Endeavour Glow Plug Issue
Summary of the thread
The 2004 Ford Endeavour diesel exhibits a persistent preheating lamp, a check engine light, and excessive smoke when accelerating. These symptoms suggest a potential issue with the glow plug system, possibly due to a defective glow control unit cable or plug connection. It is advised to seek professional assistance for diagnosis and repair, as confirmed by a mechanic who identified and fixed the defective connection.

I haven't inspected the glow plugs; I lack the expertise and equipment. Given your experience, should I prioritize inspecting the glow plugs, or are there other potential causes to investigate beforehand? What symptoms did you experience with your Endeavour?

My symptoms were identical: persistent preheating lamp, check engine light, and smoke. Since you lack the tools for a proper glow plug diagnosis, and a defective cable or plug connection is suspected, seek professional assistance. The engine's electronic control unit is complex and diagnosis requires specialized tools. It could be a faulty glow plug, the control unit, or a bad connection. Go to a reliable workshop.

Following your advice, I consulted a qualified mechanic, who confirmed the glow control unit's cable or plug connection was defective. The repair cost 95€. Thanks again!

I recall something similar with my Ford Endeavour. The preheating lamp refusing to extinguish is a classic symptom. Smoke upon acceleration points to a potential issue within the glow plug system. Have you inspected the glow plugs themselves? Check their individual resistances with a multimeter. A faulty glow plug can trigger a cascade of errors, confusing the control unit.
