Lately I seen to be getting allot of missfire issues that turn out to be coil packs. Maybe the heat of summer, and the age of the coils is causing them to degrade. Replace the coil and all is good. I have had a run of this in customers cars over the last 2 months.
I assume this is N54. If N55, as scoobs said, the later DME code is allot more tolerant than the earlier.
