I have had 3 of these in the last few months all with damaged under bonnet fuseboxes.
I pulled the first one apart and found the top left corner of the pcb burnt. The second car also had burning in the same place.
I sourced a used box as the customer was short of cash and the car has been fine since.Both of the other cars had used fuseboxes fitted and have all been perfect since.
