kia rio 1.4 crdi 2 ecodynamics ISG problems

[hopefulpolecat]

Hi there hope someone can help me, i have a 2012 kia rio that had some problems last year, a turbo seal went and oil got into the fuel system causing it to go a bit crazy by itself (diesel runaway) but engine didnt seize or explode just blocked the DPF. i changed the turbo and egr valve but couldnt start it, left it sitting for about 8 months. now i have had the DPF cleaned its running but coming up code "P062E fuel injector driver circuit performance (bank 2)" cant seam to find any obvious problems seams to idle fine and all connections are ok. the other issue is with the ISG i just have to turn the key to ignition and it will suddenly start itself wether it is in gear or not. Any help or suggestions would be appreciated
