutes before attempting removal again.

3. Inspect and Clean

• Inspect the sensor port for any carbon buildup or debris. Clean the port with a wire brush or appropriate cleaning solution.
• Check the condition of the wiring harness and connectors for any signs of wear or damage. Replace if necessary.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-coated) to prevent seizing.
• Screw the new oxygen sensor into the port by hand initially, then tighten it with the oxygen sensor socket/wrench to the manufacturer’s torque specification (typically around 30-40 Nm).
• Reconnect the electrical connector to the oxygen sensor ensuring a secure fit.

5. Reconnect Battery and Test

• Reconnect the battery terminal.
• Start the engine and allow it to reach operating temperature.
• Check for any exhaust leaks around the new sensor installation.
