Though it may sound like a daunting task, changing the oxygen sensor on your VW Beetle is easy. Repair shops will charge a hefty fee for replacing your sensor, but you can do it in an hour with just a few tools. A faulty oxygen sensor will cause your Bug to run poorly and also cause a decrease in fuel economy. Most repair manuals state that you will need a special socket for removal, but since the sensor is mounted up on a boss, a simple box wrench will suffice. Visit your local auto parts and pick up a new sensor. The sensor should cost around $80 dollars.

Step 1

Start your car and drive around till the vehicle reaches the normal operating temperature. Park on a level surface and set the parking brake. Chock the rear wheels.
