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!
