I replaced the faulty MOSFETs on the ECU (mine happened to be 1&2) and then changed out one of the coils (ECU took it with it). $80 later my car is up and running. Never will I take my car back to the dealership, I am out of warranty and their while goose chase diagnostics end up being pricey. The pathetic thing is the fault code clearly states 'Internal Electronic Malfunction' (something like that) and they look at fueling first.
Dealership Techs love to ignore codes, i'm assuming they operate on the assumption that all owners are clueless and have no idea how their cars operate. A few weeks back I brought my car in with lambda o2 codes, the precat o2 was clearly fried, and they tried to blame it on my dci. What do you was a precat o2
