New problem....P0683, white smoke on start
New problem, appeared a week ago.
White smoke upon every cold start (8+ hours standing) for the first 30 sec
dash give pre-heat error message
Reader returns following fault code = P0683
Swapped out glow plug relay - no change
Glow plugs are fine - all .5-.8Ohm
Injectors are sealed properly, local indie did a flow/return test, all good.
correction values all normal and similar.
Waiting for their expert to get back from holiday, but their not sure what step to take next...
Apparently, could be glow plug ECU, but this is just speculation.
any suggestions on what would be next port of call??
