Did not meet expectations
This was a hard to reach job and i was working dilegently to try and plug in to find out that the freaking connector was not plug and play even though it was bought vehicle specific. It was just i little size difference to make it not work. So I finally resulted in the ghetto way just because I was tired and frustrated to cut off the connector and just wired together with a splice and electrical tape. Wow was not happy about that but it turned the check engine light off. Overall A1 did not really impress me like all there helpful youtube videos ussually say and do. Sometimes its better to just stay with you local parts store so you can return real quick. In this case im stuck with 3 more brand new 02 sensors that dont plug and play, and that sucks. I guess you live and you learn
