I've got a 17 plate grand cmax. Yesterday after turning it over 'Vehicle Network Communication Error came up on the MMI with no lights or errors on the dash. Everything went black on the dash no revs/speed, indicators, mmi, and power to the engine completely stopped. After a few minute the car started but without the dash/indicators/mmi working. After 5 mins of driving these slowly came back on one after the other.
Got battery checked and this is good at 97%
Today whilst driving, same error on the mmi, the dash went off, no hazards/indicators and the car cut out immediately. Its now a none starter. I've dropped it at the local garage ready for tomorrow, but is this going to be a dealer job?
Any body have any ideas what the problem might be?

Thank you!
