Check Engine Light Turned on Under WOT
Over the weekend I was out in the country ripping it a few times. But on one long run, my CEL turned on. This morning on my way to my buddies shop the CEL turned off. I still had by friend run a scan of the car and P2093 was the only code in the record. I did look up the definition on here, and this is all that came up, does anyone know have this code come up before and If so what was the issue? My car is running fine now, it is as though nothing happened. The only things done to the car are a Renntech intake and a Renntech Tune.
P2093 (B) self-adaptation L Cyl bank for enrich at partial load above limit.
My Car is a 2008 E63 FYI

Sounds like a vacuum leak to me or even an air mass meter. Vacuum leaks on 156 engines are very common. This won't be a guessing fix here. Find someone that knows this engine to properly diagnose it.
