I had an O2 sensor fault. The dealer wanted more than double for just the same sensor, so I decided to look around for an alternative. This part showed as being compatible with my 2003 Audi allroad 2.7T, in additional to several other makes/models. In case you were unaware, Bosch is the manufacturer of many of the VW/Audi parts, including O2 sensors. Upon initial inspection, I found the replacement to appear to be identical in both shape and construction as the original. It was easy to install, and simply worked. The kit comes with 2 different wiring harness housings. One of which is pre-installed. For my application, I had to swap out the housing to the other which was included. Unfortunately the included instructions do not show much about this part of the process. If you are not familiar with VW/Audi wiring housing, I strongly suggest searching for a how-to and/or video on how to remove the cable terminals from one housing and install them into another. It's not difficult, but does require the know-how, otherwise you can damage/break the housing and/or terminals. Summary: Item was compatible and worked flawlessly. Easy to install, with no fitment issues. This O2 replacement is identical in shape, appearance, function, and quality as the original, but at less than half the price you would pay at the dealer. Recommended!
