The signum has just gone through her mot today , passed without any issues , but she also had a service while she was there one of the issues that came up was a fault code of po606 which according to the fault code chart transfers too pcm processor fault other fault,s that also arose were po100 maf sensor po638 boost sensor fault and po338 glow plug sensor fault .
what i am after is has anyone come across this po606 fault before and does anyone know what it relates to, or is it purely connected to one of the other fault codes raised
