Smokey coils and engine lights

Firstly my lovely K12 had coils 1 and 2 short and the smoke came out of the coils. I have replaced the damaged coils, but the car is still running poorly, and the engine light is on.
My next thought that it could be the ECU, so that will be my next part that I will replace.
Does anybody have an idea of what else could be wrong, and is there a way of getting the codes with a laptop?
Any suggestions will be welcomed.
 
By 'coils' im assuming you mean coilpacks? And it might be a bad/improper fuel mixture if you have smoke coming out of the coilpacks, unless its the coilpacks themselves melting in which case it could be something to do with spark timing leading to the engine overheating and thus melting the coilpacks
 
Any errors stored in ECU memory logger shoul be erased after the repair, and only after tester shows no errors you can drive thecar.
You changed the two melted coils but the errors are still there. The engine is not running fine because of that
