Code #2 on a 94 E320 Wagon
 

Hi,

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!

Carlos.

Do a search on here on W124 codes. Get to know Arthur Dalton:). These cars are straight forward as being able to read all the codes. You are just scratching the surface in regards to what an individual can do with a home made reader.

I think code 2 is the coolant temperature sensor.
