Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the downstream O2 sensor on this 2001 Volkswagen Beetle. It's the same part and similar process on these Beetles from 2001 to 2005. The items you'll need for this are a new downstream O2 sensor from 1AAuto.com, a 10 millimeter socket and ratchet, a flat blade screwdriver, a 7/8 inch wrench, and jack and jack stands.
Raise your vehicle. Your downstream O2 sensor is located right here and the harnesses are inside this box. You just have to remove these two 10 millimeter nuts to get inside. Inside here, you'll see both of your O2 sensor harnesses. Just pull them free from those brackets. Then, insert a flat blade screwdriver into the slot on the top of the harness, and pry it out, and disconnect, and then pull the harness from these clips. Using a 7/8 inch wrench, just loosen up and remove the O2 sensor.
On the left, is the old O2 sensor; on the right, is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Insert your new O2 sensor and twist it into place. Tighten it up with your 7/8 inch wrench. Reclip the harness. Then reconnect it. Push both the harnesses back into the brackets. Push the box back onto the studs and then replace those two 10 millimeter nuts. Then you're all set.

In this video I have a couple of oxygen sensors with me. While there are some aesthetic differences here, the wire lengths are a little different, the actual body and tip of the sensor are a little different, the threads and gasket are the same, and on the other end the connections are actually the same. I can plug these into either position on our vehicle. But if I had to ask you which one's upstream and which one's downstream, you probably can't tell just from looking at them. That's true of most oxygen sensors. The way you determine whether or not an O2 sensor is upstream or downstream is all done visually.
Your oxygen sensor position can be determined relative to your catalytic convertor. As the name suggests, upstream sensors will be located upstream or ahead of, in front of, above, closer to the engine than your catalytic convertors. This means that they see the exhaust gasses first. They then go through the catalytic convertor and to the downstream oxygen sensor, which will either be located in the catalytic convertor like our vehicle here, or after the catalytic convertor to monitor the gasses coming out of the cat and make sure that it's being efficient relative to the readings of the upstream O2 sensor.
The other determination you need to make is bank one versus bank two. Determining which bank is which can be done by looking at a picture of your vehicle's firing order. Whichever bank contains cylinder one is going to be bank one, and the other one, regardless of whether or not cylinder two is in it, is going to be bank two by default. These banks are true of V engines like V8s, V6s, and flat engines like Porsches and Subarus that have individual banks.
On inline four-cylinder engines, as long as they have one exhaust manifold like a Jeep four-liter or a four-cylinder Honda engine, you'll only have one bank with an upstream and downstream O2 sensor. There will be no bank two on the engine.
On our vehicle here, this is the passenger side, which we've already determined from the firing order is bank one. We have our upstream sensor here closest to the engine ahead of the cat. Then we have our downstream or sensor two here inside of the catalytic convertor. This could also be located somewhere after the cat. Here I have my two sensors for the vehicle. While they are aesthetically different, we can now tell this is my upstream sensor because it looks just like the upstream sensor I have up there. This is my downstream sensor. Now that we know which one's which, we can order the right part, correct the problem, and fix you up right.

Had to heat original to remove,new one installed perfect and check engine light is gone
I bought an Amazon O2 sensor that was supposed to fit my car. The plug did not match. I sent it back and ordered this from 1A Auto. It fit perfectly and is working fine. Very happy with the experience.
So far is working great
Used O2 sensor for beetle and fit perfectly! Shipping was very fast and great customer service
Great fit for our 2000 Beetle, *except* we had to wrap a small section so it would stay in the harness-to-body clip. Otherwise, all seems to be working fine.
Thank you for your inquiry! Yes, this part will fit your 2008 VW Beetle L5 2.5L Downstream .
