Hi
I'm not too sure about the ECU codes, But my N/A just stopped one day would turn over but no go. have you got a Mk1 or Mk2 PTU?? if Mk1 think they are bit notorious for going wrong. I cut mine open with a dremil like device and fixed a broken wire in side. All worked and she ran as good as new, well till I had the head gasket go!! dogh
hope this helps, and there is a how to somewhere online.
