Ours does this alot now. 2011 FR (face lift)
Had it checked by dealer during service before its first MOT. They said they couldn't replicate it.
I believe you can reset all the capacitors by disconnecting the battery and touching live and negative feeds together to resolve, but i'm not willing to do that.
I'm going to take ours to a non dealer to have some other faults looked at and get them to investigate at the same time.
