Apparently you need all replaced, and each one costs $700 or something ridiculous. I have had the worst luck with this car. Had to pay for both turbos to get replaced at 91 KM's.
Fault code for spark plug? If it was a code for a misfire it will more likely be a bad ignition coil than a plug. Common issue on these. Assuming it's a n54? Could always swap a coil on the bad cylinder and scan the car again to see if the code follows the coil.
