Car in limp, fault code P0652.Leon diesel in limp.

[martin j.]

Hi all, 2.0l diesel non CR, above code showing, also reader shows “sensor reference voltage B circuit low”. Car has egr valve modded out, I wonder if a plug in the loom that is redundant has been left hanging loose and damped out due to heavy rain, straws clutched, or does anyone have another ( correct ) answer.? Cheers guys.

Sorted, found a section of loom rubbing and allowing an earth throwing an error.
