Check Engine Light - 2008 320i E90

For the past 4 or so months I have had the same reoccurring problem with my 2008 320i E90.
One day when I was on the highway with the cruise control on my check engine light came on mysteriously, the car seemed to be running fine so I took my car to my local BMW dealership but they could not find the issue and reset the light to off. Then about 3-4 weeks later again on the freeway in cruise control the same issue, this time my car was close to being due for a service and the dealership looked at the issue again and identified one of the oxygen sensors, so they changed it. Everything was going fine then roughly 3-4 weeks later again the same problem, on the highway in cruise control. This time the dealership switched the sensors to see if there was something wrong with one side, they reset the warning light and off I went. They still cannot identify the issue. Now the other night roughly 4 weeks after my last visit to the dealership the same issue occurred on the highway in cruise control. I donít want to take it back to the dealership because they seem to have no idea what the issue is and Iím fed up with pouring money into the issue without it being resolved. Has anyone had a similar issue? Or have any ideas?
