Salam hope all of you are fine.. I recently bought a vitz 2006 Eco idle.. But the check light is contantly on so i went to mechanic he check all the things and traced the fault the previous owner misplaced the immobilizer key ( though i found it beneath the eco system machine & key is perfectly working) his stupid mechanic change the computer from eco idle to simple D5 vitz computer. So now i want a eco idle comp. does any 1 know the part number of comp & how much it cost?
