Order of inspection
P0380 Glow Plug/Heater Circuit A Medium
The P0380 code means the circuit that powers the diesel glow plugs is not responding the way the computer expects. The typical symptom is hard starting when cold, with white smoke and a rough idle for the first few minutes, while a warm engine runs perfectly normally. It is usually an open glow plug, but the module, relay, fuse or wiring can cause it too.
