Persistent P0670 OBD Code
I have a 2010 WH (same as USA WK) diesel Grand Cherokee. Had the OBD code P0670 "Glow Plug Control Module open circuit" showing. Replaced the module (and the glow plugs) but after three days and many starts it still shows the P0670 code and is slow to start when cold (although its still warm hear in Australia). The new part is a different shape to my old one and doesn't seem to be earthed? Any help anyone?
