I finally figured out my CEL was caused by the front O2 sensor and not the post-cat one, so I bought a Bosch universal 4 wire from Autozone. After cutting it and everything, I realized the one on the car is a five wire sensor, so now I need a wideband. Does anyone have experience with this one:

Just want to make sure that it will work.

Also, I need a new owners manual. I found some on eBay but am not sure if the TT manuals cover a range or if I need to get the specific one for my 2003.

Thanks.

 

send that one back and use the right part.
i found one for an AWP on egermanparts after 2 minutes on google.
the part number is C5010-89311.
i'm surprised that the "universal" sensor didn't come with instructions on how to wire it into systems that have different wire combinations.
use waterproof wire nuts to make your connections.

 

I ordered the one off of eBay, and it worked perfectly. Plugged right in, and haven't had the CEL come on for over 100 miles.
