Oxygen sensor on the C43

Hi guys, I had an engine light come up about a month ago. I had the codes checked by a local mechanic that does only German cars. He said that it was the Oxygen sensor but it wasn't active, and thus he reset it. Yesterday the light came up again, so I guess I am going to have to replace the sensor. Does anyone know which sensor it is and where I can buy it ? My cousin has a shop and it would be good if I can buy it and replace it there. Any help is going to be appreciated.

Thanks!
