Error Code
2017 E 300 4 Matic (I know it's an E Class, but I wanted to see if anyone here had the same issue with their C300/M257 engine)
Got a check engine light on yesterday as I was leaving the parking lot:
1: P060600 - An internal control module fault exists in the processor
2: P217700 - The mixture (cylinder bank 1) is too lean in partial load operation.
I cleared all the codes with my OBDII scanner and drove it around the parking lot and nothing. Turned the car on the next morning and drove about 8-10 miles, check engine light comes back on (I haven't scanned the codes yet, waiting to do that in the AM). The car drives fine and nothing feels different. I put in 93 Octane fuel from Mobil/Shell per usual. Spark plugs have less than 20,000 miles on them and I've already replaced the PCV valve and know the system doesn't have a leak.
Would anyone know what the issue could be? I was thinking maybe the O2 sensor/MAF sensors might need to be replaced?
Has anyone had any of these codes/problems in the past that can give any insight on the issue on either of the codes?
Any help is appreciated!

The car is telling you that this is problem with the "An internal control module fault". You would need to find the control module and see if anything is bad with it.
