Hey all,
Any techs here that can help me with a 2012 Juke dci preheat problem.
What are the conditions that must be met for the heater plugs to be used?

When turning on the ignition from cold the ecu isn't requesting glow plugs.
All temperature sensors are correct and within range (ambient temp ~1 degree at the min)
Actuation test with scan tool triggers glow plugs and the signals to and from the relay are correct (checked with scope).
Identical vehicle at same temperature triggers glow plugs as expected.
I'm sure its just input condition not being fulfilled.

Any advice would be greatly appreciated
