Just had the same problem with mine, N51 motor but i believe everything internally should be the same to an N52 just exhaust pipe modifications, as i just read in the AA exhaust thread, but yea had a rough idle outta no where would misfire on WOT and bog down at cursing speeds took it into the dealer and ended up being #4 coil pack was shot, actually had oil inside the cylinder and the spark plug hold was also flooded with oil and i was leaking air out of my valve cover gasket, as they did a smoke test and realized that, but since then knock on word cars running fine no problems so far, hope this helps you guys oh and I'm around 80k mileage wise
