From reading the forums across the board it would seem that replacing of the fuse box and ECU is rife across models in the UK. If you are confronted with this repair by a franchised dealership ask if they have checked the vehicle main earth lead. When I asked for the displaced fuse box and ECU to be LEFT IN THE CAR the repair suddenly became a replacement earth lead with a "strip and clean" of the fuse box. With the exception of fluids, friction parts and contaminated parts ALWAYS ASK FRANCHISED DEALERS TO LEAVE DISPLACED PARTS in the boot. Please make this a sticky in any models affected by this "problem". Thanks
