I need some advice. My check engine light came on yesterday. I read the codes and code #2 came up, which is the o2 sensor?? is this true? If it is, my questions are:
- can i do it myself?? I'm pretty new to my MB since I got it a month ago, and I have no car experience but I'm willing to work on it as long as i have some documentation/advice.
- should I buy the OEM part? or should I go with the Universal part?
- where is the o2 sensor in my car?
Thanks a lot in advance!
