Sorry, didn't know where to post this. I need to replace the rear/second O2 sensor on my daughter's '97 Golf. It is a 2.0 w/ ATX. I don't have a lot of experience with these cars. Any help would be greatly appreciated.
It should be fairly straight forward....get an O2 sensor socket from any respectful auto parts store, and unscrew the sensor as you would any other. I wouldn't think it would be a weird size, but it is a VW, so anything is possible. Hopefully they bothered to spend the extra $1 and put a connector inline for the sensor, otherwise you'll be cutting the wires and soldering the new one in.
