Service Engine Soon light came on after merging onto the interstate in DS mode and driving on the freeway for about five miles (8,000 miles). Light stayed on for 2 days. Error code is captured even when the light goes off so the dealer determined it was a bad oxygen sensor. The E90 has several oxygen sensosrs. No problem to replace the sensor but the part took 2 days to come in.
