Pal has had (we think) an EDIS4 coil fail. He's a long way off, so I've not seen it myself.
One cylinder of a pair appears not to be firing at all. Which sort of doesn't make sense to me. But swapping the coils - it's an eight cylinder - moves the fault too.
Any guesses what could cause this? The resistance readings of the coil seem normal at about 1 ohm primary, 30,000 ohms secondary.
