Just to add to this one, I have monitored the amp draw to heater circuit for approx 1/2 on scope, including tugging wiring loom and cant find a problem
How ever, with it idling in the workshop there is noticable smoke screen, both water and oil low but thinking possible turbo failing ( this had oil pick up issue a few months ago.)
Still cant see why this would log heater circuit fault, any thoughts ?
