I was thinking along the same lines, or there is some accumulated oil/dirt crude down in the spark plug connection area that is causing a small short to ground on the driver's side.
He also spoke of a TCM tune; May have something to do with that. Getting back to who did the tune and asking for info, or contacting the Mercedes Swap shop may help to figure out that P2314 code.
Seems like a good scan tool (DRB III or emulator) could figure out what is going on. Many of the OBD II scanners won't work on the Crossfire ABS system.
